       msggrep - pattern matching on message catalog

SYNOPSIS

DESCRIPTION
       Extracts all messages of a translation catalog that match a given pattern or belong to some given source files.

       Mandatory arguments to long options are mandatory for short options too.

   Input file location:
       INPUTFILE
	      input PO file

       -D, --directory=DIRECTORY
	      add DIRECTORY to list for input files search

       If no input file is given or if it is -, standard input is read.

   Output file location:
       -o, --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 -.

   Message selection:
	      [-N  SOURCEFILE]...  [-M	DOMAINNAME]...	[-J MSGCTXT-PATTERN] [-K MSGID-PATTERN] [-T MSGSTR-PATTERN] [-C COM‐
	      MENT-PATTERN] [-X EXTRACTED-COMMENT-PATTERN]

       A message is selected if it comes from one of the specified source files, or if it comes from one  of  the  specified
       domains, or if -J is given and its context (msgctxt) matches MSGCTXT-PATTERN, or if -K is given and its key (msgid or
       msgid_plural)  matches MSGID-PATTERN, or if -T is given and its translation (msgstr) matches MSGSTR-PATTERN, or if -C
       is given and the translator's comment matches COMMENT-PATTERN, or if -X is given and the	 extracted  comment  matches
       EXTRACTED-COMMENT-PATTERN.

       When  more  than one selection criterion is specified, the set of selected messages is the union of the selected mes‐
       sages of each criterion.
