• Pretty prompt

  # Start colored text with:
  #   %F{red}
  # End colored text with:
  #   %F{red}
  # %n    : user name
  # %m    : computer name
  # %/    : current dir
  export PS1='%n@%m:%F{red}%/%f $ '
  
  alias ls='ls --color'

• Aliases
  • Docker aliases

    # Docker
    export DOCKER_CONTEXT="lima"
    alias dmg="docker images"
    alias dps="docker ps --format 'table {{.ID}}\t{{.Image}}\t{{.Status}}\t{{.Names}}\t{{.Ports}}' $@"
    alias dst='docker stack "$@"'
    alias dsv='docker service "$@"'
    alias dsl='docker-stack-logs "$@"'
    alias dex='docker-exec $@'
    dsh() { docker-exec -ti $@ sh; }
    dbash() { docker-exec -ti $@ bash; }

  • rmforsure

    alias rm='echo "Warning: Use \"rmforsure\""'
    alias rmforsure='/usr/bin/rm'

  • pbcopy

    alias cpwd='echo -n $PWD | pbcopy'

• Navigation aids

  pushd()
  {
    if [ $# -eq 0 ]; then
      DIR="${HOME}"
    else
      DIR="$1"
    fi
  
    builtin pushd "${DIR}" > /dev/null
  }
  
  pushd_builtin()
  {
    builtin pushd > /dev/null
  }
  
  popd()
  {
    builtin popd > /dev/null
  }
  
  alias cd='pushd'
  alias pd='popd'
  alias td='pushd_builtin'
  
  # Shortcuts
  alias ll='ls -lah'

• Faster nvm

  [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" --no-use # This loads nvm

• Terminal key bindings(jump by word, go to home/end, delete all)

  autoload -U up-line-or-beginning-search
  zle -N up-line-or-beginning-search
  autoload -U down-line-or-beginning-search
  zle -N down-line-or-beginning-search
  
  bindkey -- "^[[A" up-line-or-beginning-search
  bindkey -- "^[[B" down-line-or-beginning-search
  
  bindkey -- "^[[1;3D" backward-word
  bindkey -- "^[[1;3C" forward-word
  
  bindkey -- "^H" backward-kill-word

  • Stop at "/" character

    WORDCHARS=${WORDCHARS/\/}
    WORDCHARS="$WORDCHARS\""
