combines several message catalogs


msgcat [ OPTION ][ INPUTFILE ]...


Concatenates and merges the specified PO files. Find messages which are common to two or more of the specified PO files. By using the --more -than option, greater commonality may be requested before messages are printed. Conversely, the --less -than option may be used to specify less commonality before messages are printed (i.e. --less -than = 2 will only print the unique messages). Translations, comments, extracted comments, and file positions will be cumulated, except that if --use -first is specified, they will be taken from the first PO file to define them.

Mandatory arguments to long options are mandatory for short options too.

Input file location:

INPUTFILE ... input files

-f , --files -from = FILE get list of input files from FILE

-D , --directory = DIRECTORY add DIRECTORY to list for input files search

If input file 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:

-<, --less -than = NUMBER print messages with less than this many definitions, defaults to infinite if not set

->, --more -than = NUMBER print messages with more than this many definitions, defaults to 0 if not set

-u , --unique shorthand for --less -than = 2 ,requests that only unique messages be printed
