10 This manual documents feh 3.1.3
11 Compile-time switches: libcurl support enabled, natural sorting support
13 enabled, Xinerama support enabled, builtin EXIF support enabled. This is
14 a debug build.
15
17 feh is a light-weight, configurable and versatile image viewer. It is
18 aimed at command line users, but can also be started from graphical file
19 managers. Apart from viewing images, it can compile text and thumbnail
20 listings, show (un)loadable files, set X11 backgrounds, and more.
21 Features include filelists, various image sorting modes, custom action
23 scripts, and image captions. feh can be controlled by configurable key‐
24 board and mouse shortcuts, terminal input and signals. When no file
25 arguments or filelists are specified and --start-at is not used, feh dis‐
26 plays all files in the current directory.
27 EXIF tags are supported either using exiv2 / exifgrep via --info (see the
29 USAGE EXAMPLES section), or as a builtin feature by compiling feh with
30 exif=1. In this build of feh, builtin EXIF support is enabled.
31
33 feh is based on various modes, which are selected at startup by command
34 line options.
35 Slideshow mode is the default. It opens a window and displays the first
37 image in it; the slideshow position can be advanced (or otherwise
38 changed) using keyboard and mouse shortcuts. In slideshow mode, images
39 can be deleted either from the filelist or from the disk, a changed
40 filelist can also be saved to the disk and reopened at a later time. An
41 image can also be read from stdin via "feh -".
42 Montage mode forms a montage from the filelist. The resulting image can
44 be viewed or saved, and its size can be limited by height, width or both.
45 Index mode forms an index print from the filelist. Image thumbnails are
47 shown along with the filename, size and dimensions, printed using a true‐
48 type font of your choice. The resulting image can be viewed or saved,
49 and its size can be limited by height, width or both.
50 Thumbnail mode is like index mode, but the mini-images are clickable and
52 open the selected image in a new window.
53 Multiwindow mode shows images in multiple windows, instead of as a
55 slideshow in one window. Don't use with a large filelist ;)
56 List mode doesn't display images. Instead, it outputs an ls-style list‐
58 ing of the files in the filelist, including image info such as size, num‐
59 ber of pixels, type, etc. There is also a Customlist mode which prints
60 image info in a custom format specified by a printf-like format string.
61 feh can also list either all the loadable files in a filelist or all the
63 unloadable files. This is useful for preening a directory.
64
66 feh can open any format supported by imlib2, most notably jpeg, png, pnm,
67 tiff, and bmp. The gif format is also supported, but only for static
68 images. In case of animations, only the first frame will be shown. If
69 the convert binary (supplied by ImageMagick) is available, it also has
70 limited support for many other file types, such as svg, xcf and otf. If
71 dcraw is available, feh also supports RAW files provided by cameras and
72 will display the embedded thumbnails. Use --conversion-timeout timeout
73 with a non-negative value to enable support for these formats.
74
76 -A, --action [flag][[title]]action
77 Specify a shell command as an action to perform on the image. In
78 slideshow or multiwindow mode, the action will be run when the
79 action_0 key is pressed, in list mode, it will be run for each
80 file. In loadable/unloadable mode, it will be run for each load‐
81 able/unloadable file, respectively. In thumbnail mode, clicking
82 on an image will cause the action to run instead of opening the
83 image.
84 If flag is ";", feh will reload the current image instead of
86 switching to the next one (slideshow mode) or closing the window
87 (multiwindow mode) after executing the action. If [title] is
88 specified (note the literal "[" and "]"), --draw-actions will
89 display title instead of action in the action list. Note that
90 title must not start with a space. If it does, the action is
91 handled as if it did not have a title. This special case exists
92 for backwards compatibility reasons and makes sure that actions
93 like "[ -L %F ] && foo" still work.
94 The action will be executed by /bin/sh. Use format specifiers to
96 refer to image info, see FORMAT SPECIFIERS for details. Example
97 usage: "feh -A "mv ~/images/%N" *".
98 --action1 .. --action9 [flag][[title]]action
100 Extra actions which can be set and triggered using the appropri‐
101 ate number key.
102 --auto-rotate
104 (optional feature, enabled in this build) Automatically rotate
105 images based on EXIF data. Does not alter the image files.
106 -Z, --auto-zoom
108 Zoom pictures to screen size in fullscreen / fixed geometry mode.
109 -x, --borderless
111 Create borderless windows.
112 --cache-size size
114 Set imlib2 in-memory cache to size MiB. A higher cache size can
115 significantly improve performance especially for small slide
116 shows, however at the cost of increased memory consumption. size
117 must be between 0 and 2048 MiB and defaults to 4.
118 -P, --cache-thumbnails
120 Enable thumbnail caching. Thumbnails are saved in
121 $XDG_CACHE_HOME/thumbnails, which defaults to
122 ~/.cache/thumbnails. Note that thumbnails are only cached if the
123 configured thumbnail size does not exceed 256x256 pixels.
124 -K, --caption-path path
126 Path to directory containing image captions. This turns on cap‐
127 tion viewing, and if captions are found in path, which is rela‐
128 tive to the directory of each image, they are overlayed on the
129 displayed image. E.g. with caption path "captions/", and viewing
130 image "images/foo.jpg", the caption will be looked for in
131 "images/captions/foo.jpg.txt".
132 --conversion-timeout timeout
134 feh can use ImageMagick to try converting unloadable files into a
135 supported file format. As this can take a long time, it is dis‐
136 abled by default. Set timeout to a non-negative value to enable
137 it. A positive value specifies after how many seconds conversion
138 attempts should be aborted, zero causes feh to try indefinitely.
139 Negative values restore the default by disabling conversion alto‐
140 gether.
141 -L, --customlist format
143 Don't display images, print image info according to format
144 instead. See FORMAT SPECIFIERS.
145 -G, --draw-actions
147 Draw the defined actions and what they do at the top-left of the
148 image.
149 --draw-exif
151 (optional feature, enabled in this build) display some EXIF
152 information in the bottom left corner, similar to using --info
153 with exiv2 / exifgrep .
154 -d, --draw-filename
156 Draw the file name at the top-left of the image.
157 --draw-tinted
159 Show overlay texts (as created by --draw-filename et al) on a
160 semi-transparent background to improve their readability
161 --edit Enable basic editing of files. This makes rotation and mirroring
163 (bound to "<", ">", "|", and "_" by default) change the underly‐
164 ing file and not just its displayed content.
165 -f, --filelist file
167 This option is similar to the playlists used by music software.
168 If file exists, it will be read for a list of files to load, in
169 the order they appear. The format is a list of image file names,
170 absolute or relative to the current directory, one file name per
171 line.
172 If file doesn't exist, it will be created from the internal
174 filelist at the end of a viewing session. This is best used to
175 store the results of complex sorts (-Spixels for example) for
176 later viewing.
177 Any changes to the internal filelist (such as deleting a file or
179 it being pruned for being unloadable) will be saved to file when
180 feh exits. You can add files to filelists by specifying them on
181 the command line when also specifying the list.
182 If file is "-", feh will read the filelist from its standard
184 input.
185 -e, --font font
187 Set global font. Should be a truetype font, resident in the cur‐
188 rent directory or the font directory, and should be defined in
189 the form fontname/points, like "myfont/12".
190 -C, --fontpath path
192 Specify path as extra directory in which to search for fonts; can
193 be used multiple times to add multiple paths.
194 --force-aliasing
196 Disable anti-aliasing for zooming, background setting etc.
197 -I, --fullindex
199 Same as index mode, but with additional information below the
200 thumbnails. Works just like "feh --index --index-info
201 "%n\n%S\n%wx%h"". Enables MONTAGE MODE OPTIONS.
202 Note: This option needs to load all images to calculate the
204 dimensions of the feh window, so when using it with many files it
205 will take a while before a feh window is visible. Use --preload
206 to get a progress bar.
207 -F, --fullscreen
209 Make the window fullscreen. Note that in this mode, large images
210 will always be scaled down to fit the screen, and --zoom zoom
211 only affects smaller images and never scales larger than neces‐
212 sary to fit the screen size. The only exception is a zoom of
213 100, in which case images will always be shown at 100% zoom.
214 When combined with --thumbnails, this option only affects images
216 opened from the thumbnail overview. The thumbnail list itself
217 will still be windowed.
218 -g, --geometry width x height | + x + y | width x height + x + y
220 Use a fixed window size as specified in the X-style geometry
221 string, e.g. 640x480. An optional +x+y window offset can be
222 specified. Combine with --scale-down to scale down larger images
223 like in fullscreen mode. Note that this option does not enforce
224 the window size; changing it by a tiling WM or manually is still
225 possible. However, auto-resize remains disabled.
226 -Y, --hide-pointer
228 Hide the pointer (useful for slideshows).
229 -B, --image-bg style
231 Use style as background for transparent image parts and the like.
232 Accepted values: default, checks, or an XColor (e.g. "black" or
233 "#428bdd"). In windowed mode, the default is checks (a checkered
234 background so transparent image parts are easy to see). In
235 fullscreen and background setting mode, checks is not accepted
236 and the default is black.
237 -i, --index
239 Enable Index mode. Index mode is similar to montage mode, and
240 accepts the same options. It creates an index print of thumb‐
241 nails, printing the image name beneath each thumbnail. Index
242 mode enables certain other options, see INDEX AND THUMBNAIL MODE
243 OPTIONS and MONTAGE MODE OPTIONS.
244 --info [flag]command_line
246 Execute command_line and display its output in the bottom left
247 corner of the image. Can be used to display e.g. image dimen‐
248 sions or EXIF information. Supports FORMAT SPECIFIERS. If flag
249 is set to ";", the output will not be displayed by default, but
250 has to be enabled by the toggle_info key.
251 --insecure
253 When viewing files with HTTPS, this option disables all certifi‐
254 cate checks. It allows images on sites with self-signed or
255 expired certificates to be opened, but is no more secure than
256 plain HTTP.
257 -k, --keep-http
259 When viewing files using HTTP, feh normally deletes the local
260 copies after viewing, or, if caching, on exit. This option per‐
261 manently stores them on disk, either in the directory specified
262 by --output-dir, or in the current working directory.
263 --keep-zoom-vp
265 When switching images, keep zoom and viewport settings (zoom
266 level and X, Y offsets)
267 -l, --list
269 Don't display images. Analyze them and display an ls(1) - style
270 listing. Useful in scripts to hunt out images of a certain
271 size/resolution/type etc.
272 -U, --loadable
274 Don't display images. Just print out their names if imlib2 can
275 successfully load them. Returns false if at least one image
276 failed to load.
277 --max-dimension width x height
279 Only show images with width <= width and height <= height. If
280 you only care about one parameter, set the other to 0 (or a
281 negative value).
282 -M, --menu-font font
284 Use font (truetype, with size, like "yudit/12") as menu font.
285 --min-dimension width x height
287 Only show images with width >= width and height >= height. If
288 you only care about one parameter, set the other to 0.
289 -m, --montage
291 Enable montage mode. Montage mode creates a new image consisting
292 of a grid of thumbnails of the images in the filelist. When mon‐
293 tage mode is selected, certain other options become available.
294 See MONTAGE MODE OPTIONS.
295 -w, --multiwindow
297 Disable slideshow mode. With this setting, instead of opening
298 multiple files in slideshow mode, multiple windows will be
299 opened; one per file.
300 --no-jump-on-resort
302 Don't jump to the first image after resorting the filelist.
303 -N, --no-menus
305 Don't load or show any menus.
306 --no-screen-clip
308 By default, window sizes are limited to the screen size. With
309 this option, windows will have the size of the image inside them.
310 Note that they may become very large this way, making them unman‐
311 ageable in certain window managers.
312 --no-xinerama
314 (optional feature, enabled in this build) Disable Xinerama sup‐
315 port.
316 --on-last-slide hold | quit | resume
318 Select behaviour when trying to select the next image on the last
319 slide (or the previous image on the first slide) in a slide show.
320 With hold, feh will stop advancing images in this case and con‐
322 tinue displaying the first/last image, respectively. This is
323 intended for linear slide shows. Behaviour is unspecified when
324 using other navigation commands than previous and next image.
325 quit will cause feh to quit when trying to advance past the last
327 image in the slide show.
328 resume is the default behaviour: On the last (first) image, feh
330 will wrap around to the first (last) image.
331 -j, --output-dir directory
333 Save files to directory when using --keep-http or the save_image
334 command. By default, files are saved in the current working
335 directory.
336 -p, --preload
338 Preload images. This doesn't mean hold them in RAM, it means run
339 through them and eliminate unloadable images first. Otherwise
340 they will be removed as you flick through. This also analyses
341 the images to get data for use in sorting, such as pixel size,
342 type etc. A preload run will be automatically performed if you
343 specify one of these sort modes.
344 -q, --quiet
346 Don't report non-fatal errors for failed loads. Verbose and
347 quiet modes are not mutually exclusive, the first controls infor‐
348 mational messages, the second only errors.
349 -z, --randomize
351 When viewing multiple files in a slideshow, randomize the file
352 list before displaying. The list is re-randomized whenever the
353 slideshow cycles (that is, transitions from last to first image).
354 -r, --recursive
356 Recursively expand any directories in the command line arguments
357 to the content of those directories, all the way down to the bot‐
358 tom level.
359 --no-recursive
361 Don't recursively expand any directories. This is the default,
362 but this option is useful to override themes containing
363 --recursive.
364 -R, --reload int
366 Reload filelist and current image after int seconds. Useful for
367 viewing HTTP webcams or frequently changing directories. (Note
368 that filelist reloading is still experimental.)
369 If an image is removed, feh will either show the next one or
371 quit. However, if an image still exists, but can no longer be
372 loaded, feh will continue to try loading it.
373 -n, --reverse
375 Reverse the sort order. Use this to invert the order of the
376 filelist. E.g. to sort in reverse width order, use -nSwidth.
377 -., --scale-down
379 Scale images to fit window geometry (defaults to screen size when
380 no geometry was specified). Note that the window geometry is not
381 updated when changing images at the moment. This option is rec‐
382 ommended for tiling window managers. This option is ignored when
383 in fullscreen and thumbnail list mode.
384 In tiling environments, this also causes the image to be centered
386 in the window.
387 --scroll-step count
389 Scroll count pixels whenever scroll_up, scroll_down, scroll_left
390 or scroll_right is pressed. Note that this option accepts nega‐
391 tive numbers in case you need to reverse the scroll direction.
392 See KEYS CONFIG SYNTAX for how to reverse it permanently.
393 Default: 20
394 -D, --slideshow-delay float
396 For slideshow mode, wait float seconds between automatically
397 changing slides. Useful for presentations. Specify a negative
398 number to set the delay (which will then be float * (-1)), but
399 start feh in paused mode.
400 -S, --sort sort_type
402 Sort file list according to image parameters. Allowed sort types
403 are: name, filename, dirname, mtime, width, height, pixels, size,
404 format. For sort modes other than name, filename, dirname, or
405 mtime, a preload run is necessary, causing a delay proportional
406 to the number of images in the list.
407 mtime starts with the most recently modified image. width,
409 height, pixels and size start with the smallest. Use --reverse
410 to sort by oldest or largest first.
411 For name, filename, and dirname you can use --version-sort to
413 sort numbers naturally, so that e.g. 10.jpg comes after 2.jpg.
414 -|, --start-at filename
416 Start the filelist at filename. If no other files or filelists
417 were specified on the command line, feh will first load all files
418 from the directory in which filename resides. This way, it's
419 possible to look at a specific image and use the next / prev keys
420 to browse through the directory. See USAGE EXAMPLES for exam‐
421 ples.
422 Note: If you use relative paths in your filelist, filename should
424 also be a relative path. If you use absolute paths, it should
425 also be an absolute path. If feh cannot find an exact match, it
426 will compare basenames (filenames without the directory suffix).
427 This may lead to mismatches if several files in your filelist
428 have the same basename.
429 -T, --theme theme
431 Load options from config file with name theme - see THEMES CONFIG
432 SYNTAX for more info. Note that command line options always
433 override theme options. The theme can also be set via the pro‐
434 gram name (e.g. with symlinks), so by default feh will look for a
435 "feh" theme.
436 -t, --thumbnails
438 Same as Index mode, but the thumbnails are clickable image
439 launchers. Note that --fullscreen and --scale-down do not affect
440 the thumbnail window. They do, however, work for image windows
441 launched from thumbnail mode. Also supports INDEX AND THUMBNAIL
442 MODE OPTIONS as well as MONTAGE MODE OPTIONS.
443 -~, --thumb-title string
445 Set title for windows opened from thumbnail mode. See also
446 FORMAT SPECIFIERS.
447 -^, --title title
449 Set window title. Applies to all windows except those opened
450 from thumbnail mode. See FORMAT SPECIFIERS.
451 -u, --unloadable
453 Don't display images. Just print out their names if imlib2 can
454 NOT successfully load them. Returns false if at least one image
455 was loadable.
456 -V, --verbose
458 output useful information, progress bars, etc.
459 -v, --version
461 output version information and exit.
462 --version-sort
464 (optional feature, enabled in this build) When combined with
465 --sort name, --sort filename, or --sort dirname: use natural
466 sorting for file and directory names. In this mode, filenames
467 are sorted as an ordinary human would expect, e.g. "2.jpg" comes
468 before "10.jpg". Note that this option only has an effect when a
469 sort mode is set using --sort.
470 --xinerama-index screen
472 (optional feature, enabled in this build) Override feh's idea of
473 the active Xinerama screen. May be useful in certain circum‐
474 stances where the window manager places the feh window on Xin‐
475 erama screen A while feh assumes that it will be placed on screen
476 B.
477 In background setting mode: When used with any option other than
479 --bg-tile: Only set wallpaper on screen. All other screens will
480 be filled black/white. This is most useful in a Xinerama config‐
481 uration with overlapping screens. For instance, assume you have
482 two overlapping displays (index 0 and 1), where index 0 is
483 smaller. To center a background on the display with index 0 and
484 fill the extra space on index 1 black/white, use
485 "--xinerama-index 0" when setting the wallpaper.
486 --zoom percent | max | fill
488 Zoom images by percent when in full screen mode or when window
489 geometry is fixed. When combined with --auto-zoom, zooming will
490 be limited to the specified percent. Specifying max is like set‐
491 ting --auto-zoom, using fill makes feh zoom the image like the
492 --bg-fill mode.
493
495 These additional options can be used for index, montage and (partially)
496 thumbnail mode.
497 -a, --alpha int
499 When drawing thumbnails onto the background, set their trans‐
500 parency level to int (0 - 255).
501 -b, --bg file | trans
503 Use file as background for your montage. With this option speci‐
504 fied, the montage size will default to the size of file if no
505 size restrictions were specified. Alternatively, if file is
506 "trans", the background will be made transparent.
507 -X, --ignore-aspect
509 By default, the montage thumbnails will retain their aspect
510 ratios, while fitting into thumb-width/-height. This options
511 forces them to be the size set by --thumb-width and
512 --thumb-height. This will prevent any empty space in the final
513 montage.
514 -H, --limit-height pixels
516 Limit the height of the montage.
517 -W, --limit-width pixels
519 Limit the width of the montage, defaults to 800 pixels.
520 If both --limit-width and --limit-height are specified, the mon‐
522 tage will be exactly width x height pixels in dimensions.
523 -o, --output file
525 Save the created montage to file.
526 -O, --output-only file
528 Just save the created montage to file without displaying it.
529 -s, --stretch
531 Normally, if an image is smaller than the specified thumbnail
532 size, it will not be enlarged. If this option is set, the image
533 will be scaled up to fit the thumbnail size. Aspect ratio will
534 be maintained unless --ignore-aspect is specified.
535 -E, --thumb-height pixels
537 Set thumbnail height.
538 -y, --thumb-width pixels
540 Set thumbnail width.
541
543 In addition to MONTAGE MODE OPTIONS --alpha, --bg, --limit-height,
544 --limit-width, --output, --output-only, --thumb-height, --thumb-width,
545 the following options can be used.
546 --index-info format
548 Show image information based on format below thumbnails in index
549 / thumbnail mode. See FORMAT SPECIFIERS. May contain newlines.
550 Use "--index-info ''" to display thumbnails without any info text
551 Note: If you specify image-related formats (such as %w or %s),
553 feh needs to load all images to calculate the dimensions of its
554 own window. So when using them with many files, it will take a
555 while before a feh window becomes visible. Use --preload to get
556 a progress bar.
557 -@, --title-font font
559 Set font to print a title on the index, if no font is specified,
560 no title will be printed.
561 -J, --thumb-redraw n
563 Redraw thumbnail window every n images while generating thumb‐
564 nails. Redrawing takes quite long, so the default is 10. Set n
565 = 1 to update the thumbnail window immediately. With n = 0,
566 there will only be one redraw once all thumbnails are loaded.
567
569 In many desktop environments, feh can also be used as a background set‐
570 ter. Unless you pass the --no-fehbg option, it will write a script to
571 set the current background to ~/.fehbg. So to have your background
572 restored every time you start X, you can add "~/.fehbg &" to your X
573 startup script (such as ~/.xinitrc).
574 Note that feh does not support setting the wallpaper of GNOME shell desk‐
576 tops. In this environment, you can use "gsettings set
577 org.gnome.desktop.background picture-uri file:///path" instead.
578 For --bg-center, --bg-fill, and --bg-max, you can use --geometry to spec‐
580 ify an offset from one side of the screen instead of centering the image.
581 Positive values will offset from the left/top side, negative values from
582 the bottom/right. +0 and -0 are both valid and distinct values.
583 Note that all options except --bg-tile support Xinerama. For instance,
585 if you have multiple screens connected and use e.g. --bg-center, feh
586 will center or appropriately offset the image on each screen. You may
587 even specify more than one file, in that case, the first file is set on
588 screen 0, the second on screen 1, and so on.
589 Use --no-xinerama to treat the whole X display as one screen when setting
591 wallpapers. You may also use --xinerama-index to use feh as a background
592 setter for a specific screen.
593 --bg-center
595 Center the file on the background. If it is too small, it will
596 be surrounded by a border as specified by --image-bg.
597 --bg-fill
599 Like --bg-scale, but preserves aspect ratio by zooming the image
600 until it fits. Either a horizontal or a vertical part of the
601 image will be cut off
602 --bg-max
604 Like --bg-fill, but scale the image to the maximum size that fits
605 the screen with borders on one side. The border color can be set
606 using --image-bg.
607 --bg-scale
609 Fit the file into the background without repeating it, cutting
610 off stuff or using borders. But the aspect ratio is not pre‐
611 served either
612 --bg-tile
614 Tile (repeat) the image in case it is too small for the screen
615 --no-fehbg
617 Do not write a ~/.fehbg file
618
620 %f Image path/filename
621 %F Escaped image path/filename (for use in shell commands)
623 %g w,h window dimensions in pixels (mnemonic: geometry)
625 %h Image height
627 %l Total number of files in filelist
629 %L Temporary copy of filelist. Multiple uses of %L within the same
631 format string will return the same copy.
632 %m Current mode
634 %n Image name
636 %N Escaped image name
638 %o x,y offset of top-left image corner to window corner in pixels
640 %p Number of image pixels

665 %% A literal %
667
669 feh has three config files: themes for theme definitions, keys for key
670 bindings and buttons for mouse button bindings. It will try to read them
671 from $XDG_CONFIG_HOME/feh/, which (when XDG_CONFIG_HOME is unset)
672 defaults to ~/.config/feh/. If the files are not found in that direc‐
673 tory, it will also try /etc/feh/.
674 All config files treat lines starting with a "#" character as comments.
676 Comments at the end of a line are not supported.
677
679 .config/feh/themes allows the naming of option groups, called themes.
680 It takes entries of the form "theme options ...", where theme is the name
682 of the entry and options are the options which will be applied when the
683 theme is used.
684 Note that the option parser does not behave like a normal shell: filename
686 expansion and backslash escape sequences are not supported and passed to
687 feh's option parser as-is. However, quoting of arguments is respected
688 and can be used for arguments with whitespace. So, the sequence "--info
689 "foo bar"" works as intended (that is, it display the string "foo bar"),
690 whereas the option string "--info foo\ bar" will only display "foo\" and
691 complain about the file bar not existing. Please keep this in mind when
692 writing theme files.
693 An example entry is "imagemap -rVq --thumb-width 40 --thumb-height 30
695 --index-info '%n\n%wx%h'".
696 You can use this theme in two ways. Either call "feh -Timagemap *.jpg",
698 or create a symbolic link to feh with the name of the theme you want it
699 to use. For the example above, this would be "ln -s `which feh `
700 ~/bin/imagemap". Now just run "imagemap *.jpg" to use these options.
701 Note that you can split a theme over several lines by placing a backslash
703 at the end of an unfinished line. A single option-argument-pair must not
704 span multiple lines. A single line must not be longer than 1023 charac‐
705 ters, but there's no upper limit for the length of a theme.
706 Command line options always override theme options.
708
710 .config/feh/keys defines key bindings. It has entries of the form
711 "action [key1 [key2 [key3]]]".
712 Each key is an X11 keysym name as shown by xev(1), like "Delete". It may
714 optionally start with modifiers for things like Control, in which case
715 key looks like mod-keysym (for example "C-Delete" for Ctrl+Delete or
716 "C-1-Delete" for Ctrl+Alt+Delete)
717 Available modifiers are C for Control, S for Shift and 1, 4 for Mod1 and
719 Mod4. To match an uppercase letter like "S" instead of "s", the Shift
720 modifier is not required.
721 Specifying an action without any keys unbinds it (i.e. the default bind‐
723 ings are removed).
724 Note: Do not use the same keybinding for multiple actions. When binding
726 an action to a new key (or mouse button), make sure to unbind it from its
727 previous action, if present. feh does not check for conflicting bind‐
728 ings, so their behaviour is undefined.
729 For a list of the action names, see KEYS. Note that not all of the key
731 names used there correspond to X11 keysyms. Most notably, page up (Prior
732 / Page_Up), page down (Next / Page_Down) and the keypad keys (KP_*) do
733 not.
734
736 The following actions and default key bindings can be used in an image
737 window. (The strings in [square brackets] are the config action names).
738 If feh is running inside a terminal and its standard input is not used
739 for images or filelists, key input from the terminal is also accepted.
740 However, terminal input support is currently limited to most alphanumeric
741 characters (0-9 a-z A-Z and some more), arrow keys, return and backspace.
742 The Alt (Mod1) modifier is also supported.
743 a [toggle_actions]
745 Toggle actions display (see --draw-actions)
746 A [toggle_aliasing]
748 Enable/Disable anti-aliasing
749 c [toggle_caption]
751 Caption entry mode. If --caption-path has been specified, then
752 this enables caption editing. The caption at the bottom of the
753 screen will turn yellow and can be edited. Hit return to confirm
754 and save the caption, or escape to cancel editing. Note that you
755 can insert an actual newline into the caption using
756 ⟨Ctrl+return⟩.
757 d [toggle_filenames]
759 Toggle filename display (see --draw-filename)
760 e [toggle_exif]
762 (optional feature, enabled in this build) Toggle EXIF tag display

772 automatically change slides based on --slideshow-delay.
773 i [toggle_info]
775 Toggle info display (see --info)
776 k [toggle_keep_vp]
778 Toggle zoom and viewport keeping. When enabled, feh will keep

795 Show previous image. Selects the previous image in thumbnail
796 mode.
797 q, ⟨Escape⟩ [quit]
799 Quit feh
800 r [reload_image]
802 Reload current image. Useful for webcams
803 s [save_image]
805 Save the current image as "feh_PID_ID_FILENAME"
806 w [size_to_image]
808 Change window size to fit current image size (plus/minus zoom, if
809 set). In scale-down and fixed-geometry mode, this also updates
810 the window size limits.
811 x [close]
813 Close current window
814 z [jump_random]
816 Jump to a random position in the current filelist
817 Z [toggle_auto_zoom]
819 Toggle auto-zoom.
820 [, ] [prev_dir, next_dir]
822 Jump to the first image of the previous or next sequence of
823 images sharing a directory name in the current filelist. Use
824 --sort dirname if you would like to ensure that all images in a
825 directory are grouped together.
826 <, > [orient_3, orient_1]
828 rotate the image 90 degrees (counter)clockwise.
829 When --edit is used, this also rotates the image in the underly‐
831 ing file. Rotation is lossless, but may create artifacts in some
832 image corners when used with JPEG images. Rotating in the
833 reverse direction will make them go away. See jpegtran(1) for
834 more about lossless JPEG rotation. Note: feh assumes that this
835 feature is used to normalize image orientation. For JPEG images,
836 it will unconditionally set the EXIF orientation tag to 1 ("0,0
837 is top left") after every rotation. See jpegexiforient(1) for
838 details on how to change this flag.
839 _ [flip]
841 Vertically flip image. When --edit is used, this also flips the
842 image in the underlying file (see above).
843 | [mirror]
845 Horizontally flip image. When --edit is used, this also flips
846 the image in the underlying file (see above).
847 0 .. 9 [action_0 .. action_9]

868 Increase reload delay by 1 second
869 - [reload_minus]
871 Decrease reload delay by 1 second
872 ⟨Delete⟩ [remove]
874 Remove current file from filelist
875 ⟨Ctrl+Delete⟩ [delete]
877 Remove current file from filelist and delete it
878 ⟨keypad Left⟩, ⟨Ctrl+Left⟩ [scroll_left]

881 ⟨keypad Right⟩, ⟨Ctrl+Right⟩ [scroll_right]
883 Scroll to the right
884 ⟨keypad up⟩, ⟨Ctrl+Up⟩ [scroll_up]
886 Scroll up
887 ⟨keypad Down⟩, ⟨Ctrl+Down⟩ [scroll_down]
889 Scroll down. Note that the scroll keys work without anti-alias‐
890 ing for performance reasons; hit the render key after scrolling
891 to anti-alias the image.
892 ⟨Alt+Left [scroll_left_page]⟩
894 Scroll to the left by one page
895 ⟨Alt+Right [scroll_right_page]⟩

906 Anti-alias the image. Opens the currently selected image in
907 thumbnail mode.
908 ⟨keypad +⟩, ⟨Up⟩ [zoom_in]
910 Zoom in
911 ⟨keypad -⟩, ⟨Down⟩ [zoom_out]
913 Zoom out
914 *, ⟨keypad *⟩ [zoom_default]
916 Zoom to 100%
917 /, ⟨keypad /⟩ [zoom_fit]
919 Zoom to fit the window size
920 ! [zoom_fill]
922 Zoom to fill the window size like --bg-fill
923 MENU KEYS
925 The following keys bindings are used for the feh menu:
926 ⟨Escape⟩ [menu_close]
928 Close the menu
929 ⟨Up⟩ [menu_up]
931 Highlight previous menu item
932 ⟨Down⟩ [menu_down]
934 Highlight next menu item
935 ⟨Left⟩ [menu_parent]
937 Highlight parent menu item
938 ⟨Right⟩ [menu_child]
940 Highlight child menu item
941 ⟨Return⟩, ⟨space⟩ [menu_select]
943 Select highlighted menu item
944
946 .config/feh/buttons. This works like the keys config file: the entries
947 are of the form "action [binding]".
948 Each binding is a button number. It may optionally start with modifiers
950 for things like Control, in which case binding looks like mod-button (for
951 example C-1 for Ctrl + Left button).
952 Note: Do not use the same button for multiple actions. feh does not
954 check for conflicting bindings, so their behaviour is undefined. Either
955 unbind the unwanted action, or bind it to another unused button. The
956 order in which you bind / unbind does not matter, though.
957 For the available modifiers, see KEYS CONFIGURATION SYNTAX.
959 BUTTONS
961 In an image window, the following buttons may be used (The strings in
962 [square brackets] are the config action names). Additionally, all
963 actions specified in the KEYS section can also be bound to a button.
964 unbound [reload]
966 Reload current image
967 1 ⟨left mouse button⟩ [pan]
969 pan the current image
970 2 ⟨middle mouse button⟩ [zoom]
972 Zoom the current image
973 3 ⟨right mouse button⟩ [toggle_menu]
975 Toggle menu
976 4 ⟨mousewheel down⟩ [prev_img]
978 Show previous image
979 5 ⟨mousewheel up⟩ [next_img]
981 Show next image
982 Ctrl+1 [blur]
984 Blur current image
985 Ctrl+2 [rotate]
987 Rotate current image
988 unbound [zoom_in]
990 Zoom in
991 unbound [zoom_out]
993 Zoom out
994
996 Default Bindings: When viewing an image, mouse button 1 pans the image
997 (moves it around) or, when only clicked, moves to the next image
998 (slideshow mode only). Quick drags with less than 2px of movement per
999 axis will be treated as clicks to aid graphics tablet users. Mouse but‐
1000 ton 2 zooms (click and drag left->right to zoom in, right->left to zoom
1001 out, click once to restore zoom to 100%) and mouse button 3 opens the
1002 menu.
1003 Ctrl+Button 1 blurs or sharpens the image (drag left to blur, right to
1005 sharpen); Ctrl+Button 2 rotates the image around the center point.
1006 A note about pan and zoom modes: In pan mode, if you reach a window bor‐
1008 der but haven't yet panned to the end of the image, feh will warp your
1009 cursor to the opposite border so you can continue panning.
1010 When clicking the zoom button and immediately releasing it, the image
1012 will be back at 100% zoom. When clicking it and moving the mouse while
1013 holding the button down, the zoom will be continued at the previous zoom
1014 level. The zoom will always happen so that the pixel on which you
1015 entered the zoom mode remains stationary. So, to enlarge a specific part
1016 of an image, click the zoom button on that part.
1017
1019 In slideshow mode, feh handles the following signals:
1020 SIGUSR1
1022 Switch to next image
1023 SIGUSR2
1025 Switch to previous image
1026
1028 Here are some examples of useful option combinations. See also:
1029 ⟨https://feh.finalrewind.org/examples/⟩
1030 feh ~/Pictures
1032 Show all images in ~/Pictures
1033 feh -r ~/Pictures
1035 Recursively show all images found in ~/Pictures and subdirecto‐
1036 ries
1037 feh -rSfilename --version-sort ~/Pictures
1039 Same as above, but sort naturally. By default, feh will show
1040 files in the string order of their names, meaning e.g. "foo
1041 10.jpg" will come before "foo 2.jpg". In this case, they are
1042 instead ordered as a human would expect.
1043 feh -t -Sfilename -E 128 -y 128 -W 1024 ~/Pictures
1045 Show 128x128 pixel thumbnails, limit window width to 1024 pixels.
1046 feh -t -Sfilename -E 128 -y 128 -W 1024 -P -C
1048 /usr/share/fonts/truetype/ttf-dejavu/ -e DejaVuSans/8 ~/Pictures
1049 Same as above, but enable thumbnail caching and use a smaller
1050 font.
1051 feh -irFarial/14 -O index.jpg ~/Pictures
1053 Make an index print of ~/Pictures and all directories below it,
1054 using 14 point Arial to write the image info under each thumb‐
1055 nail. Save the image as index.jpg and don't display it, just
1056 exit. Note that this even works without a running X server
1057 feh --unloadable -r ~/Pictures
1059 Print all unloadable images in ~/Pictures, recursively
1060 feh -f by_width -S width --reverse --list .
1062 Write a list of all images in the directory to by_width, sorted
1063 by width (widest images first)
1064 feh -w ~/Pictures/holidays
1066 Open each image in ~/Pictures/holidays in its own window
1067 feh -FD5 -Sname ~/Pictures/presentation
1069 Show the images in .../presentation, sorted by name, in
1070 fullscreen, automatically change to the next image after 5 sec‐
1071 onds
1072 feh -rSwidth -A "mv %F ~/images/%N" ~/Pictures
1074 View all images in ~/Pictures and below, sorted by width, move an
1075 image to ~/image/image_name when enter is pressed
1076 feh --start-at ~/Pictures/foo.jpg
1078 View all images in ~/Pictures, starting with foo.jpg. All other
1079 images are still in the slideshow and can be viewed normally
1080 feh --start-at ~/Pictures/foo.jpg ~/Pictures
1082 Same as above.
1083 feh --info "exifgrep '(Model|DateTimeOriginal|FNumber|ISO|Flash)' %F |
1085 cut -d . -f 4-" .
1086 Show some EXIF information, extracted by exifprobe/exifgrep
1087 feh --action 'rm %F' -rl --max-dimension 1000x800
1089 Recursively remove all images with dimensions below or equal to
1090 1000x800 pixels from the current directory.
1091 feh -L '%w %h %f' | awk '{ if ($1 > $2) { print $0 } }' | cut -d ' ' -f
1093 3- | feh -f -
1094 Show landscape pictures (image width greater than height) in the
1095 current directory.
1096
1098 When --edit is used, feh needs the jpegtran and jpegexiforient binaries
1099 (usually distributed in "libjpeg-progs" or similar) for lossless JPEG
1100 rotation.
1101 To view images from URLs such as "http://", feh must be compiled with
1103 libcurl support. It is enabled in this build
1104
1106 On systems with giflib 5.1.2, feh may be unable to load gif images. For
1107 affected mips, mipsel and arm devices, gif support is completely broken,
1108 while on x86 / x86_64 gifs can usually only be loaded if they are the
1109 first image in the filelist. This appears to be a bug in giflib, see
1110 ⟨https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813729⟩ for details.
1111 Workaround: Use --conversion-timeout 5 (or some other positive value) to
1112 load gifs with imagemagick instead, or downgrade to giflib 5.1.1, or
1113 upgrade to giflib 5.1.4.
1114 While loading images using libcurl, feh will not react to key or mouse
1116 actions.
1117 Thumbnail mode is somewhat inefficient, and because of that not nearly as
1119 fast as it could be.
1120 --scale-down does not take window decorations into account and may there‐
1122 fore make the window slightly too large.
