The -w option on grep isn't going to work as it appears that the zone name contains 'non-word' characters (a dash). Since this seems a pretty specific application in terms of your input (it seems that the data you are searching for is always in column 2), then something as simple as this might work for you:

Code:
grep " $zonename " filename

This will match the name you are checking with something in the file only if the string in the file has a leading and trailing space.

If the columns are separated by either a space or tab, then something like this would work (assuming egrep is available):

Code:
egrep "[ \t]$zonename[ \t]" filename

Hope this helps
