# Lock active user session on the Linux device

The following script locks the currently active user session on a Linux system. This might be used to quickly secure a session, such as when stepping away from the computer.

> [!NOTE]
> Note:
> 
> Repeat execution of scripts is not supported, hence please delete and re-upload the script and Publish each time you would want to lock device.

1. Copy and save the contents below to a **UTF-8** editor like **notepad++** OR **Sublime Text** in Windows or **gedit** in Ubuntu.
  1. If you are using **notepad++** then use the bottom right panel to change the type to **Unix (LF)**. ![](https://cdn.document360.io/175c0eac-012f-4410-bdc5-ac60794f82d8/Images/Documentation/image-FSW1EZBX.png)

```bash
#!/bin/bash

# Find the active session
session_id=$(loginctl list-sessions --no-legend | awk '{print $1}')
if [ -n "$session_id" ]; then
    # Lock the active session
    loginctl lock-session "$session_id"
    echo "Locked session $session_id"
else
    echo "No active session found."
fi
```
3. Follow [our guide](/docs/deploy-linux-shell-scripts-using-scalefusion#step-1-upload-and-deploy-the-script) to upload & publish the script using Scalefusion Dashboard.
