Shell Script

• If you have ever opened a book on programming,
  you would immediately recognize this as the
  traditional "Hello World" program. Save your file
  with some descriptive name. How about my_script?
• The first line of the script is important. This
  is a special clue given to the shell indicating
  what program is used to interpret the script. In
  this case, it is /bin/bash. Other scripting
  languages such as perl, awk, tcl,
  Tk, and python can also use this mechanism.

Shell Script

• 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.
