It depends how you wish to obtain the details.

Do you wish to get the line number by looking up a given nickname?

or get a nickname aby giving a line number?

Ok, let's say i have a filename that consists of nicknames and hostnames like this:

nick host
nick host
etc.

How can i get a specific line number from the file, and the matching nick. For example, get the first word (=nick) on line 3.
