Git

⬇️ Can be installed with Brew

Git user config

git config --global user.name 'Marie-Helene Mai'
git config --global user.email '[email protected]'

Git aliases

git config --global alias.co 'checkout'
git config --global alias.cob 'checkout -b'
git config --global alias.br 'branch'
git config --global alias.brm 'branch -m'
git config --global alias.brd 'branch -d'
git config --global alias.brD 'branch -D'
git config --global alias.cm 'commit -m'
git config --global alias.st 'status -sb'
git config --global alias.ll 'log --oneline'
git config --global alias.last 'log -1 HEAD --stat'
git config --global alias.rv 'remote -v'
git config --global alias.d 'diff'
git config --global alias.gl 'config --global -l'
git config --global alias.se '!git rev-list --all | xargs git grep -F'

• git status -sb displays the state of the working directory and the staging area in a more concise way

• git checkout -b <new_feature_branch> creates a new branch <new_feature_branch> from the current one and checks out to it

• git branch -m <new_branch_name> renames the current branch to <new_branch_name>

  

• git log --oneline lists the commits history in single line

• git config --global -l lists all the global configs

• git fetch -p && for branch in $(git for-each-ref --format '%(refname) %(upstream:track)' refs/heads | awk '$2 == "[gone]" {sub("refs/heads/", "", $1); print $1}'); do git branch -D $branch; done removes the local branches that not matching ins the remote

Git rebase

Rebasing a branch puts your commits on top the base branch. This allows to keep a clean history and helps investigating regression when checking git log.

git rebase <base>

Steps

• Create a <new_branch> from the <base>
• Checkout to the <base>
• Add additional commits
• The <new_branch> is now behind the <base>
• Checkout <new_branch>
• Run git rebase <base>, fix the conflicts if any and continue until the HEAD is ahead of <base>

git rebase -i|--interactive

iTerm2 terminal

⬇️ Can be installed with Brew

Auto-suggestions with zsh

• Install Oh My Zsh

  sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
  

• Install the zsh-autosuggestions plugin

  git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
  

• Add the plugin in the zsh config file

  • Open the file vim ~/.zshrc.
  • Find the line starting with plugins= that contains other plugins and add the zsh-autosuggestions plugin.

    💡 In vim navigation mode, you can type /plugins= to search the nearest occurrence of plugins= then n to go to the next.

  plugins=(
    ...
    zsh-autosuggestions
  )
  

  • Exit vim insertion mode ESC then :wq to save and quit.

• Apply the changes source ~/.zshrc.

• Start typing any command in the terminal. You should now see the suggestion and using → key will confirm the suggestion.

Natural Text Editing

💡 This allows you to benefit from some shortcuts to navigate easier in the terminal that are not available by default by iTerm2.

• Go to iterm2 > Preferences > Profiles > [Profile Name | default] > Keys > Presets

Editing shortcuts

• ⌥← jumps to previous word
• ⌥→ jumps to next word
• ⌃← jumps to start of line (can conflict with Spectacle shortcuts, can use default terminal ⌃a instead)
• ⌃→ jumps to end of line (can conflict with Spectacle shortcuts, can use default terminal ⌃e instead)

Tab/Pane Switching shortcuts

• ⌘D creates a new pane horizontally
• ⌘⇧D creates a new pane vertically
• ⌘[ switches to previous pane
• ⌘] switches to next pane
• ⌘T creates a new tab
• ⌘⇧← moves current tab to left
• ⌘⇧→ moves current tab to right
• ⌘⇧[ switches to previous tab
• ⌘⇧] switches to next tab
• ⌘1|2|n switches to tab 1|2|n

Common bash/zsh commands and shortcuts

• ⌃r [previous_command_to_search] gets the first matching entry in the history. By repeating ⌃r, it gives the following matching entries.

• ⌥⌫ deletes word by word

• ⌘⌫ deletes whole line

• find [path from where to start the search] [-options] [what to find] searches files or directories

• which locates a command by searching the executable in the directories specified by the PATH
