Script Shell
Rename several files in a directory with different extensions by adding the same suffixes on each name.
edit.txt, map.jpg, music.mp3 ⇒ edit_X.txt, map_X.jpg, music_X.mp3
The example above is for informational purposes but the script may well do more interesting things depending on your needs. The action performed by the script is irreversible, be careful when using it.
Put the script in the folder where you are working and run it
