msggrep - pattern matching on message catalog

2. SYNOPSIS

msggrep [OPTION] [INPUTFILE]

3. 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.

3.1. 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.

3.2. 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 -.

3.3. 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
        select messages extracted from SOURCEFILE
  • -M, --domain=DOMAINNAME
        select messages belonging to domain DOMAINNAME
  • -J, --msgctxt
        start of patterns for the msgctxt
  • -K, --msgid
        start of patterns for the msgid
  • -T, --msgstr
        start of patterns for the msgstr
  • -C, --comment
        start of patterns for the translator's comment
  • -X, --extracted-comment
        start of patterns for the extracted comment
  • -E, --extended-regexp
        PATTERN is an extended regular expression
  • -F, --fixed-strings
        PATTERN is a set of newline-separated strings
  • -e, --regexp=PATTERN
        use PATTERN as a regular expression
  • -f, --file=FILE
        obtain PATTERN from FILE
  • -i, --ignore-case
        ignore case distinctions
  • -v, --invert-match
        output only the messages that do not match any selection criterion
