9 grim [options...] [output-file]
10
12 grim is a command-line utility to take screenshots of Wayland desktops.
13 For now it requires support for the screencopy protocol to work. Sup‐
14 port for the xdg-output protocol is optional, but improves fractional
15 scaling support.
16
17 grim will write an image to output-file, or to a timestamped file name
18 in $GRIM_DEFAULT_DIR if not specified. If $GRIM_DEFAULT_DIR is not set,
19 it falls back first to $XDG_PICTURES_DIR and then to the current work‐
20 ing directory. If output-file is -, grim will write the image to the
21 standard output instead.
22
24 -h
25 Show help message and quit.
26
27 -s <factor>
28 Set the output image's scale factor to factor. By default, the
29 scale factor is set to the highest of all outputs.
30
31 -g "<x>,<y> <width>x<height>"
32 Set the region to capture, in layout coordinates.
33
34 If set to -, read the region from the standard input instead.
35
36 -t <type>
37 Set the output image's file format to type. By default, the file‐
38 type is set to png, valid values are png, jpeg or ppm.
39
40 -q <quality>
41 Set the output jpeg's filetype compression rate to quality. By de‐
42 fault, the jpeg quality is 80, valid values are between 0-100.
43
44 -l <level>
45 Set the output PNG's filetype compression level to level. By de‐
46 fault, the PNG compression level is 6 on a scale from 0 to 9. Level
47 9 gives the highest compression ratio, but may be slow; level 1
48 gives a lower compression ratio, but is faster. Level 0 does no
49 compression at all, and produces very large files; it can be useful
50 when grim is used in a pipeline with other commands.
51
52 -o <output>
53 Set the output name to capture.
54
55 -c
56 Include cursors in the screenshot.
