Writing a script to do bulk file renaming might seem like gibberish to the common user. But for users that need a tool to accomplish this task in seconds GPRename does the trick.
You can even adjust files to uppercase and lowercase, or just the first letter if you want. GPRename can even append numbers to multiple files or directories. Like most Linux tools GPRename comes in many languages and is available for free.
GPRename offers a simple interface and easy to understand menus. You can browse through your files and directories from the panel on the right hand side of the main window.
If you want to try GPrename use these commands in your terminal.
$ sudo apt-get install gprename
These are actions available in the tabs at the bottom of the GPRename window.
Case Change – You can change your filename text to all uppercase, or all lowercase. The first letter of the filename can also be changed, or the first letter after specified characters.
Insert And Delete – You can also insert characters or text into your filenames and a specified position. Or you can delete characters between specified positions.
Replace And Remove – You can replace specified text or characters with alternative patterns that you specify.
Numerical – From this tab you can insert numbers at any position in your filenames. You can even choose to insert numbers before or after other specified numbers.
