6 osmium-cat - concatenate OSM files and convert to different formats
7
9 osmium cat [OPTIONS] OSM-FILE...
10
12 Concatenates all input files and writes the result to the output file.
13 The data is not sorted in any way but strictly copied from input to
14 output.
15 Because this program supports several different input and output for‐
17 mats, it can be used to convert OSM files from one format into another.
18 This commands reads its input file(s) only once and writes its output
20 file in one go so it can be streamed, ie. it can read from STDIN and
21 write to STDOUT.
22
24 -t, –object-type=TYPE
25 Read only objects of given type (node, way, relation, change‐
26 set). By default all types are read. This option can be given
27 multiple times.
28
30 -h, –help
31 Show usage help.
32 -v, –verbose
34 Set verbose mode. The program will output information about
35 what it is doing to STDERR.
36 –progress
38 Show progress bar. Usually a progress bar is only displayed if
39 STDOUT and STDERR are detected to be TTY. With this option a
40 progress bar is always shown. Note that a progress bar will
41 never be shown when reading from STDIN or a pipe.
42 –no-progress
44 Do not show progress bar. Usually a progress bar is displayed
45 if STDOUT and STDERR are detected to be a TTY. With this option
46 the progress bar is suppressed. Note that a progress bar will
47 never be shown when reading from STDIN or a pipe.
48
50 -F, –input-format=FORMAT
51 The format of the input file(s). Can be used to set the input
52 format if it can't be autodetected from the file name(s). This
53 will set the format for all input files, there is no way to set
54 the format for some input files only. See osmium-file-for‐
55 mats(5) or the libosmium manual for details.
56
58 -f, –output-format=FORMAT
59 The format of the output file. Can be used to set the output
60 file format if it can't be autodetected from the output file
61 name. See osmium-file-formats(5) or the libosmium manual for
62 details.
63 –fsync Call fsync after writing the output file to force flushing buf‐
65 fers to disk.
66 –generator=NAME
68 The name and version of the program generating the output file.
69 It will be added to the header of the output file. Default is
70 “osmium/” and the version of osmium.
71 -o, –output=FILE
73 Name of the output file. Default is `-' (STDOUT).
74 -O, –overwrite
76 Allow an existing output file to be overwritten. Normally
77 osmium will refuse to write over an existing file.
78 –output-header=OPTION=VALUE
80 Add output header option. This command line option can be used
81 multiple times for different OPTIONs. See the libosmium manual
82 for a list of available header options.
83
85 osmium cat exits with exit code
86 0 if everything went alright,
88 1 if there was an error processing the data, or
90 2 if there was a problem with the command line arguments.
92
94 osmium cat does all its work on the fly and doesn't keep much data in
95 main memory.
96
98 Convert a PBF file to a compressed XML file:
99 osmium cat -o out.osm.bz2 in.osm.pbf
101 Concatenate all change files in the `changes' directory into one:
103 osmium cat -o all-changes.osc.gz changes/*.osc.gz
105 Copy nodes and ways from source to destination file:
107 osmium cat -o dest.osm.pbf source.osm.pbf -t node -t way
