\f[B]osmium apply\-changes\f[] [\f[I]OPTIONS\f[]]
\f[I]OSM\-DATA\-FILE\f[] \f[I]OSM\-CHANGE\-FILE\f[]...

\f[I]OSM\-HISTORY\-FILE\f[] \f[I]OSM\-CHANGE\-FILE\f[]...
.SH DESCRIPTION
.PP
Merges the content of all OSM change files and applies those changes to
the OSM data or history file.
.PP
Objects in the data or historyy file must be sorted by type, ID, and
version.
Objects in change files need not be sorted, so it doesn\[aq]t matter in
what order the change files are given or in what order they contain the
data.
.PP
Changes can be applied to normal OSM data files or OSM history files
with this command.
File formats will be autodetected from the file name suffixes, see the
\f[B]\-\-with\-history\f[] option if that doesn\[aq]t work.
.SH OPTIONS
.TP
.B \-r, \-\-remove\-deleted
Deprecated.
Remove deleted objects from the output.
This is now the default if your input file is a normal OSM data file
(\[aq].osm\[aq]).
.RS
.RE
.TP
.B \-s, \-\-simplify
Deprecated.
Only write the last version of any object to the output.
This is now the default if your input file is a normal OSM data file
(\[aq].osm\[aq]).
.RS
.RE
.TP
.B \-\-with\-history
Update an OSM history file (instead of a normal OSM data file).
Both input and output must be history files.
This option is usually not necessary, because history files will be
detected from their file name suffixes, but if this detection
doesn\[aq]t work, you can force this mode with this option.

.RE
.SH INPUT OPTIONS
.TP
.B \-F, \-\-input\-format=FORMAT
The format of the input file(s).
Can be used to set the input format if it can\[aq]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 \f[B]osmium\-file\-formats\f[](5) or the libosmium manual for
details.
.RS
.RE
.SH OUTPUT OPTIONS
.TP
.B \-f, \-\-output\-format=FORMAT
The format of the output file.
Can be used to set the output file format if it can\[aq]t be

See \f[B]osmium\-file\-formats\f[](5) or the libosmium manual for
details.
.RS
.RE
.TP
.B \-\-fsync
Call fsync after writing the output file to force flushing buffers to
disk.
.RS
.RE
.TP
.B \-\-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 "\f[I]osmium/\f[]" and the version of osmium.
.RS
.RE
.TP
.B \-o, \-\-output=FILE
Name of the output file.
Default is \[aq]\-\[aq] (STDOUT).
.RS

This option can be given several times.
See the \f[I]libosmium manual\f[] for a list of allowed header options.

.SH DIAGNOSTICS
.PP
\f[B]osmium apply\-changes\f[] exits with exit code
.TP
.B 0
if everything went alright,
.RS
.RE
.TP
.B 1
if there was an error processing the data, or
.RS
.RE
.TP
.B 2
if there was a problem with the command line arguments.
.RS
.RE
.SH MEMORY USAGE
.PP
\f[B]osmium apply\-changes\f[] keeps the contents of all the change
files in main memory.
This will take roughly 10 times as much memory as the files take on disk
in \f[I]\&.osm.bz2\f[] format.
.SH EXAMPLES
.PP
Apply changes in \f[C]362.osc.gz\f[] to planet file and write result to
\f[C]new.osm.pbf\f[]:
.IP
.nf
\f[C]
osmium\ apply\-changes\ \-\-output=new.osm.pbf\ planet.osm.pbf\ 362.osc.gz
\f[]
