What is a Folder in Linux?

In Linux, a folder is referred to as a directory. Just like in other operating systems, directories are used to store and organize files and other directories. All directories in Linux are part of a hierarchical file structure, starting from the root directory /.

Why Rename a Folder in Linux?

There are many reasons to rename a folder:

• To reflect updated content or purpose

• To fix typos in folder names

• To follow a consistent naming convention

• To organize files for a project or backup

Regardless of the reason, renaming is a common and useful operation that helps keep your Linux system organized.

Method 1: Using the mv Command (Command Line Method)

The most common and recommended way to rename a folder in Linux is by using the mv (move) command. This method works in almost every Linux distribution and is simple once you get used to the terminal.

 Syntax:

mv [old_folder_name] [new_folder_name]

 Example:

mv my_folder my_renamed_folder

In this command:

• my_folder is the current name of the directory

• my_renamed_folder is the new name you want to give it

After executing this command, the folder is renamed immediately.

 Important Tips:

• Make sure you're in the correct directory, or use full paths.

• Use the ls command to list directory contents before renaming.

Method 2: Renaming with Absolute Paths

You can also rename folders located in different directories by providing absolute or relative paths.

 Example:

mv /home/user/docs/old_folder /home/user/docs/new_folder

This command will rename the folder regardless of your current working directory.

---

Method 3: Rename with sudo (if permission denied)

Sometimes, renaming a folder requires superuser permissions, especially in system directories.

Example:

sudo mv /var/www/html/site /var/www/html/website

The sudo command runs the operation with administrative privileges. You’ll need to enter your password.

---

Method 4: Using a Graphical File Manager

If you're using a Linux desktop environment like GNOME, KDE, or XFCE, you can rename folders just like in Windows:

1. Open your file manager (e.g., Nautilus or Dolphin)

2. Right-click on the folder you want to rename

3. Select “Rename.”

4. Type the new name and press Enter

This is the easiest method for users who are not comfortable with the terminal yet.

---

Method 5: Rename Multiple Folders with a Script

If you want to rename several folders at once (e.g., remove spaces or change case), you can use a bash script.

 Example: Remove spaces from folder names

for dir in *; do
  mv "$dir" "${dir// /_}"
done

This script loops through all folders in the current directory and replaces spaces with underscores.

Common Errors and How to Fix Them

🔴 “No such file or directory”

• Check your spelling and use ls to verify the folder exists.

🔴 “Permission denied”

• Use sudo if you don’t have write permissions.

🔴 “Is a directory”

• You’re trying to move a file with the same name as a directory. Make sure paths and names are correct.

---

Extra Tips for Beginners

• Use pwd to check your current location in the terminal.

• Use cd to navigate into or out of directories.

• Always double-check before using mv—it can overwrite files or folders if not used correctly.

• Use the -i flag to prompt confirmation before overwriting:

  mv -i old_folder new_folder

Bonus: Rename a Folder Using rename Command (Optional Tool)

Some Linux systems have a rename command for batch renaming. However, it is more commonly used for files. It's not ideal for single folder renaming, but useful for advanced users.
