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.  (Unless  the  multipass
       strategy is used.)

OPTIONS

       -s, --strategy=STRATEGY
              Sorting  strategy.   The  “simple” strategy reads all input files into memory, does
              the sorting and writes everything out.  The “multipass” strategy  reads  the  input
              files  in  three passes, one for nodes, one for ways, and one for relations.  After
              reading all objects of each type, they are sorted and written out.  This is  a  bit
              slower  than  the  “simple”  strategy,  but uses less memory.  The “multi” strategy
              doesn’t work when reading from STDIN.  Default: “simple”.

COMMON OPTIONS

       -h, --help
              Show usage help.

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

       --progress
              Show  progress  bar.  Usually a progress bar is only displayed if STDOUT and STDERR
              are detected to be TTY.  With this option a progress bar  is  always  shown.   Note
              that a progress bar will never be shown when reading from STDIN or a pipe.

       --no-progress
              Do not show progress bar.  Usually a progress bar is displayed if STDOUT and STDERR
              are detected to be a TTY.  With this option the progress bar is  suppressed.   Note
              that a progress bar will never be shown when reading from STDIN or a pipe.

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=VALUE
              Add output header option.  This command line option can be used multiple times  for
              different  OPTIONs.   See  the  libosmium  manual  for  a  list of available header
              options.  For some commands you can use  the  special  format  “OPTION!”  (ie.   an
              exclamation mark after the OPTION and no value set) to set the value to the same as
              in the input file.

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
