# msgcomm

## NAME



           msgcomm - match two message catalogs
    


## SYNOPSIS



           **msgcomm**[_OPTION_] [_INPUTFILE_]...
    


## DESCRIPTION



           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 too.
