msgcat Man page



msgcat – combines several message catalogs




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 mes‐
sages 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, com‐
ments, 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
