The UNIX command line shell (bash) with it's many tools and possibilities is a very powerful but less and less used system. Harald Koenig will show interactively and step by step how to solve a problem "on the command line".
After solving "the problem of the day" you save your solution to a small shell script and create a new tool to solve this (or similar) problems in the future.

Creating more and more such small helper tools will make your own toolbox more usable and sophisticated and thus your daily work easier and more efficient.

Possible topics for a small script might be
- get fuel prices for your local fuel stations, store them and them with gnuplot
- analyze syslog entries for ssh breakin attempts, do some statistics and send complaint emails
- how to use XML, JSON, CSV etc. with shell tools
- modify binary files
- other ideas? email me your suggestions in advance!!
