Reload Chrome then refocus iTerm

reload_chrome.sh

#!/bin/sh
exec <"$0" || exit; read v; read v; exec /usr/bin/osascript - "$@"; exit

-- the above is some shell trickery that lets us write the rest of
-- the file in plain applescript

tell application "Google Chrome"
  activate
  tell application "System Events"
    tell process "Google Chrome"
      keystroke "r" using {command down, shift down}
    end tell
  end tell
end tell

tell application "iTerm" to activate

I have extended your script with params for app name and delay (that solves issues with PhpStorm, when used as external tool with keyboard shortcut) see https://gist.github.com/dennschu/0934c0945e4f0696ecd1
