is SUID disabled for shell

Hi,
I have two file in my directory. "catter" file contains "cat ./file". And "file" contails "Hi ashish". I have SUID bit set for catter file. But when a different user in my group runs file catter, shell displays "Permission denied" message.

I just want to know can use of suid bit be disable for shell/normal users?
or am I interpreting this in wrong way?

I am using HP-UX.

Quote:
$
$ ls -l
total 8
-rwsr-xr-x 1 ashishp smbnull 11 Mar 22 14:21 catter
-rw------- 1 ashishp smbnull 10 Mar 22 14:21 file
$
$ cat catter
cat ./file
$
$ cat file
Hi ashish
$
a different user in my group tries to run catter. He gets message "permission denied"

Quote:
$./catter
cat: Cannot open ./file: Permission denied

Any suggestion why this is happening.

Thanks in advance,
-Ashish

Do the users attempting to execute the script `catter' have read &
execute permissions for the directory containing the script?

In HP-UX, suid is inhibited for shell scripts.

The directory has permission 755
