NAME

       msggrep - pattern matching on message catalog

SYNOPSIS

       msggrep [OPTION] [INPUTFILE]

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 COMMENT-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 messages of each criterion.

       MSGCTXT-PATTERN or MSGID-PATTERN or MSGSTR-PATTERN or COMMENT-PATTERN or EXTRACTED-COMMENT-PATTERN syntax:

	      [-E | -F] [-e PATTERN | -f FILE]...
