Batch Rename Files on Linux（批量重命名linux）

Linux is well known for its powerful and efficient batch rename capabilities. For example, if you want to rename all your photos as “photo-year-day_time.jpg”, you could easily do it with just a few commands.

Renaming files in Linux can be done in two ways: by using the command line (CLI) or a GUI. For example, to rename multiple files in CLI, you can use the “mv” command.

The “mv” command allows you to move one or more files from one location to another, or to rename a single file. To rename multiple files at once, you will need to use the wildcard character (*) to match multiple instances of the same filename.

Let us look at an example. Suppose we have multiple files named “file1.jpg”, “file2.jpg”, “file3.jpg”, etc. To rename all these files to “photo-year-day_time.jpg”, we will use the following command:

mv *jpg photo-year-day_time.jpg

This command will move all the files with a .jpg extension and rename them to “photo-year-day_time.jpg”.

Apart from the command line, GUI tools such as Nautilus and Thunar can also be used to batch rename files. To use Nautilus, simply navigate to the directory where the files are located and select the files you want to rename. Once you have selected all the required files, right-click on it and go to ‘Rename’. In this dialog box, you will be able to enter the new filename, select the type of batch rename operation you want to perform, and then click on ‘Rename’.

Another useful technique is to use a bash script. This allows you to create a script that can loop through all the files in a directory and rename them with the same name and extension. Here’s an example of a bash script to batch rename files:

#!/bin/bash 
  
for filename in *.*; do 
    mv “$filename” “photo-year-day_time.jpg”
done
``` 

This script will loop through all files in the current directory and rename them to photo-year-day_time.jpg.

Finally, several GUI tools are available for Linux, such as ‘Rename Master’ and ‘Bulk Rename’, which can be used to batch rename files. These tools provide a range of options, such as searching and replacing text, adding prefixes and suffixes, and changing the file extension. 

Batch renaming files on Linux is an extremely useful skill to have, as it can be used to easily rename multiple files with the same extension. In this article, we discussed how to batch rename files using the command line, Nautilus, and bash scripts. We also discussed a few GUI tools that can be used to batch rename files.
