SUID works for shell scripts??

SUID works for shell scripts (bash)??

I'm user user1 need to execute a shell script (script.sh) which is owned by user2.
Code:
-rwsrwxrwx 1 user2 aduser 3518 Aug 21 05:33 script.sh

Only user2 has write privileges to write/copy a file in directory /dir1/subdir. Hence SUID bit permissions are set to that script.sh. But still not able to run the script from user1 account. It says permissions denied to /dir1/subdir.

But the same script (script.sh) runs successfully from user2 account and able to copy/write a file in /dir1/subdir.

I don't have any clue.. Please help me..

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
