I have worked on some simple Scripts that I use and like:
Resize Images – Resize all .jpg images in a folder and name the new smaller file small-(file).jpg This uses Image Magic
Remove Space – Simple Bash Script to remove all spaces and replace them with a dash (-) in all files in a folder
PDF to JPG – Convert all .pdf files in a folder to .jpg files using Image Magic
Get IP – Simple Batch Script to find the Public IP and display it.
