regular expression help ?

smcelhinney

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.
