This time i found 2 little scripts that i wrote some time ago:
word.pl: this is a command line dictionary, it will connect to www.dictionary.com and parse the results.I find it very useful, you don't to load the browser :)
translate.pl: this one is almost the same that the other, but it will translate a word from english to spanish (you could change the language easy). This also run from command-line.
They are very useful, unless for me ;)
