/usr/bin/msgfilter

Usage: /usr/bin/msgfilter [OPTION] FILTER [FILTER-OPTION]

Applies a filter to all translations of a translation catalog.

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

Input file location:
  -i, --input=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 -.

The FILTER can be any program that reads a translation from standard input
and writes a modified translation to standard output.

Filter input and output:
  --newline                   add a newline at the end of input and
                                remove a newline from the end of output
Useful FILTER-OPTIONs when the FILTER is 'sed':
  -e, --expression=SCRIPT     add SCRIPT to the commands to be executed
  -f, --file=SCRIPTFILE       add the contents of SCRIPTFILE to the commands
                                to be executed
  -n, --quiet, --silent       suppress automatic printing of pattern space

Input file syntax:
  -P, --properties-input      input file is in Java .properties syntax
      --stringtable-input     input file is in NeXTstep/GNUstep .strings syntax
