su
su(1) General Commands Manual su(1)Name
su - substitute a user ID
Syntax
su [username]
su - [username]
su -f [username]
Description
The command requests the password of the specified username. If the correct password is given, changes to that username without changing
the current directory. The user environment is unchanged except for HOME and SHELL which are taken from the password file entry for user-
name. The shell that is run is also taken from the password file entry for username. The new user ID stays in force until the shell
exits.
If no username is specified, `root' is assumed. To remind the superuser of his responsibilities, the shell substitutes `#' for its usual
prompt.
Options-f Prevents from executing the .cshrc file, making start up faster.
- Simulates a full login.
Diagnostics

No directory
