How to grep the exact name?

Hi All

Here is one o/p from a program I have ...

Can someone tell me the way so that I get only the output by the user "li" not the other users which have "li" in the name.

Surely I dont like the idea

Thanks a lot to all in advance

p4 users | grep "\<li\>"
 Thats cool !!! Thanks 

You could also try "grep -w"......this looks for whole words
