Setup a New Laptop Environment

Setup a New Laptop

I always want to have the same work environment/setup on my desktop/laptop. Here’s just a quick notes for what I usually need on my work station.

Homebrew (MacOS only)

1	/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

(Optional) Install GPG package.

1	brew install gnupg

More info: https://docs.brew.sh

SSH

Generate New SSH Keys

Open terminal

Generate a new SSH key

1	ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

Different Keys for Different Servers

Create ~/.ssh/config file and add necessary info:

Host github.com
  User jocodoma
  IdentityFile ~/.ssh/github_rsa_jocodoma

Host gitlab.com
  User joseph
  IdentityFile ~/.ssh/gitlab_rsa_joseph

Host git-codecommit.*.amazonaws.com
  User XXXXXXXXXXXXXXXXXXXX
  IdentityFile ~/.ssh/codecommit_rsa

Different Keys for the Same Server

To manually specify a private SSH key to use for git

1	GIT_SSH_COMMAND='ssh -i ~/.ssh/private_key_file' git clone user@host:repo.git

To avoid typing GIT_SSH_COMMAND every time, you can set core.sshCommand for a specific repo
1
git config --local core.sshCommand "ssh -i ~/.ssh/private_key_file"

Git Settings

Get config files.

1 2	cd ~/Documents/ git clone git@github.com:jocodoma/config.git

(For bash only) Setup git scripts, including auto completion of git command.

~/.bash_profile

### My Settings ###

# Git completion
source ~/Documents/config/gitConfig/git-completion.bash

# Change command prompt
source ~/Documents/config/gitConfig/git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1
# '\u' adds the name of the current user to the prompt
# '\$(__git_ps1)' adds git-related stuff
# '\W' adds the name of the current directory
#export PS1="$purple\u$white\$(__git_ps1)$green \W $ $reset"
export PS1="$purple\u $yellow(@_@) $cyan\@$white\$(__git_ps1)$green \W # $reset"

# sublime text 3 alias
