that * isn't doing what you think it does. perl regexes are not shell
globs. it happens to work anyway since the tokens are unique
enough. read perlretut to learn perl regexes.
what have you tried so far? you know enough perl to get the array of
lines and loop over that. in english (or your native tongue), just
describe how you would do it to get to your goal. write it down. it is
only a few steps. then it will be easier to convert that to the perl
needed to accomplish it. if you then have more troubles, post your code
here and you will get help. a clue: you need a hash and its values will
be array references. read perlreftut, perllol and perldsc for more on
that.
