Really? Hmm, well, perhaps you could do it a similar way:

db_tmp=`db2 "get instance"`
db_name=`echo $db_tmp | awk -F": " '{print $2}'`

Then, either do this:
cd /top/$db_name/apps/log/

or this, if the above doesn't work:

case $db_name in
db2q) cd /top/db2q/apps/log/ ;;
db2u) cd /top/db2u/apps/log/ ;;
*) echo "Eek." ;;
esac

I'm not saying that you're doing it wrong - I guess I just feel uneasy with grepping a string out of a file... I usually try to touch the disk as little as possible in a small script.

Hmm, what do you think about this:

db2 "get instance" | grep "db2q" >/dev/null 2>&1
case $? in
0) cd /top/db2q/apps/log ;;
1) cd /top/db2u/apps/log ;;
*) echo "This should never happen." ;;
esac

That way is very similar to how your are doing it now, and I find case statements a little cleaner than if statements, but that's just my opinion.

Well, I hope this is helping at least a little...

It just goes to show how many ways there are to accomplish a task in Unix!
