UNIX Command Line And The History Of The Shell

Mastering shell prompt can save tons of time. From the article:

The way you interface with a computer is changing constantly. Operating systems that once started as a command line-only interface have moved to a graphical front end. But moving away from what made the operating system great isn't always a step in the right direction. The IBM® AIX® operating system has kept to what's important: stability, functionality, robustness. And it has done it by keeping a strong command-line interface (CLI). If you never learned to use the CLI or need a refresher on its basics, read on.

After reading this article, you should now be able to use the Korn shell in ways you may not have known before. Mastering the command line can simplify your work and help you better understand how to make the shell and command line work for you rather than you working harder for it.
