Why am I unable to execute command as another user in CentOs?

  • 772

On a remote server, it used to be the case that it was possible to execute a command as another user using the sudo -u command but lately, I have been unable to accomplish this. When I do I receive the following error:

sudo -u lool ./autogen.sh 
/var/tmp/scltjLjKc: line 8: -u: command not found

so I'm having to resort sudo-ing to root then su into the user before being able to execute the command. What could be the possible cause of this?

centos bash sudo centos6.5

  1. Since this never got an answer, the comment by Zoredache is correct. Installing one of the devtoolset-* software collections is responsible for this problem. I can't imagine who thought hijacking sudo was a reasonable or responsible thing to do.

    The quickest way to resolve it, without messing with your path and possibly breaking the development tools you've just installed is to do this:

    # alter the file, so that it won't get overwritten by updates
echo '### garbage ####' >> /opt/rh/devtoolset-2/root/usr/bin/sudo
# make it non-executable so your system won't try to run it
chmod -x /opt/rh/devtoolset-2/root/usr/bin/sudo

    Of course, replace devtoolset-2 with whatever version you're using.
