su
Synopsis
su [option
] [user
] [shell_args
]
Creates a shell with the effective user ID user
. If no user
is specified, creates a shell for a privileged user (that is, becomes a superuser). Enter EOF
to terminate. You can run the shell with particular options by passing them as shell_args
(e.g., if the shell runs sh, you can specify -c
command
to execute command
via sh or -r to create a restricted shell).
Options
-
-c
command
Execute
command
in the new shell and then exit immediately. Ifcommand
is more than one word, it should be enclosed in quotes—for example:$
su -c 'find / -name \*.c -print' nobody
- -f
If the shell is csh or tcsh, this suppresses the reading of the .cshrc file.
- -l
Go through the entire login sequence (i.e., change to user’s environment).
- -m
Don’t reset environment variables.
