About ZSH

The Z shell (Zsh) is a Unix shell that can be used as an interactive login shell and as a command interpreter for shell scripting. Zsh is an extended Bourne shell with many improvements, including some features of Bash, ksh, and tcsh. (from christitustech with some new features, improvements and fixes).

wget https://github.com/Amirmohammadomidi/zsh/raw/master/.zshrc -O ~/.zshrc
mkdir -p "$HOME/.zsh" && mkdir -p "$HOME/.cache/zsh" && touch "$HOME/.cache/zsh/history"
wget https://github.com/Amirmohammadomidi/zsh/raw/master/.zsh/aliasrc -O ~/.zsh/aliasrc
