    Hi..

    Admitted, havent a clue. Im trying to check through a file which contains domain names, and I want to isolate three-letter .com domain names. Dont ask why, I've asked, and I havent got a proper answer yet.. : )

    Anyhow, Im using Textpad, so I can use regexp to search. But whats the string..

    is it something like

    s/[a-z]{3}/\.com/

    im talking through my arse now.. any ideas?

    I want to search for "abc.com" where abc is any combination of alphabetic-only characters. There's no preceding characters. the line starts with the domain name.

    Thanks
    Stephen

    The regular expression would be [a-zA-Z]{3}\.com
    I'm not sure what you need to wrap around it in textpad though

    Hate to be a know it all but if ya do this on a unix platform the command is simply

    grep "^:alnum:\{3\}\.com" filename.txt > results.out

    (change the figure in the command to determine the length of the required expression)




    Ps....1 hour please :):)

    Well unfortunately Textpad is only available for windows.
