About the Course

UNIX Basics and Shell Scripting


UNIX is a multitasking, multi-user computer operating system that exists in many variants. UNIX is the oldest and most secure operating system architecture present today. Linux/Unix is still used today in a lot of servers. Almost 80% of the websites are running on UNIX servers.


Shell Scripting Introduction


Unix uses shells to accept commands given by the user, there are quite a few different shells available. The most commonly used shells are SH(Bourne SHell) CSH(C SHell) and KSH(Korn SHell), most of the other shells you encounter will be variants of these shells and will share the same syntax, KSH is based on SH and so is BASH(Bourne again shell). TCSH(Extended C SHell) is based on CSH.


The various shells all have built in functions which allow for the creation of shell scripts, that is, the stringing together of shell commands and constructs to automate what can be automated in order to make life easier for the user.
