[TEXTDOMAIN] MSGID

retrieve translated message corresponding to MSGID from TEXTDOMAIN

If the TEXTDOMAIN parameter is not given, the domain is determined from the environment variable TEXTDOMAIN. If the message catalog is not found in the regular directory, another location can be specified with the environment variable TEXTDOMAINDIR. When used with the -s option the program behaves like the `echo' command. But it does not simply copy its arguments to stdout. Instead those messages found in the selected catalog are translated. Standard search directory: /usr/share/locale
