NAME

       osmium-cat - concatenate OSM files and convert to different formats

SYNOPSIS

       osmium cat [OPTIONS] INPUT-FILE...

DESCRIPTION

       Concatenates all input files and writes the result to the output file.  The data is not sorted in any way
       but strictly copied from input to output.

       Because  this  program supports several different input and output formats, it can be used to convert OSM
       files from one format into another.

OPTIONS

       -f, --output-format=FORMAT
              The format of the output file.  Can be used  to  set  the  output  file  format  if  it  can't  be
              autodetected  from  the  output file name.  See osmium-file-formats(5) or the libosmium manual for
              details.

       -F, --input-format=FORMAT
              The format of the input files.  Can be used to set the input format if it  can't  be  autodetected
              from  the  file  names.   This will set the format for all input files, there is no way to set the
              format for some input files only.  See osmium-file-formats(5) or the libosmium manual for details.

       --generator=NAME
              The name and version of the program generating the output file.  It will be added to the header of
              the output file.  Default is "osmium/" and the version of osmium.

       -o, --output=FILE
              Name of the output file.  Default is '-' (stdout).

       -O, --overwrite
              Allow an existing output file to be overwritten.  Normally osmium will refuse  to  write  over  an
              existing file.

       --fsync
              Call fsync after writing the output file to force the OS to flush buffers to disk.

       --output-header=OPTION
              Add output header option.  This option can be given several times.  See the libosmium manual for a
              list of allowed header options.

       -t, --object-type=TYPE
              Read  only objects of given type (node, way, relation, changeset).  By default all types are read.
              This option can be given multiple times.

       -v, --verbose
              Set verbose mode.  The program will output information about what it is doing to stderr.

DIAGNOSTICS

       osmium cat exits with exit code

       0      if everything went alright,

       1      if there was an error processing the data, or

       2      if there was a problem with the command line arguments.

EXAMPLES

       Convert a PBF file to a compressed XML file:

              osmium cat -o out.osm.bz2 in.osm.pbf

       Concatenate all change files in the 'changes' directory into one:

              osmium cat -o all-changes.osc.gz changes/*.osc.gz

       Copy nodes and ways from source to destination file:

              osmium cat -o dest.osm.pbf source.osm.pbf -t node -t way
