# The `su` command
|
|
|
|
In linux, `su` allows you to run commands with a substitute user and group ID.
|
|
|
|
When called without arguments, `su` defaults to running an interactive shell as root.
|
|
|
|
## Example :
|
|
|
|
```bash
|
|
$ su
|
|
```
|
|
|
|
In case that you wanted to switch to a user called `devdojo`, you could do that by running the following command:
|
|
|
|
```
|
|
$ su devdojo
|
|
```
|
|
|
|
## The syntax of the `su` command is :
|
|
|
|
```bash
|
|
$ su [options] [-] [<user>[<argument>...]]
|
|
|
|
```
|
|
|
|
## Options :
|
|
|
|
```bash
|
|
-m, -p --> do not reset environment variables
|
|
-w --> do not reset specified variables
|
|
-g --> specify the primary group
|
|
-G --> specify a supplemental group
|
|
-l --> make the shell a login shell
|
|
-f --> pass -f to the shell (for csh or tcsh)
|
|
-s --> run <shell> if /etc/shell allows it
|
|
-p --> create a new pseudo terminal
|
|
-h --> display this help
|
|
-v --> display version
|
|
```
