msgmerge – merge message catalog and template
msgmerge [OPTION] def.po ref.pot
Merges two Uniforum style .po files together. The def.po file is an
existing PO file with translations which will be taken over to the
newly created file as long as they still match; comments will be pre‐
served, but extracted comments and file positions will be discarded.
The ref.pot file is the last created PO file with up-to-date source
references but old translations, or a PO Template file (generally cre‐
ated by xgettext); any translations or comments in the file will be
discarded, however dot comments and file positions will be preserved.
Where an exact match cannot be found, fuzzy matching is used to produce
Mandatory arguments to long options are mandatory for short options
