NAME

       osmium-sort - sort OSM files

SYNOPSIS

       osmium sort [OPTIONS] OSM-FILE...

DESCRIPTION

       Merges the content of all input files given on the command line and sort the result.

       Objects  are  sorted by type, ID, and version.  IDs are sorted negative IDs first, the positive IDs, both
       ordered by their absolute values.  So the sort order for types and IDs is:

       node -1, node -2, ..., node 1, node 2, ..., way -1, way -2, ..., way 1, way 2, ..., relation -1, relation
       -2, ..., relation 1, relation 2, ...

       If there are several objects of the same type and with the same ID they are ordered by ascending version.

       This command works with normal OSM data files, history files, and change files.

       This commands reads its input file(s) only once and writes its output  file  in  one  go  so  it  can  be
       streamed, ie.  it can read from STDIN and write to STDOUT.

COMMON OPTIONS

       -h, --help
              Show usage help.

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

INPUT OPTIONS

       -F, --input-format=FORMAT
              The  format of the input file(s).  Can be used to set the input format if it can't be autodetected
              from the file name(s).  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.

OUTPUT 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.

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

       --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.

       --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.

DIAGNOSTICS

       osmium sort 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.

MEMORY USAGE

       osmium sort keeps the contents of all the input files in main memory.  This will take roughly 10 times as
       much memory as the files take on disk in .osm.bz2 or osm.pbf format.

EXAMPLES

       Sort in.osm.bz2 and write out to sorted.osm.pbf:

              osmium sort -o sorted.osm.pbf in.osm.bz2
