Why? Do you think it weird that most Windows user couldn't write a .bat script? I've worked support at a large university that used Unix as its main desktop OS for staff and students in most departments. I'd bet that most people there couldn't write bash script. 90+% of peoples interaction with the OS was click browser icon, click e-mail icon, click text editor icon and click icon/type in name at command prompt of whatever programs they needed to get work done. Writing bash scripts is simply not something that ever came up for the vast majority of users.
