You have Zsh and want to use aliases and functions like

• l instead of ls -lah
• q instead of wget http://speedtest.wdc01.softlayer.com/downloads/test100.zip --output-document=/dev/null to get your internet speed

• Getgit, curl, a unix like OS and Zsh
• Get Oh-My-Zsh[(https://github.com/ohmyzsh/ohmyzsh)] with sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
• Fork this repo
• Get to know my custom plugin common-aliases.zsh
• Edit .zshrc with e.g. plugins=(git) to only load the git plugin

• Used version Zsh: 5
• Oh-My-Zsh has lots of useful plugins
• Refresh/reload Zsh command after change: exec zsh
