How to Rename a File in Linux With Simple Command Line Options

The quickest way to rename a file in Linux is with the mv (move) command. Simply type mv currentname newname in your terminal, but that’s not all. We can use different parameters to help us and to protect ourselves. For bulk renaming operations involving multiple files, the rename command offers powerful pattern matching capabilities.

In this guide, you’ll learn how to rename single files and directories, batch rename multiple files, use helpful command flags to prevent mistakes, and explore both command-line and GUI options for file renaming in Linux.

How to rename a file in Linux with the mv command

The mv (move) command is the standard tool for renaming files in Linux. While its name suggests moving files between locations, it’s also the primary method for renaming files when you keep them in the same directory.

Basic mv command syntax

Basic mv command syntax: mv [current-filename] [new-filename]

The mv command takes two arguments: the source file (current name) and the destination (new name). Here’s a practical example:

$ mv august.png september.png

This renames “august.png” to “september.png” in a single step. If you specify a different directory in the destination, the file will be both moved and renamed.

Important note about file extensions: The terminal environment typically doesn’t protect you from changing file extensions the way most graphical file managers do. The extension is part of the filename, a label for the user, and can be changed at any time.

Be careful when typing your new filename: changing .png to .jpg won’t convert the image format, it will just change the label. If a file opens in the wrong program after renaming, check that you typed the extension correctly.

Renaming files with the interactive flag

One risk with the mv command is accidentally overwriting an existing file. If your destination filename already exists, Linux will overwrite it without warning.

To prevent this, use the -i (interactive) flag:

$ mv -i august.png september.png

If september.png already exists, you’ll see a prompt asking whether to overwrite it. Type “y” to confirm or “n” to cancel.

Alternatively, use the -n (no-clobber) flag to prevent overwrites entirely without any prompt:

$ mv -n august.png september.png

With -n, if the destination file exists, the command simply does nothing.

Using verbose mode to track changes

When you want to see exactly what the mv command is doing, add the -v (verbose) flag:

$ mv -v august.png september.png

This outputs a confirmation of the operation, showing you the source and destination filenames.

You can combine flags for maximum safety:

$ mv -iv august.png september.png

This shows you what’s happening and prompts you before any overwrites.

How to rename a directory in Linux

Renaming a directory works exactly the same as renaming a file. In Linux, a directory is essentially treated as a special type of file, so the mv command handles both identically.

To rename a directory called “2026” to “2027”:

$ mv 2026 2027

That’s all there is to it. The same flags (-i, -n, -v) work for directories just as they do for files.

How to rename multiple files in Linux

The mv command works well for single files, but it has limitations when you need to rename many files at once. For bulk renaming with pattern matching, you’ll want to use the rename command.

Installing the rename command

The rename command may not be installed by default on your Linux distribution. Here’s how to install it:

• Ubuntu or Debian: $ sudo apt install rename
• Fedora or CentOS: $ sudo dnf install rename
• Arch Linux: $ sudo pacman -S perl-rename.

To check if rename is already installed, type which rename in your terminal. If it returns a path, you’re ready to go.

Using rename command with patterns

On many Linux systems, rename supports Perl regular expressions to transform filenames. 

Here are common examples:

Change all .txt files to .md:

$ rename 's/.txt/.md/' *.txt

Add a prefix to all files:

$ rename 's/^/backup_/' *.png

Replace spaces with underscores:

$ rename 's/ /_/g' *

The basic syntax is rename ‘s/pattern/replacement/’ files. The s/ indicates a substitution, followed by what to find, what to replace it with, and which files to process.

Use the -n flag to preview changes without actually renaming:

$ rename -n 's/.txt/.md/' *.txt

This shows you what would happen, letting you verify before committing.

Renaming and moving files simultaneously

Since mv handles both renaming and moving, you can do both in one command. To rename august.png to september.png and move it into the 2026 directory:

$ mv august.png 2026/september.png

The directory path and filename are simply combined in the destination argument.

Renaming files using a GUI file manager

If you prefer not to use the terminal, most Linux desktop environments include file managers with built-in rename functionality:

• GNOME Files (Nautilus): Right-click the file and select “Rename,” or select the file and press F2.
• Dolphin (KDE): Right-click and choose “Rename,” or press F2.
• Thunar (XFCE): Right-click for “Rename,” or use F2.

The process is similar to renaming files in Windows or macOS. Select your file, trigger the rename function, type the new name, and press Enter.

While GUI methods work well for occasional renames, the command line is usually faster for bulk operations or when working on remote servers without a graphical interface.
