## 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]...

| 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

| Input file syntax:

| −P, −−properties−input

| input file is in Java .properties syntax

| −−stringtable−input

| input file is in NeXTstep/GNUstep .strings syntax

| Output details:

| −−color

| use colors and other text attributes always

| −−color=WHEN

| use colors and other text attributes if WHEN. WHEN may be ’always’, ’never’, ’auto’, or ’html’.

| −−style=STYLEFILE

| specify CSS style rule file for −−color

| −−no−escape

| do not use C escapes in output (default)

| −−escape

| use C escapes in output, no extended chars

| −−force−po

| write PO file even if empty

| −−indent

| indented output style

| −−no−location

| suppress ’#: filename:line’ lines

| −−add−location

| preserve ’#: filename:line’ lines (default)

| −−strict

| strict Uniforum output style

| −p, −−properties−output

| write out a Java .properties file

| −−stringtable−output

| write out a NeXTstep/GNUstep .strings file

| −w, −−width=NUMBER

| set output page width

| −−no−wrap

| do not break long message lines, longer than the output page width, into several lines

| −−sort−output

| generate sorted output

| −−sort−by−file

| sort output by file location

| Informative output:

| −h, −−help

| display this help and exit
