• What is Shell Scripting
• A shell script is a text file that contains a
  sequence of commands for a UNIX-based operating
  system. It's called a shell script because it
  combines into a "script" in a single file a
  sequence of commands that would otherwise have to
  be presented to the system from a keyboard one at
  a time.

• Being a Linux user means you play around with
  the command-line. Like it or not, there are just
  some things that are done much more easily via
  this interface than by pointing and clicking. The
  more you use and learn the command-line, the more
  you see its potential. Well, the command-line
  itself is a program the shell. Most Linux
  distros today use Bash, and this is what youre
  really entering commands into.

• 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.
