. Once installed, you can start using the command to rename files. For instance, if you want to replace spaces in filenames with underscores, you can run the following command:

. This command uses the regular expression pattern

to substitute all spaces with underscores in the filenames of all files in the current directory.

Example: Renaming Files with the rename Command

Let’s say you have a directory containing multiple image files with names like

,

,

, and so on. Now, you want to prepend the word “new_” to the filenames of all these images. You can achieve this by running the following command:

1	rename 's/^/new_/' *.jpg

This command uses the regular expression pattern

to add the prefix “new_” to the beginning of each filename that ends with “.jpg”. As a result, the filenames will be renamed to

,

,

, and so on.

In conclusion, the rename command is a valuable tool for bulk file renaming in Linux. With its flexibility and support for regular expressions, it allows you to efficiently rename multiple files at once. By mastering this command, you can streamline your file organization and management tasks.

Option	Description
-v	Enables verbose mode, displaying details of each file that is renamed.
-n	Performs a dry run, showing the files that would be renamed without making any changes.
-o	Prevents overwriting files with the same name.
-f	Forces the overwrite of files with the same name.

Using the mmv Utility for Batch File Renaming in Linux

Another handy tool for bulk file renaming in Linux is the mmv utility, which provides a simple and efficient way to rename files based on wildcard patterns. Unlike the rename command, which uses regular expressions, mmv uses standard wildcards to match and modify filenames.

To install the mmv utility, you can use the command

. Once installed, you can start renaming files using mmv.

Let’s say you have a folder containing multiple image files with the extension “.jpeg” and you want to change it to “.jpg”. With mmv, you can achieve this with a single command:

1
mmv "*.jpeg" "#1.jpg"

The wildcard expression “*.jpeg” matches all files with the “.jpeg” extension, and the “#1” in the destination pattern represents the original filename without the extension. The command will rename all the files accordingly.

Furthermore, mmv allows you to perform more complex renaming tasks. For instance, if you have a folder with filenames in the format “file_name_DATE.extension” and you want to switch the positions of the filename and date, you can use the following command:

1
mmv "*_*_*" "#3_#2_#1"

This command will extract the different components of the original filename using the “_” delimiter and reorder them in the desired format.

Overall, the mmv utility is a versatile tool for batch file renaming in Linux. With its wildcard-based approach and straightforward syntax, it offers an efficient solution for renaming multiple files at once.
