msgcat

Concatenate and merge multiple .po translation files. Useful in software localization pipelines to combine message catalogs with filtering options. More information: https://www.gnu.org/software/gettext/manual/html_node/msgcat-Invocation.html.

• Combine multiple .po files into one:

msgcat {{file1.po file2.po ...}} {{[-o|--output-file]}} {{combined.po}}

• Combine input files listed in a text file:

msgcat {{[-f|--files-from]}} {{path/to/file_list.txt}} {{[-o|--output-file]}} {{combined.po}}

• Set the output encoding (e.g. UTF-8):

msgcat {{[-t|--to-code]}} {{UTF-8}} {{input.po}} {{[-o|--output-file]}} {{output.po}}

• Output only unique messages (appearing in one file only):

msgcat {{[-u|--unique]}} {{file1.po file2.po ...}} {{[-o|--output-file]}} {{unique.po}}

• Use the first available translation for duplicate entries:

msgcat --use-first {{file1.po file2.po ...}} {{[-o|--output-file]}} {{output.po}}

• Display help:

msgcat {{[-h|--help]}}
