>From "man grep":
-w, --word-regexp
Select only those lines containing matches that form whole
words. The test is that the matching substring must either be
at the beginning of the line, or preceded by a non-word con-
stituent character. Similarly, it must be either at the end of
the line or followed by a non-word constituent character. Word-
constituent characters are letters, digits, and the underscore.
For example:
[EMAIL PROTECTED] root]# grep -w auto /var/log/messages | tail -n 2 -
[EMAIL PROTECTED] root]# grep -w automount /var/log/messages | tail -n 2 -
Mar 17 07:15:57 houuc8 automount[2045]: expired /home/tidwell
Mar 17 09:18:07 houuc8 automount[2685]: attempting to mount entry /software/utils

That will work if the word is on a line by itself. If there may be other
words on the line, try this:
grep '\Wsomething\W'
That will match the target string only if it surrounded by non-word
characters (whitespace, puncutation, end-of-line).
