Oh My Zsh

Powerful combo of Zsh + a bunch of useful plugins

Custom Aliases

alias y="yarn"
alias ys="yarn start"
alias yt="yarn test"
alias gcm="git checkout master"

Useful default aliases

l # alias for ls -alh
g # alias for git
gco # alias for git checkout
gss # alias for git status -s
gcb # alias for git checkout -b
glog # alias for git log --oneline --decorate --graph

Full cheat sheet: https://github.com/ohmyzsh/ohmyzsh/wiki/Cheatsheet or use the alias command to see all available aliases

Use `gcm` + `gco` when rebasing

gcm # checkout master
g pull # pull the latest master
gco - # switch back to your working branch 
g rebase master
g push -f

Use shortcuts

- # shortcut for cd - : go to previous directory
~ # shortcut for cd ~ : go home
sudo !! # reruns previous command with sudo prefix. can also be done using `the eff`

Autojump

Very useful plugin, not Zsh specific. Let's you jump to any directory that you've already visited using fuzzy matching. E.g.

j 2020 # jumps to ~/Projects/www-wrapped-2020
j mob # jumps to ~/Projects/client-web/open/mobile-web-player

The F****

The Eff, as I will call it in the interest of keep it PG, is a self described tool that "corrects errors in previous console commands". It's kind of like a command line linter

I change the alias from, literally, fuck to sure.

brew install thefuck
echo 'eval $(thefuck --alias sure)' >> ~/.zshrc

Example usage

➜ git push
fatal: The current branch master has no upstream branch.
To push the current branch and set the remote as upstream, use

    git push --set-upstream origin master


➜ sure
git push --set-upstream origin master [enter/↑/↓/ctrl+c]
Counting objects: 9, done.

Reverse search through command history

Not Zsh specific. Use ctrl + R

Alertnative to

Pressing up 1 million times
history | grep foo this is is a good option if you want to use regexs to search through mor e rows

iTerm2

cmd + d # create a new vertical session
shift + cmd + d # create a new horizontal session
cmd + t # create a new tab session

Settings

Enable option/alt + left || right moves the cursor across words

In Profiles > Keys, add the following

Enable "Reuse previous session's directory"

In Profiles > General > Working Directory, check "Reuse previous session's directory"

This means that whenever you start a new session using cmd + D, it puts you in the pwd of the last session

Workflow

I'll usually have one tab per "project/initiative", with one to four split session per tab, depending on the number of repos involved, e.g.

ys in the upper left
yt --watch in the lower left
zsh shell on the whole right half

Alertnative

Use tmux, which should actually work in conjunction with iTerm2.

VS Code

Follow the docs on launching from the command line. TLDR: cmd + P → seach for "install" → select "Shell Command: Install 'code' command in PATH"

This lets you open projects by doing

code .
