[opensuse] su no longer working
I've been doing some rearrangement on my system (SUSE 11.1) using the command su in order to run root required commands. All of a sudden the su command no longer works. The following is an example of what has happened: eck@linux-dria:~>su Password: linux-dria:/home/eck # df linux-dria:/home/eck # cd / linux-dria:/ #ls -lag linux-dria:/ # Notice that nothing happens. What might of happened to cause this? I can login to one of the virtual terminals as root and there is no problem.

eck@linux-dria:~>su
The su command uses the profile of the current user. Try using "su -" minus the " marks ie: eck@Linux-dria:-> su - Password: -- Michael S. Dunsavage -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Of you done anything special to your system when you "rearranged" it? Could you run strace -f df when you of su:d to root, and post the output? Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That is true, but that shouldn't have affected the output of the commands Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Maybe... I'm wondering if there's a shell "feature" that lets you redirect output to something other than the screen. Like to a nul device or something. Try starting su under a different shell from what you usually use and see if it does the same thing. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Delete files under /home/eck/bin Don't know exactly how command files like df wound up under /home/eck/bin but removing all the files appears to have solved the problem. I wonder what else is lurking on my system because of the "rearrangement". Anyway thank Andrens for you suggestion.
