# === Terminal.app === #
# Open new tab in terminal.
exec("osascript -e 'tell application \"System Events\" to tell process \"Terminal\" to keystroke \"t\" using command down' > /dev/null 2>&1 ")

# Open directory
exec("osascript -e 'tell application \"Terminal\" to do script \"cd directory\" in selected tab of the front window' > /dev/null 2>&1 ")

# Open directory in new tab (this is better)
exec("osascript -e 'tell application \"Terminal\"' -e 'tell application \"System Events\" to tell process \"Terminal\" to keystroke \"t\" using command down' -e 'do script with command \"cd directory && clear\" in selected tab of the front window' -e 'end tell' > /dev/null 2>&1")
