Doing this manually for a large number of files isn't just time-consuming, but it can also lead to errors. Luckily, Linux provides us with handy tools to accomplish this task efficiently.

The Solution: Using the rename Command

What is the rename Command?

The rename command in Linux is a powerful utility that allows you to change file names using regular expressions. This enables you to specify patterns and replacements, making it much easier to rename multiple files at once.

The Command Breakdown

To rename files as described above, you can use the following command:

How It Works:

rename: Invokes the rename command.

's/_new//': This is a Perl regular expression, which means:

s/pattern/replacement/: This syntax tells rename to substitute 'pattern' with 'replacement'.

Here, it specifically looks for _new and replaces it with an empty string (i.e., removes it).

*_new.txt: This part selects all files that end with _new.txt. The asterisk (*) serves as a wildcard to match any preceding characters.

Step-By-Step Guide

Open the Terminal on your Ubuntu system.

Navigate to the directory containing the files you wish to rename. You can change directories using cd path/to/directory.

Run the command: Type in the precise command shared above and hit enter.

Verify the filenames have changed as expected. You can use ls to list the files in the directory to confirm the new names.

Advantages of Using rename

Efficiency: You can rename thousands or millions of files in a single command.

Speed: Executes quickly, saving you valuable time.

Simplicity: No need to write complicated scripts or loops.

Conclusion

Renaming multiple files in Linux doesn't have to be a tedious task anymore. With the rename command, you can simplify your workflow and manage your files with ease. The command we explored is effective for specific renaming patterns, and you can adapt it for various other types of changes as well.

Whether you are a casual user or a system administrator, mastering file management commands can significantly boost your productivity. Embrace the power of the rename command today and transform how you interact with your files!
