.SH NAME
|
||
|
|
\fBsu\fR - Run a command with a substitute user and group ID
|
||
|
|
.SH SYNOPSIS

|
\fBsu\fR [\fB-lp\fR] [\fIuser\fR]

|
.SH DESCRIPTION
|
||
|
|
\fBsu\fR allows to run commands with a substitute user and group ID.
|
||
|
|
When called without arguments, su defaults to running an interactive shell
|
||
|
|
as root. For backward compatibility su defaults to not change the current
|
||
|
|
directory and to only set the environment variables \fBHOME\fR and \fBSHELL\fR
|
||
|
|
(plus \fBUSER\fR and \fBLOGNAME\fR if target \fIuser\fR is not root).
|
||
|
|
