If you would prefer to remove directories using Linux commands, open your command line interface. In Ubuntu, press Ctrl-Alt-T to open the command line — this varies by distro.

How to delete a file using Linux's command-line interface The Linux command-line interface has an unearned reputation for being overly technical.

There are many ways to clean up or remove files, including using commands such as rm (remove), rmdir (remove directory), shred, and unlink.

From the command line, type "backup.bat" and the batch file will run your specified commands: first, copying all files from that directory, then renaming them to remove the extensions.
