zsh을 써서 cd를 안써도 되긴 하지만, 프로젝트까지 가는 뎁스가 길 때는 귀찮다. 그럴 때 쓰는 오토쩜프!

0. 맥에서

1. $ brew install autojump

==> Downloading https://homebrew.bintray.com/bottles/autojump-22.3.0.el_capitan.bottle.tar.gz

==> Pouring autojump-22.3.0.el_capitan.bottle.tar.gz
==> Caveats
Add the following line to your ~/.bash_profile or ~/.zshrc file (and remember
to source the file to update your current session):
  [[ -s $(brew --prefix)/etc/profile.d/autojump.sh ]] && . $(brew --prefix)/etc/profile.d/autojump.sh

If you use the Fish shell then add the following line to your ~/.config/fish/config.fish:
  [ -f /usr/local/share/autojump/autojump.fish ]; and . /usr/local/share/autojump/autojump.fish

zsh completion has been installed to:
  /usr/local/share/zsh/site-functions
==> Summary
🍺  /usr/local/Cellar/autojump/22.3.0: 18 files, 165.6K

2. .zshrc 또는 .bashrc에 하라는데로 적음

#.zshrc
[[ -s $(brew --prefix)/etc/profile.d/autojump.sh ]] && . $(brew --prefix)/etc/profile.d/autojump.sh

3. 설정

$ j # 점프 돌아다기 (두개 정도만 되는듯)
$ j -h # 도움!
$ j -s # 가중치 리스트 볼 수 있음
$ j -i # 현재 디렉토리 가중치 올리기
$ j [디렉토리 이름]
