Linux Command Line Tutorial For Beginners 20 - Introduction to Bash Scripting

INTRODUCTION TO SHELL PROGRAMMING
. Shell programming is one of the most powerful features on any UNIX system
. If you cannot find an existing utility to accomplish a task, you can build one using a shell script

SHELL PROGRAM STRUCTURE

A shell program contains high-level programming language features:
. Variables for storing data
. Decision-making control (e.g. if and case statements)
. Looping abilities (e.g. for and while loops)
. Function calls for modularity
. A shell program can also contain:
. UNIX commands
. Pattern editing utilities (e.g. grep, sed, awk)

Very nice video. But i don't understand what is the point of user permission if the user can change the permission?

Hey! No fair bashing a shell. Especially me, and I'm not bashful. I sell C shells like she sells, only dyslexic. But if you're Bourne again, then go for what you believe in. But what's with Nano? It's just an enhanced version of Pico. And it ain't 1000 times as good, neither. You know, vim is so much better, and not really that much harder to learn or use. Of course, you can always fire up a MS-DOS 3.3 VM and use Edlin... if it's more your speed. ..
