In the text file each line has a userhost:
screenname[12345678_12345678@1.2.3.4]
Convert to hash table format:
screenname screenname[12345678_12345678@1.2.3.4]
This way I can search the hash table by screenname (item) to get all the userhosts (data) that use that screenname.
Though I'm a lil' bit confused as to how to use the host from each of those screenname's (item) userhost (data) and search the hash table for all the screennames that use that host. Like a reverse lookup.
