I think sudo's '-S' option may come to the rescue. I tried to replicate
the functionality of this part of the instructions: "sudo -u
squeezeboxserver sudo /sbin/shutdown -k -h now" with this: "sudo
testsudo.sh"
Code:
--------------------
#!/bin/bash
USER="squeezeboxserver"
HOST=`hostname -s`
if [ "$EUID" -ne 0 ]; then
echo "Please run this command as 'sudo $0'. Exit"
exit 0
fi
/usr/bin/wall <<END;
** Testing ${USER}'s ability to run privileged commands on $HOST **
You may now see a message announcing immediate shutdown.
This is only a test. Host $HOST WILL NOT really shutdown.
END
sleep 5;
# reset timestamp
sudo -k;
# send a wrong passwd from stdin if asked for it => OK = 0
echo "" | sudo -S -u $USER sudo -S /sbin/shutdown -k now > /dev/null 2>&1 &&
OK=1 || OK=0;
if [ "$OK" -eq 1 ]; then
echo -e "\nSuccess!\n";
else
echo -e "\nThere was a boo-boo.\n";
fi
--------------------
Seems to work for me (debian, OS X) Is it useful to you ?
NB: I switched to using bash only because I had trouble with "echo -e"
on OSX using sh. Remove the -e and sh will do nicely.
