That looks like it should work, though like I said, the grep/awk solution would be more efficient. Maybe you should put double-quotes around the $line, as in:

Code:

case "$line" in

In ksh and bash, you can also parse out the first word from the rest:

Code:

case "${line%% *}" in
   first|second|third) echo "$line";;
esac
