mv Command in Linux {With Examples}

Introduction

The mv command is a UNIX utility for renaming and relocating files and directories in a filesystem. While desktop operating systems also offer a GUI method for file manipulation, there are cases in which using mv in a terminal can be a more efficient solution.

This article shows you how to use the mv command in Linux, provides a list of options, and offers illustrative examples.

Prerequisites

• Command-line access.
• An account with sudo privileges for moving root-owned files.

mv Command Syntax

The mv command works with files and directories, yielding different results depending on the used arguments. There are four basic ways to execute an mv command:

• Rename a file. Type the source filename and the destination filename:

mv [options] [source-file] [destination-file]

• Rename (or move) a directory. Type the source directory and the destination directory. If a destination directory exists, mv moves the source directory to the specified destination.

mv [options] [source-directory] [destination-directory]

• Move a file, preserving the filename. Type the filename followed by the destination directory.

mv [options] [file] [destination-directory]

• Move a file and change its name. Type the filename followed by the destination directory and a new filename.

mv [options] [file1] [directory/file2]

mv Command Options

According to the POSIX standard, the mv command has only two options: -f (force remove) and -i (interactive mode). However, depending on the OS and the version of the mv command, more useful options are available as arguments.

Below is a list of the most common mv options.

mv Command Examples

As seen above, the mv command is a simple but versatile file management utility. The sections below provide examples of the most common mv operations.

Rename File

Rename the file name1 to name2 with the following command:

mv name1 name2

The command produces no output, but the ls command shows the operation was successful.

View Command Output

Rename the file name1 to name2 and print the output:

mv -v name1 name2

The command produces an output containing the list of the performed actions.

Move Multiple Files

Move the files name1, name2, and name3 to dir2 in the home directory and show the verbose output:

mv -v name1 name2 name3 test-dir

The output shows that the files have been moved successfully.

Ask Before Overwriting

Rename name1 to name2, but show a prompt to overwrite if the file name2 already exists.

mv -v -i name1 name2

In the example below, the file name2 was already in the directory. The mv command prompted to overwrite the file and replaced its contents with the contents of name1.

Create File Backup

Move the file name1 to the directory test-dir. If the file of the same name exists at the destination, create a backup with the extension .bak:

mv -S .bak -b name1 test-dir/name1

After the command executes, the directory contains two files:

• name1 is the moved file.
• name1.bak is a backup of the file initially present in the directory.

Batch Rename Files

Combine mv with the Bash for loop to rename multiple files in one command. For example, to add the prefix test_ to all the files in a directory, type:

for file in *; do mv "$file" "test_$file"; done

Listing the directory contents shows that all the filenames start with test_:
