1. Command Line Productivity
2. Why?
4. Learn your tools
5. Keep a (hand-written!) cheat sheet
6. LaunchBar
9. Put your dotfiles in Git gitlab.com/nuclearsquid/dotfiles
10. Comment everything extensively
11. pbcopy & pbpaste
12. Brewfile brew bundle
13. Git
14. Machine-specific config [include] path = ~/.gitconfig.private
15. Git aliases
16. Only add the changes you want git config --global alias.ap 'add --patch'
17. Diffing git config --global alias.d 'diff --ignore-all-space' git config --global alias.dc 'diff --cached --ignore-all-space' git config --global alias.wd 'diff --word-diff="color"' git config --global alias.wdc 'diff --word-diff="color" --cached'
18. git stash
19. ; Inspect history in various ways news = log -p HEAD@{1}..HEAD@{0} ; Show compact history l = "!git log -10 --graph --pretty='tformat:%C(yellow)%h{%C(green)%ar\ {%C(bold blue)%an{%C(red)%d%C(reset) %s' $* | column -t -s '{' | less -FXRS" ; Show commit log using graph notation lg = log --color --graph --pretty=format:'%Cred%h%Creset \ -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' \ --abbrev-commit --date=relative ; List commits showing changed files ll = log --pretty=format:"%C(yellow)%h%Cred%d\\ %Creset%s%Cblue\\ [%cn]" \ --decorate --numstat
22. git-rerere
23. Emacs editor commands • Ctrl-a (go to beginning of line) • Ctrl-e (go to end of line) • Ctrl-r (search backwards through history) • Alt-f (move cursor forward 1 word) • Alt-b (move cursor backwards 1 word)
24. ZSH
