ssu command

The ssu command allows an unprivileged user to become root on the local machine without changing his SFS credentials. ssu invokes the command su to become root. Thus, the access and password checks needed to become root are identical to those of the local operating system's su command. ssu also runs /usr/local/lib/sfs-0.6/newaid to alter the group list so that SFS can recognize the root shell as belonging to the original user.

The usage is as follows:

ssu [-f | -m | -l | -c command]
-f
-m
These options are passed through to the su command.
-l
This option causes the newly spawned root shell to behave like a login shell.
-c command
Tells ssu to tell su to run command rather than running a shell.

Note, ssu does not work on some versions of Linux because of a bug in Linux. To see if this bug is present, run the command su root -c ps. If this command stops with a signal, your su command is broken and you cannot use ssu.
