# Lock Folders

Use this script to lock the following folders: Documents, Downloads, Music, Pictures, Videos, snap, Public, Templates for both Standard and Sudo Users on Linux machines.

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-D32HZ1U2.png)

```bash
#!/bin/bash

# Define directories to lock
DIRECTORIES=("Documents" "Downloads" "Music" "Pictures" "Videos" "snap" "Public" "Templates")

# Function to lock down and make folders immutable for a given user
lock_and_immute_folders() {
    local user="$1"
    local home_dir="/home/$user"
    
    echo "Processing user: $user"

    # Check if home directory exists
    if [ ! -d "$home_dir" ]; then
        echo "Error: Home directory $home_dir not found for user $user"
        return
    fi
    
    # Loop through each directory and lock it
    for DIR in "${DIRECTORIES[@]}"; do
        local folder="$home_dir/$DIR"
        if [ -d "$folder" ]; then

            if [ $? -eq 0 ]; then
                echo "Locked $folder for user $user"
