NAME

       osmium-sort - sort OSM files

SYNOPSIS

       osmium sort [OPTIONS] OSM-FILE...

DESCRIPTION

       Combines and sorts the content of all input files given on the command line.

       Objects  are  sorted  by  type,  ID, and version.  IDs are sorted negative IDs first, then
       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.  If there are several objects of the same type and with the same ID and
       version the sort order is unspecified.  Duplicate objects will not be removed.

       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 “multipass”  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  osmium-output-headers(5)  man  page  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
