• brew install pinentry-mac
• echo "pinentry-program /usr/local/bin/pinentry-mac" >> ~/.gnupg/gpg-agent.conf

Conditional Git Config

Load Git config depending on repo path

[user]
    name = zk
    email = [email protected]
    signingkey = foobar
    gpgsign = true
[alias]
    cp = cherry-pick
    pr = pull --rebase
[includeIf "gitdir:/Users/zk/dev/github.com/**"]
    path = /Users/zk/.gitconfig-zk
[includeIf "gitdir:/Users/zk/dev/github.work/**"]
    path = /Users/zk/.gitconfig-work

Macro

Kill Docker

function whaling() {
  ps ax|grep -i docker|egrep -iv 'grep|com.docker.vmnetd'|awk '{print $1}'|xargs kill
}

Force restart Logitech Mouse Daemon

function mouse() {
  ps ax|grep -i Options.app/Contents/Support/LogiMgrDaemon.app/Contents/MacOS/LogiMgrDaemon|egrep -iv 'grep --color=auto --exclude-dir'|awk '{print $1}'|xargs kill
}

JWT Decoder

function jwtd() {
    if [[ -x $(command -v jq) ]]; then
         jq -R 'split(".") | .[0],.[1] | @base64d | fromjson' <<< "${1}"
         echo "Signature: $(echo "${1}" | awk -F'.' '{print $3}')"
    fi
}

Misc

Display the current kubectx as iTerm2 Badge:

• install iTerm2 Shell Integration: wget https://iterm2.com/misc/install_shell_integration.sh
• to prevent misconfiguration adapt the script do directly detect zsh as your shell (line 10)
• execute install script (chmod +x ...)
• append following function to .zshrc right after source iterm_shell_integration

function iterm2_print_user_vars() {
  iterm2_set_user_var kube_context $(kubectl config current-context 2>/dev/null)
  iterm2_set_user_var kube_ns $(kubectl config view --minify --output 'jsonpath={..namespace}'; echo)
}

• go to iTerm > Preferences > Profiles > General and set \(user.kube_context)\n\(user.kube_ns) as badge
• I recommand to re-init zsh the the very end of .zshrc

Install GnuCoreUtils with g-prefix

• brew install coreutils findutils gnu-tar gnu-sed gawk gnutls gnu-indent gnu-getopt grep
  If you want to use them without g-prefix, adjust your PATH and MANPATH (add before anything else).

PATH="/usr/local/opt/coreutils/libexec/gnubin:$PATH"
MANPATH="/usr/local/opt/coreutils/libexec/gnuman:$MANPATH"
