You may not like it but this simple part 1 has taught some things already:

1. The first line contains a line that determines what shell is used.
2. Commands run on the command line are written the same way in their script.
3. Variables can be created easily and values in them can be reused all through their script.
4. That they can redirect any output into a file.

However, that said I would like to add (for clearification) the following things to this tutorial:

1. The line #!/bin/bash is often called the “shabang” (‘http://en.wikipedia.org/wiki/Shebang_(Unix)‘) and can be any interpreter or shell (/usr/bin/perl, /bin/ksh, etc…)
2. Redirection using ‘>’ or ‘>>’ will overwrite (>) or append (>>).
3. Creating a variable in bash (and most shells) is done without the special character $, you only prepend the $ to the variable name when you want the shell to give you the value contained within the variable (MY_VAR=”Some value”; echo “$MY_VAR”).
4. Google is your friend, if you have questions there are literally millions of pages of answers found on google!

Good call linking to tldp (The Linux Documentation Project http://tldp.org/ ). It’s been rather a while since I checked it out — and it looks like the material is now being updated more regularly (for a while it was kind of lagging). I highly recommend it. It’s a really great site for anyone able to study on their own, from newbie to guru.
