Usage: prgrp [options] regex format file1 file2 ... filen regex: A POSIX.2 regex(7) regular expression format: A string with which to format the output of regex. options: -i ignore case -N default parameter, where N is between 1 and 9 format string looks like this: "First parameter: $1, third parameter $3, second parameter $2" What do you think?
