Questions tagged [su]

GENERAL SU SUPPORT IS OFF-TOPIC. Support questions may be asked on https://superuser.com. su is a utility to run a shell or other command as another user (root by default).

su is a Unix/Linux utility that runs a shell or a specified command as another user. By default, the other user is root, and su, with , is one of the two common ways of obtaining administrator privileges. Calling su usually requires typing the target user's password.

su originally stood for “super user” (it was only for running a root shell), and became later known as “substitute user” (or “switch user” or a number of similar backronyms) when it started accepting the target user name as an argument.

For system administration questions, see the su tag on Super User (for non-professionals), Server Fault (for professionals), or Unix & Linux.
