Setting Up a Mac Terminal

How to set up a mac terminal with a more humanistic user interface

1. Instal iTerm2

iTerm2 homepage

2. Instal oh-my-zsh

oh-my-zsh homepage

Run:

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

3. Instal must-have plugins

• zsh-autosuggestions
• zsh-history-substring-search
• zsh-syntax-highlighting

Clone the plugins into the oh-my-zsh directory. Run:

git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
git clone https://github.com/zsh-users/zsh-history-substring-search.git $ZSH_CUSTOM/plugins/zsh-history-substring-search

Instal the cloned plugins into oh-my-zsh. In ~/.zshrc, on your plugins array, insert:

  zsh-autosuggestions
  zsh-syntax-highlighting
  history-substring-search

4. Customize your prompt

References:

• Zsh Prompt Exapansion
• Bash Colors
• Bash String Interpolation

This part is totally up to you, but this is what I use. In ~/.zshrc, below source $ZSH/oh-my-zsh.sh, insert:

export PROMPT=$'\e[36m%n\e[92m:\e[93m%d $(git_prompt_info)'

5. Insert your custom functions and aliases

Different people have different needs, I've included below some of the things that works for me.

In ~/.zshrc, insert:

#   -------------------------------
#   1. ENVIRONMENT CONFIGURATION
#   -------------------------------

    #   Set Paths
    #   ------------------------------------------------------------
    #   This is where your path variables live. Some tools or runtimes requires this.

    #   Examples:
    # export PATH="/usr/local/opt/qt@5.5/bin:$PATH"
    # export PATH="/Library/Java/JavaVirtualMachines/jdk1.8.0_172.jdk/Contents/Home/bin:$PATH"
    # export PATH="/Users/tirtawr/Library/Python/2.7/bin:$PATH"
 
    #   Set Default Editor (change 'Nano' to the editor of your choice)
    #   ------------------------------------------------------------
    export EDITOR=/usr/bin/nano

    #   Set default blocksize for ls, df, du
    #   ------------------------------------------------------------
    export BLOCKSIZE=1k


#   ---------------------------
#   2. DEVELOPMENT RELATED
#   ---------------------------
#   This is where I tend to put some aliases or functions that helps me when I'm doing development.
# 
    #  Ruby
    #  ------------------------------------------------------------
    alias dbe="RAILS_ENV=development bundle exec "
    alias bed="RAILS_ENV=development bundle exec "
    alias tbe="RAILS_ENV=test bundle exec "
    alias bet="RAILS_ENV=test bundle exec "
    alias be="bundle exec "
    alias bers="bundle exec rails s"

    # Typo Protection
    #  ------------------------------------------------------------
    alias devleop="develop"
    alias cehckout="checkout"
    alias gut="git"
    alias doker="docker"

    # CD Into specific projects/directories
    #  ------------------------------------------------------------
    alias wsp="cd ~/Workspace"
    alias desk="cd ~/Desktop"
    alias ~="cd ~"

#   -----------------------------
#   3. MAKE TERMINAL BETTER
#   -----------------------------
#   These are some helpers that makes the terminal better

    alias cp='cp -iv'                           # Preferred 'cp' implementation
    alias mv='mv -iv'                           # Preferred 'mv' implementation

    alias cd..='cd ../'                         # Go back 1 directory level (for fast typers)
    alias ..='cd ../'                           # Go back 1 directory level
    alias ...='cd ../../'                       # Go back 2 directory levels
    alias .1='cd ../'.                          # Go back 1 directory levels
    alias .2='cd ../../'.                       # Go back 2 directory levels

    alias .4='cd ../../../../'                  # Go back 4 directory levels
    alias .5='cd ../../../../../'               # Go back 5 directory levels
    alias .6='cd ../../../../../../'            # Go back 6 directory levels
    alias f='open -a Finder ./'                 # f:            Opens current directory in MacOS Finder
    alias c='clear'                             # c:            Clear terminal display
    alias which='type'                          # which:        Find executables
    alias path='echo -e ${PATH//:/\\n}'         # path:         Echo all executable Paths
    mcd () { mkdir -p "$1" && cd "$1"; }        # mcd:          Makes new Dir and jumps inside
    trash () { command mv "$@" ~/.Trash ; }     # trash:        Moves a file to the MacOS trash
    ql () { qlmanage -p "$*" >& /dev/null; }    # ql:           Opens any file in MacOS Quicklook Preview
