Over the past few months I have been using a community version of bashprofile, bashlogin, emacs settings and such. It started when Muness shared his bash_vcs (which was pimped command prompt) and I was hooked. I noticed a few projects that were sharing similar shell settings and enhancements. Forking from Toby’s dotfiles I started enhancing my experience on every machine I worked. This not only lead me to have a better understanding how different flavours of Unix work and also helped me automate a lot of my day to day activities.
Allow me to introduce the dotfiles project which comes with all those enhancements - stolen and tweaked from many sources - and with valuable help from Patrick Turley. Recent additions include bash_boost and what could be called the beginnings of a javavm (inspired by rvm for ruby.) Now with more brainpower behind dotfiles we hope to add more features fast. Next steps include adding support for zsh.
Give it a try, fork it or point us to more stuff we can steal to improve it for you.
