Tutorial Terminal and Git Customize at MacOS

As I spend a lot of time trying to configure my terminal and git, so they fit my preferences on macOS, I ended up doing these tutorials below.

---

On these tutorial you may use a text editor from terminal, for those users that have experience with, feel free to use your favorite one.

To users that doesn't use an editor on terminal, I suggest trying the nano, because its simple to use and install.

If you want nano follow steps below, otherwise jump to step 1.

• First installs Homebrew, a package manage for macOS.
• Open terminal (cmd + space and write terminal).
• Run brew install nano to install nano. So open a text file: nano path/to/file/name. To save and close, just press ctrl + x and enter.

Choose which step do you want, and roll until there:

1. Auto Completing

2. Terminal Color and Branch Indication

3. Changing git output colors

1. Auto Completing

• First install Homebrew, a package manage for macOS.
• Second opens terminal (cmd + space and write terminal):

  • On Terminal run brew install bash-completion

  • Open ~/.bash_profile.

  • Paste the come below at bash_profile:

  if [ -f $(brew --prefix)/etc/bash_completion ]; then
    . $(brew --prefix)/etc/bash_completion
  fi
  

  • Save and close ~/.bash_profile
• Run source ~/.bash_profile on terminal.
• Now when you press tab on a git command, it will auto complete.

2. Terminal Color and Branch Indication

• Open terminal (cmd + space and write terminal):

  • Open the file ~/.bash_profile

  • Paste at the end of bash_profile:

parse_git_branch() {
     git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/ (\1)/'
}

This "function" will get the branch that you are working.

• Now to change the Prompt String One (PS1), the string before each command on terminal, we have some different designs.
• Choose which PS1 do you want based on the pictures below, and copy the code related to the picture you want.

1. Design 1

export PS1="\u@\h \[\033[32m\] | \w\[\033[33m\] | \$(parse_git_branch)\[\033[00m\] \n $ "

```
User @ Computer | path until actual folder | branch
$ :
```

2. Design 2

  export PS1="\u@\h \[\033[32m\] | \W\[\033[33m\] | \$(parse_git_branch)\[\033[00m\] \n $ "

```
User @ Computer | actual folder | branch
$ :
```

3. Design 3

  export PS1="\u@\h \[\033[32m\] | \w\[\033[33m\] | \$(parse_git_branch)\[\033[00m\] $ "

```
User @ Computer | path until actual folder | branch $ :
```
- Paste after the function `parse_git_branch`.
- Save and close `~/.bash_profile`

• Run source ~/.bash_profile on terminal.

If you use Linux please check this tutorial

I suggest combine the commands on PS1 to fit your necessities, to understand all commands there and learn othesr check this link.

3. Changing git output colors

Although this tutorial focus on macOS users, this step also works on Linux!

• Open terminal (cmd + space and write terminal):
  • Run git command: git config --global -e
    • If you want to change your git editor run: git config --global core.editor "editor"
    • On "editor" put your preferable editor.
  • Paste the code below on it:

    [color]
        branch = auto
        diff = auto
        status = auto
            ui = true
    [color "branch"]
        current = yellow reverse
        local = yellow
        remote = green
    [color "diff"]
        meta = yellow bold
        frag = magenta bold
        old = red bold
        new = green bold
    [color "status"]
        added = yellow
        changed = green
        untracked = cyan
  

  As you can see this files setup the colors on git commands: branch, diff and status. You can search others commands or change the colors.
