This presentation will focus on the underutilized features of bash that are critical to building production quality scripts. Demos will show you how to turn on options and error trapping that expose the hidden time bombs in the code.

Turning these features on should be considered a requirement, much like turning on “strict” and “warnings” is considered a requirement for Perl programs.

Also, as much of the bash syntax has become outdated, the presentation will explain which syntax is best to use and which syntax to avoid.

Knowledge of any of the common UNIX scripting languages will be sufficient to understand the presentation and script authors at all proficiency levels should find value in attending. Although the presentation does not address differences between Korn shell and bash, much of what will be discussed also applies to Korn shell.
