msgcomm Man page



msgcomm – match two message catalogs




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 and extracted comments will be preserved, but
only from the first PO file to define them. File positions from all PO
files will be cumulated.

Mandatory arguments to long options are mandatory for short options
