README

evil.sh (aka. devili.sh)

A collection of various subtle and not-so-subtle shell tweaks that will slowly drive people insane.

Feel like trolling a colleague? Just add source ~/evil.sh to their .bash_profile and watch the chaos ensue. Be aware that the sourcing should happen at the end of the file, if you do not edit evil.sh before doing so, as evil.sh disables alias and unalias.

Contributions

Evil suggestions and pull requests are welcome. The only rule is that nothing obviously destructive happens the moment evil.sh is sourced. Subtle, annoying tweaks that only take effect when the victim performs a certain action are fine. On the other hand, a patch that adds rm -rfv / to evil.sh will be rejected.
