Some useful shell Scripts by me
unrar
The unrar tool by Alexander Roshal doesn't support extracting multiple .rar files (ie. unrar x file1.rar file2.rar or unrar x file*.rar)
This tiny script fixes that.
Usage: unrar file*.rar
This will unrar all files like file1.rar, file2.rar etc.
qltoicon
This requires fileicon from https://github.com/mklement0/fileicon in your $PATH
This script applies the icon preview from QuickLook as a icon. This is good for comic book files which take a long time to generate icon previews. With this you apply it as a icon one time and always get the nice icon without waiting.
