The setuid is not honored for shell scripts, try it and you will see.

Hi Todd,
why don't you just use setuid ?

You just change the script owner or group to root.
And put the s bit with the chmod command.
That's all.

Hi All,
I have a bash script that need to be run as root.
In the script, I check to see if it is running as
root and flag the user to run appropriately.
Is there a way to use "su" to prompt for the password
and continue the script if successful? (I would test for
$? after the prompt.)
Currently "su" will just open a new shell as root.
I can run a command inside "su", but what about the
other 200 lines of code? :'(
An interesting problem :-)
Something like this seems to work but I haven't thought through
the consequences of it, so be aware:
-----cut here-----
#!/bin/sh
this_script=$(basename $0)
if [ $(id -u) -ne 0 ]
then
echo "Enter root's password"
su -c ./$this_script
exit
fi
echo "Hello world"
echo "Running as $(id -u)"
-----cut here-----
You probably need to do something with $PATH to obviate the
need for the "./" on the su line.
Hi Mark,
I get it. Fascinating!
If not root, call myself a second time with "su"
Thank you!
