NAME
       osmium-merge-changes - merge several OSM change files into one


SYNOPSIS
       osmium merge-changes [OPTIONS] CHANGE-FILE...


DESCRIPTION
       Merges  the  content  of  all change files given on the command line into one large change
       file.  Objects are sorted by type, ID, and version, so it doesn't matter in what order the
       change files are given or in what order they contain the data.

       osmium merge does its work in main memory, so all data has to fit in there!


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).

       --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.

       -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.

       -s, --simplify
              Only write the last version of any object to the output.

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


DIAGNOSTICS
       osmium merge-changes 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
       Merge all changes in changes directory into all.osc.gz:

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

       Because osmium merge-changes sorts its input, you can also use it to sort  just  a  single
       change file:

              osmium merge-changes unsorted.osc.gz -o sorted.osc.gz
