search for occurrences

[ciro25]

i ve got a file with 100 of text lines and many occurrences.
How can i search and display them all nummbered?

E,g:

1) bla bla bla
2) fortij nfhru
3)fhdgfhdiwe

P.s i do not want to get rid of them just output them and redirect them in another file.

There must be a way to do it without using sed or awk isn it?

Thnx

You can write a script using 'grep' and pipe the output to a text file--that is of course if you know what strings to search for ;)

This is what i mean...
Look at this please!!!

[ciro.ruggiero@unix ~]$ grep $USER xx | cat -n
1 USER=ciro.ruggiero
2 MAIL=/var/spool/mail/ciro.ruggiero
3 PATH=/u01/app/oracle/product/10.2.0/db_1/bin:/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/home/ciro.ruggiero/bin
4 PWD=/home/ciro.ruggiero
5 HOME=/home/ciro.ruggiero
6 LOGNAME=ciro.ruggiero

This is almost what i wanted...how do i put a bracket after the numbers?
eg:
1)
2)

also...if i want to get rid of line 3 completaly, how doi do
