To gain a lot of time, you can replace the old “bash” by “zsh”, which is a very more powerful shell with autocompletion, but not only… It has a configuration file called “.zshrc” that you have to put in your home. You can try zsh by installing it and typing “zsh”, and if you’re convinced, keeping it by typing chsh and choosing /bin/zsh.

You have my entire .zshrc but I choose 3 snippets that I prefer to show you the usefullness :

As I use Fedora, Debian, and Ubuntu, I made this to type “i program” to install profram on any system, and “u” to update the system. 

#i for install, u for update

if [ -e /bin/yum ]; then

alias i="sudo yum install"

alias u="sudo yum update"

else

alias i="sudo apt-get install"

alias u="sudo apt-get update && sudo apt-get dist-upgrade"

fi

Force sudo for commands that anyway need it

alias yum="sudo yum"

alias apt-get="sudo apt-get"

alias service="sudo service"

Setting vi as default editor :

export EDITOR="vi"

The multiples ssh shorcuts

alias sshd="ssh mappam.dyndns.org -X"

alias sshc="ssh itstudents.be -X -L 3129:localhost:3129"

I use my zshrc on multiple system and multiple environment, hence you have some tricks and multiplications like different variables for the same program in the path variable.

#Using color schemes

autoload -U colors && colors
#Adding ADB to path variable

export PATH=${PATH}:/usr/src/android-sdk-linux/platform-tools/:/usr/src/android-sdk-linux/tools/:/opt/android/platform-tols/
