How to Rename a Directory in Linux

Introduction

Renaming a directory is one of the most basic tasks you will perform on any operating system. The Linux terminal offers several different ways to rename directories using commands and scripts.

In this tutorial, we will go over the different methods you can use to rename a directory in Linux through the terminal window.

Prerequisites

• A system running a Linux distribution
• An account with sudo privileges
• Access to the terminal window/command line
• Access to a text editor, such as Vim or Nano

Renaming Directories With the mv Command

The primary function of the mv command in Linux is moving files and directories from one place to another. It uses the following command syntax:

mv [options] [source] [destination]

If the destination directory does not exist, the mv command renames the source directory instead. In this case, the syntax changes to:

mv [options] [current directory name] [new directory name]

As an example, let's say we have Directory1, Directory2, and Directory3 in our Home directory:

To rename Directory1 into Example_Directory with the mv command, use:

mv Directory1 Example_Directory

There is no output if the command is successful, so we need to use the ls command to verify the name change:

ls -l

Renaming Directories With the rename Command

The rename command in Linux is a dedicated command used to change the names of files and directories. Using this command makes it easier to rename multiple directories at the same time.

Renaming a Single Directory With the rename Command

The rename command uses the following syntax:

rename [options] 's/[expression]/[replacement]/' [file name]

The command renames the file by replacing the first occurrence of the expression with the replacement. For example, if we want to rename Directory1 to Example_Directory:

rename 's/Directory1/Example_Directory/' *

In this example, we can see that the rename command syntax consists of several sections:

• rename: Invokes the rename command.
• s: Short for substitute, indicates that we are replacing the expression with the replacement.
• /Directory1: Specifies the expression or the part of the old directory name that you want to replace.
• /Example_Directory/: Defines the replacement or the new directory name.
• *: Searches the Home directory for names matching the provided expression.

Verifying the Home directory content with the ls command shows that the directory now has a new name:

Renaming Multiple Directories With the rename Command

The rename command provides a way to rename multiple directories at the same time without using bash scripts. For instance, if we want to rename Directory1, Directory2, and Directory3 to Folder1, Folder2, and Folder3:

rename -v 's/Directory/Folder/' *

In the example above:

• -v: Invokes the verbose output, listing each step of the process.
• 's/Directory/Folder/': Replaces Directory in the names of the search results with Folder.
• *: Searches the Home directory for names matching the provided expression.

The rename command can also translate file names by using the y argument instead of the s argument. In this case, it translates one string of characters into another, character-for-character.

For instance:

rename 'y/abc/def/'

The command above translates every a character into d, every b into e, and every c into f.

In the example below, we translated blank spaces in directory names to underscores (_).

rename -v 'y/ /_/' *

Renaming Directories With the find Command

In case you are not sure where the directory you want to rename is located, using the find command with the mv command lets you search for it and rename it when it's found:

find . -depth -type d -name [current directory name] -execdir mv {} [new directory name] \;

In the example above, -execdir executes the mv command once the find command locates the directory.

For instance, the command below finds and renames Directory1 into Example_Directory:

find . -depth -type d -name Directory1 -execdir mv {} Example_Directory \;

Renaming Directories With Bash Scripts

Using bash scripts is another way of renaming multiple directories at the same time. Unlike the rename command, bash scripts allow you to save a template for future use.

Start by creating the script with a text editor, such as Nano:

sudo nano rename_directories.sh

The following example is a bash script that searches for directories and appends the current date to their name:

#!/bin/bash

#Searches for directories and renames them according to the specified pattern

for d in *
do
    if [ -d "$d" ]
    then
      mv -- "$d" "{d}_$(date +%Y%m%d)"
    fi
done

In the example above:

• The first line instructs the script to go through all files and directories in the current location.
• Lines 2 and 3 check for directories.
• Lines 4 and 5 append the current date to the name of any directory found.

Press Ctrl+X, type Y, and press Enter to close and save the script.

As an example, let's use the script above to change the names of Directory1, Directory2, and Directory3, located in the Example directory.

Start by moving in to the Example directory:

cd Example

Next, execute the script by using the sh command:

sh rename_directory.sh

Using the ls command allows us to verify the name change:

ls -l
