A Basic Introduction to Blogging
Web logging first appeared on the net in the mid-1990s. The term "web log" was initially coined refer to a server's log file and then expanded to include the meaning of online personal journaling. Later on, to avoid confusion, the word "blog" was adopted to refer to personal journaling. Today a blog is defined as an online publication where an author puts his or her personal thoughts and opinions from the most intimate to corporate ideas, concerns or events, in chronological order on the net.

Intro to UNIX Shells
A UNIX Shell is in simplest terms, a command line interpreter, that takes the users input and gives it to the Kernel. If you are familiar with DOS, you will remember the 'command.com' that file takes the users information and passes it to the operating system in a way it can be understood by the system. With DOS you only had one type of shell, but with UNIX you have a variety, each with their own abilities, pluses and minuses.
Keep in mind as you read about these shells, that though they may have major differences when they were created, that they have been updated and many features that were once only available in a single shell, may be available in other shells. This is more of a history lesson.
'sh'
The Bourne shell, named after its creator Steve Bourne is the oldest shell for most major distributions of UNIX and LINUX. Most shells today are in some fashion derived from the Bourne shell.
'csh'
The C Shell. The C shell is a great shell that has many advantages over the original Bourne shell, it was the first to introduce a history (the ability to scroll up, to view past commands). Also the C Shell as the name implies also integrates a great portion of the C programming language. If you are able to program in C, you can pretty much do it all in a shell script or from the command line, if you so desired.
