5 Real Sysadmin Work

5.1 Don’t create World-Writable Files

Finding things that are not symbolic links that have other write permissions:

find dir ! -type l -perm /o+w -ls

(You have one assignment that requires you to create world-writable files.)

5.2 Multiple Remote Login Sessions

You are now logging in to multiple machines. Set your shell PS1 prompt to include the machine name, so that you don’t type the wrong command on the wrong machine!

5.3 City of Munich dumps Microsoft for Linux

If you are only doing a migration because you think it saves you money there’s always somebody who tells you afterwards that you didn’t calculate it properly. That was the experience of a lot of open source-based projects that have failed. They were only cost-driven and when the organisation got more money or somebody else said ‘The costs are wrong’ then the main reason for doing it had broken away. That was never the main goal within the City of Munich. Our main goal was to become independent.


Free software was ruled the better choice by Munich’s ruling body, principally because it would free the council from dependence on any one vendor and future-proof the council’s technology stack via open protocols, interfaces and data formats.

The project finished within budget in October 2013, with more than 14,800 staff migrated to using Linux and more than 15,000 to OpenOffice.
