.bashrc file with useful shortcuts. The file can update itself using `updaterc`. Also contains detection of platform it's running on

.bashrc

jakubboucek - thanks, I know. The reason for this is that I just like writing home to get home. Some gameservers like minecraft etc. use \home to teleport player to home location and I'm used to it. Also I have similiar shortcuts to music, downloads etc. so I have home so its consistent.

Nice, I will share some of my tips:

• Check https://github.com/clvv/fasd if you want to speed up directory navigation.
• Mac's uname returns Darwin. You can use cd - instead of cd $OLDPWD.
• May be it is enough to have one cd .. alias and chain them ..;..;...

Something I have learnt only recently (regrettably) - sharing prompt history among multiple terminals:

PROMPT_COMMAND="history -a; history -n"
shopt -s histappend

You may want to force editor to be used in more applications:

export EDITOR=nano
export VISUAL=$EDITOR

Well it should actually read vim and not nano ;-) There is even more fun hidden in .vimrc - https://github.com/brablc/dotvim . You are still young and can become vim hero (unlike me).
