What type of shell do you use?
Add set -x at the start of the script and set +x at the end of it.

Post the output of this when executing it, using code tags.

I am using bash sh shell.

after giving the set -x command the output is something like this:

Code:
+ val=0
+ + su - test -c umask
+ grep -v logout
+ tail -2
02
02 -eq 02 ]
emh.sh[4]: ^M^[[3g^M ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H ^[H^M02: Syntax error

Looks to me as if you have some ^M in there plus some others which cause the trouble.
Do you write this script on a Windows box?
Else your code syntax looks fine.
