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

.bashrc

@stekycz I've added platform detection to the file. You should be able use the colored ls now. I'll be glad if you let me know if you let me know when you found any other diferences between linux and Mac so I can improve the script.

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).
