Change Owner of a script in unix

Question

I have a unix shell script file whose owner is "xyz" when run deletes some specific files.

I want to trigger this script to delete files in some other directory where the owner for the files to be deleted is different from the owner of the script. Is this possible? Is this possible to run this script as different user so that it can delete those new files?

EDIT : I use Autosys to periodically trigger this script.

Usually you use sudo for that:

sudo -u ANOTHER_USER /path/to/the/script.sh

However, your current account needs proper permissions to do so. You can configure those permissions using the file /etc/sudoers.

You'll find a ton of articles out there how to use sudo. This for example: http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:Ch09:_Linux_Users_and_Sudo

I dont have sudo permissions on this server. I use a autosys script which periodically triggers this script. – user2133404 May 20 '14 at 19:39

Then this is not possible. You are actually experiencing security restrictions. – hek2mgl May 20 '14 at 19:40

You can chmod the files that need to be deleted first if you have sufficient rights. Afterwards your script, no matter what user it executes, will succeed.

yes, but will it be able to delete files owned by a different user? – user2133404 May 21 '14 at 14:27
Wouldn't you be able to delete them if you could chmod them? – UpAndAdam May 21 '14 at 14:35
user2133404 : yes you can – Sono May 21 '14 at 15:37
UpAndAdam : you could do the chmod with a different user using another autosys job. – Sono May 21 '14 at 15:43
