copied!<p>The ps output gives you a clue. The thing you're running is bash with your script as an argument. Since bash isn't suid, it can't elevate permissions.</p> <p>Linux - and most unixes - don't allow suid shell scripts either way. It's implemented as part of the exec() system call that they ignore suid/sgid on anything being interpreted through the #! mechanism (see <code>man execve</code>). To work around this, you'll most likely want to use sudo and potentially call it from within your shell script (which is somewhat safer anyway).</p> <p>To run part of the script using sudo, you would use the -u or -g options to sudo to launch your script. So, you'd make a rule in /etc/sudoers (which is beyond the scope of this answer) allowing you to run the script. Say your script is /tmp/script, and you're abc. to run the command as the user "sauer" without being prompted for your password, you'd add this to /etc/sudoers:</p> <pre><code>abc ALL = (sauer) NOPASSWD: /tmp/script </code></pre> <p>and run this command</p> <pre><code>sudo -u sauer /tmp/script </code></pre> <p>To run it as a member of the admin group, you'd add this line:</p> <pre><code>abc ALL = (%admin) NOPASSWD: /tmp/script </code></pre> <p>and run this command</p> <pre><code>sudo -g admin /tmp/script </code></pre> <p>Read the sudoers man page and surf around Google to find more documentation on sudo. You combine users and groups with commas in that parenthetical expression (ie, <code>(sauer,root,%admin)</code>)</p>
