set UID on linux
Hi,
I just want to know if it's possible to set the UID bit for a script, so that it executes not as a owner of process, but owner of the script.

i.e
script tesh.sh owned by 'user1', 'file1' owned by user1 has 700 permisssions
`who am i`
rm -v /tmp/file1

user 2 need to execute test.sh,

so I would issue
chmod u+s test.sh first to set the UID

then ,
I would execute the script as user2, by doing so , i would expect the 'file1' to be removed, as I would expect the script is being executed as user1 and not user2. However it doesn't seem to happen ?

Any reasons why ??

Thanks

A lot of systems don't support the setuid bit on scripts. If you write a C program and make that setuid, it should work.
