Use the -c option with su, and call a new script to run as that user.
In case you aren't sure about that option, use it as follows: su user2 -c user2script.sh If you only want to run one command as user2, you could simply insert that command after the -c instead. su user2 -c whoami A side note, if the command is more than one word, you must enclose it in quotes. For example: su -c 'find / -name \*.c -print' user2 (obviously the order of -c command and the user is interchangeable). Jacques B.
