MSGGREP

msggrep − pattern matching on message catalog

msggrep [OPTION] [INPUTFILE]

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]...

PATTERNs are basic regular expressions by default, or extended regular expressions if −E is given, or fixed strings if −F is given.

start of patterns for the msgid

−T, −−msgstr

start of patterns for the msgstr

−C, −−comment
