if statement

Comment:

I have a file that consists of a blank line, then either Y or N and then another blank line. I want to take this into an if statement saying if the file contains a Y then do this else do that. I've tried a few ways but i think i am getting my code a bit wrong. what's the best way to do this?

Reply:

if [ "$( sed -e '/^$/d' file)" = "Y" ]; then echo "do this" else echo "do that" fi;

Or just if grep Y filename 2>&1 >/dev/null then echo "Do this" else echo "Do that" fi Some grep implementations have a -s (silent) option or similar, which lets you do without the "2>&1 >/dev/null".
