Module Release March 2002: Use Unix Streams, Pipes and Redirects, etc.

This month's Linux training materials release, actually contains three modules. The key new module covers use of unix streams, pipes and redirects.

The other 2 modules constitute a complete introduction to the entire Linux Professional Institute Level 1 Exam course, i.e. the course which all current releases are aimed at.

The first introductory module is simply an overview of fundamental Unix concepts and philosophy, i.e. the minimum ideas you need to grasp in order to understand how and why Unix commands and services work the way they do. Topics include: Unix System Architecture; the Linux Command Line; Logging In and Out; Command Syntax; Creating viewing, listing, copying, deleting and renaming files; Unix Command Feedback; Filename Completion, and; Command History.

The second introductory module, entitled "Getting Started", takes the newcomer on from fundamental ideas to a minimal set of practical commands you need to operate a Unix system and to progress through the rest of the course. Topics covered, include: Files and Directories; Absolute Paths; the Current Directory; Making and Deleting Directories; Relative Paths; Special Dot Directories; Hidden Files; Paths to Home Directories; Looking for Files in the System; Running Programs; Specifying Multiple Files; Finding Documentation for Programs; Specifying Files with Wildcards; Chaining Programs Together; Using Graphical and Text Interfaces.

The third module in this month's release is intended to meet the Linux Professional Institute's Objective 1.3.4.:

Connect files to commands and commands to other commands to efficiently process textual data. Includes redirecting standard input, standard output, and standard error; and piping one command's output into another command as input or as arguments (using xargs); sending output to stdout and a file (using tee).
