Hi all:
Can I set SUID to a shell script that looks like the following: --------------------- #!/bin/bash
#Name: add4all.sh #Usage: add4all.sh username password
/usr/sbin/useradd $1 /bin/echo "$2" | /usr/bin/passwd --stdin $1 ------------------------
so that any user can use it?
Well, it's not really important but i'd like to know if it can be done.
Other than your script having errors (there is no --stdin option AFAIK), you can set the SUID bit on any executable, including a shell script and it will run as root, allowing anyone who can execute the script to use it.
Of course, it is very dangerous to do this, because once you get the script working above, anyone could change the root password and own your machine. Generally, SUID programs/scripts are a bad idea. Look at the sudo command if you want to share some admin responsibilities without sharing root.
