In this issue, I will bring you some information about how to rename files using rename command in Linux. The article is rich in content and analyzes and narrates from a professional perspective. After reading this article, I hope you can gain something.

The rename command is used to rename multiple files. This command is more advanced than mv because it requires some basic knowledge of regular expressions. It comes in two versions: the C version and the perl version; the syntax varies from version to version.

Here's how the perl version of rename is used. If this version of the rename command is not installed, it can be easily installed using the distribution's package manager.

Install rename command on Ubuntu and Debian

sudo apt install rename

Install rename command on CentOS and Fedora

sudo yum install prename

Install rename command on Arch Linux

yay perl-rename ## or yaourt -S perl-rename

Basic syntax for rename command:

rename [OPTIONS] perlexpr files

The rename command renames all files according to the specified plexpr regular expression.

Examples:

Change all files with.html extension to.php

rename 's/.html/.php/' *.html

You can use the-n parameter to print the names of files that need to be renamed without having to rename them.

rename -n 's/.html/.php/' *.html

The output looks like this:

rename(file-90.html, file-90.php)rename(file-91.html, file-91.php)rename(file-92.html, file-92.php)rename(file-93.html, file-93.php)rename(file-94.html, file-94.php)

By default, the rename command does not overwrite existing files; however, passing the-f argument allows existing files to be overwritten.

rename -f 's/.html/.php/' *.html

Common examples of using the rename command

Replace spaces in file names with underscores

rename 'y/ /_/' *

Convert file names to lowercase

rename 'y/A-Z/a-z/' *

Convert file names to uppercase

rename 'y/a-z/A-Z/' * The above is a small series for everyone to share how to rename files using the rename command in Linux?
