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

- -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]…
PATTERNs are basic regular expressions by default, or extended regular expressions if -E is given, or fixed strings if -F is given.
- -N, *–location*=/SOURCEFILE/

- -M, *–domain*=/DOMAINNAME/
- select messages belonging to domain DOMAINNAME
- -J, –msgctxt
- start of patterns for the msgctxt

- -T, –msgstr
- start of patterns for the msgstr
- -C, –comment
- start of patterns for the translator’s comment
- -X, –extracted-comment
