How can I bulk rename files in Linux?

In Linux systems, you can use scripts or command line tools to batch rename files. Here are some commonly used methods:

1. Utilize the command line tool rename: The rename command can assist you in renaming multiple files in batches, and the syntax is as follows:
2. Change the file name from ‘original file name’ to ‘new file name’ for the file.
3. For example, replace “old” with “new” in all file names ending in .txt.
4. Change the name of all files with a “.txt” extension that contain the word “old” to now contain the word “new”.
5. You can use the mv command and wildcards to batch change file names, for example, renaming all files that start with “old” to start with “new”.
6. Rename all files starting with “old” by removing the “old” prefix and replacing it with “new”.
7. Script Usage: You can also write a simple script to bulk modify file names, for example:
8. #!/bin/bash
   for file in *.txt; do
   mv “$file” “${file/old/new}”
   done

No matter which method you choose, remember to backup important files before making any changes to prevent accidental errors.
