9.6 Invoking the 'msgcomm' Program
==================================
msgcomm [OPTION] [INPUTFILE]...
The 'msgcomm' program finds messages which are common to two or more
of the specified PO files. By using the '--more-than' option, greater
commonality may be requested before messages are printed. Conversely,
the '--less-than' option may be used to specify less commonality before
messages are printed (i.e. '--less-than=2' will only print the unique
messages). Translations, comments and extracted comments will be
preserved, but only from the first PO file to define them. File
positions from all PO files will be cumulated.
9.6.1 Input file location
-------------------------
'INPUTFILE ...'
Input files.
'-f FILE'
'--files-from=FILE'
Read the names of the input files from FILE instead of getting them
from the command line.
'-D DIRECTORY'
'--directory=DIRECTORY'
Add DIRECTORY to the list of directories. Source files are
searched relative to this list of directories. The resulting '.po'
file will be written relative to the current directory, though.
If INPUTFILE is '-', standard input is read.
9.6.2 Output file location
--------------------------
'-o FILE'
'--output-file=FILE'
Write output to specified file.
The results are written to standard output if no output file is
specified or if it is '-'.
9.6.3 Message selection
-----------------------
'-< NUMBER'
'--less-than=NUMBER'
Print messages with less than NUMBER definitions, defaults to
infinite if not set.
'-> NUMBER'
'--more-than=NUMBER'
Print messages with more than NUMBER definitions, defaults to 1 if
not set.
'-u'
'--unique'
Shorthand for '--less-than=2'. Requests that only unique messages
be printed.
9.6.4 Input file syntax
-----------------------
'-P'
'--properties-input'
Assume the input files are Java ResourceBundles in Java
'.properties' syntax, not in PO file syntax.
'--stringtable-input'
Assume the input files are NeXTstep/GNUstep localized resource
files in '.strings' syntax, not in PO file syntax.
9.6.5 Output details
--------------------
'--color'
'--color=WHEN'
Specify whether or when to use colors and other text attributes.
See *note The --color option:: for details.
'--style=STYLE_FILE'
Specify the CSS style rule file to use for '--color'. See *note
The --style option:: for details.
'--force-po'
Always write an output file even if it contains no message.
'-i'
'--indent'
Write the .po file using indented style.
'--no-location'
Do not write '#: FILENAME:LINE' lines.
'-n'
'--add-location=TYPE'
Generate '#: FILENAME:LINE' lines (default).
The optional TYPE can be either 'full', 'file', or 'never'. If it
is not given or 'full', it generates the lines with both file name
and line number. If it is 'file', the line number part is omitted.
If it is 'never', it completely suppresses the lines (same as
'--no-location').
'--strict'
Write out a strict Uniforum conforming PO file. Note that this
Uniforum format should be avoided because it doesn't support the
GNU extensions.
'-p'
'--properties-output'
Write out a Java ResourceBundle in Java '.properties' syntax. Note
that this file format doesn't support plural forms and silently
drops obsolete messages.
'--stringtable-output'
Write out a NeXTstep/GNUstep localized resource file in '.strings'
syntax. Note that this file format doesn't support plural forms.
'-w NUMBER'
'--width=NUMBER'
Set the output page width. Long strings in the output files will
be split across multiple lines in order to ensure that each line's
width (= number of screen columns) is less or equal to the given
NUMBER.
'--no-wrap'
Do not break long message lines. Message lines whose width exceeds
the output page width will not be split into several lines. Only
file reference lines which are wider than the output page width
will be split.
'-s'
'--sort-output'
Generate sorted output. Note that using this option makes it much
harder for the translator to understand each message's context.
'-F'
'--sort-by-file'
Sort output by file location.
'--omit-header'
Don't write header with 'msgid ""' entry.
9.6.6 Informative output
------------------------
'-h'
'--help'
Display this help and exit.
'-V'
'--version'
Output version information and exit.
