Linux In The Shell aims to explore the use of many commands a user can run in the Bash Shell. Tutorials include a write up with examples, an audio component about the write up, and a video component to demonstrate the usage of the command.
Welcome to the first entry of Linux in the Shell. Before delving into specific commands, redirection will be explored as redirection will be used frequently in the examples going forward. The Unix philosophy posits program simplicity and that a program should do one thing and do it well (Mike Gancarz, the Unix Philosophy). Eric Raymond adds the Rule of Composition: "Design programs to be connected to other programs." Redirection is the glue that achieves this design.
The website is http://www.linuxintheshell.com/
Redirection is applied to any of the following standard streams to achieve results beyond simply outputting some value from a single command:
Standard Input (stdin) – 0
Standard Output (stdout) – 1
Standard Error (stderr) – 2

Great show Dann. You spoke very clearly and were obviously prepared. Well done. Since shell stuff can be quite thick at times, maybe after every few minutes you should just take a breather to allow people to catch up. Maybe a joke or story or something. I liked all the philosophical stuff you started out with. Its good for beginners to hear all that.
