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.
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.
−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 −.
[−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.
