Thanks guys. Both solutions work perfectly.

Another issue that I have.

I have a file:

Code:
[user@server tmp]$ cat list 
http-/0.0.0.0:8091-1
http-/0.0.0.0:8091-4
http-/0.0.0.0:8091-1
http-/0.0.0.0:8091-10
http-/0.0.0.0:8091-7
http-/0.0.0.0:8091-17
http-/0.0.0.0:8091-15

Now I want only unique strings to be returned.

Code:
[user@server tmp]$ cat list  | uniq
http-/0.0.0.0:8091-1
http-/0.0.0.0:8091-4
http-/0.0.0.0:8091-1
http-/0.0.0.0:8091-10
http-/0.0.0.0:8091-7
http-/0.0.0.0:8091-17
http-/0.0.0.0:8091-15


Any idea why the uniq command isnt working ? I am getting the string http-/0.0.0.0:8091-1 twice.
