Escalating Linux permissions to root

Caution

A user with SLXVM Linux-shell root permissions can—unintentionally or maliciously—execute commands that can render the SLX inoperable.

From the SLX-OS CLI prompt, enter start-shell to access the SLXVM Linux shell.
```
device# start-shell
Entering Linux shell for the user: admUser
[admUser@SLX]#
```
You can now execute commands that do not require root permissions.
To escalate your permissions, enter the Linux su root command.
```
[admUser@SLX]# su root
Password: 
```

Enter the root password.

After successful login, the following warning is displayed:

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.
[root@SLX]#

Enter Linux commands and run scripts as needed.
You can also run SLX-OS commands from the Linux shell.
To exit root level and return to the default SLXVM Linux shell, enter exit.
```
[root@SLX]#  exit
exit
[admUser@SLX]# 
```
To exit the default SLXVM Linux shell and return to the SLX-OS CLI, enter exit.
```
[admUser@SLX]#  exit
exit
