A whole bunch of great bash functions to install stuff on MacOSX

install.sh

# Install a .app, .pkg or a .dmg with ease
function install() {
  if [[ "$1" =~ ^http ]]; then
    # Fix download using expect wrapping lwp-download
    # lwp-download is the only tool that gets any remote file name correct, unfortunately it is highly interactive and relies on user input
    echo "not reliable atm"
  else
    case $1 in
      *.dmg)
        install_dmg "$1"
        ;;
      *.app)
        install_app "$1"
        ;;
      *.prefPane)
        install_prefPane "$1"
        ;;
      *.pkg)
        install_pkg "$1"
        ;;
      *)
        echo "Unknown file or url given"
        return 1
    esac
  fi
}

# Mounts a disk image and tries to find a pkg or app to install, then unmounts
function install_dmg() {
  mountpoint=$(hdiutil mount "$1" | tail -n 1 | sed -e 's/.*\(\/Volumes.*\)/\1/')
  installable=$(find "$mountpoint" -name '*.app' -or -name '*.pkg' -or -name '*.prefPane' -maxdepth 1 | head -n1)
  if [[ "$installable" != "" ]]; then
    install "$installable"
  fi
  hdiutil unmount "$mountpoint"
}

function install_app() {
  cp -R "$1" /Applications/
}

function install_prefPane() {
  cp -R "$1" ~/Library/PreferencePanes/
}

function install_pkg() {
  sudo installer -pkg "$@" -target "/"
}

Great idea

Note: I've updated the gist. For now I have removed the download feature, since it was causing troubles with detecting the correct remote file name.

I also fixed a problem in the install_app function.

I've added install_prefPane to install preference panes.

Everything else should be working fine. Please report if you experience any inconveniences.
