grep exact letters

I used grep everyday. However, is there a parametes to grep an exact word. Let's say there is a word nelso, nels, nelson. If I grep "nels", it will show the three. Can I do a grep where it wil only display "nels" and not including nelson and nelso?

Use the word-boundry metacharacter.

Code:

]$ cat huh 

nelson

nelso

nels

Code:

grep '\bnels\b' huh

nels

Cheers,
Tink
