NAME
       msggrep - pattern matching on message catalog
SYNOPSIS
       msggrep [OPTION] [INPUTFILE]
DESCRIPTION
       Extracts  all messages of a translation catalog that match a given pat-
       tern 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 speci-
       fied 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-PAT-
       TERN.
       When  more  than  one  selection  criterion  is  specified,  the set of
       selected messages is the union of the selected messages of each  crite-
       rion.
       MSGCTXT-PATTERN  or  MSGID-PATTERN or MSGSTR-PATTERN or COMMENT-PATTERN
