Basic Shell Scripting
This is a basic shell scripting tutorial i got off the Net. Credit goes to the writer. By the way, the site i ripped this off was at http://more-shell.blogspot.com/2007/03/easy-shell-scripting.html Easy Shell Scripting By Blessen Cherian Shell scripting can be defined as a group of commands executed in sequence. Let's start by describing the steps needed to write and execute a shell script: Step 1: Open the file using an editor (e.g., "vi" or "pico".) vi Firstshellscript.sh Step 2: All shell scripts should begin with "#!/bin/bash" or whatever other shell you prefer. This line is called the shebang, and although it looks like a comment, it's not: it notifies the shell of the interpreter to be used for the script. The provided path must be an absolute one (you can't just use "bash", for example), and the shebang must be located on the first line of the script without any preceding space. Step 3: Write the code that you want to develop.
