OSX Terminal open in new tab

# Inspired from http://elsethenif.wordpress.com/2009/06/11/open-a-new-tab-on-terminal-with-the-same-path-on-mac-os-x/
# Put this in your ~/.bash_profile
# Added functinality to pass commands to the new tab
# Examples:
#    Open a new tab in terminal with the same path:
#      nt
#    Open a new tab with the same path, and pass command "script/server":
#      nt script/server
#    Open a new tab with the same path, list all files and navigate one directory up:
#      nt ls "cd .."
function nt {
	COMMANDS="
                tell application \"System Events\" to tell process \"Terminal\" to keystroke \"t\" using command down
                tell application \"Terminal\" to do script \"cd $PWD \" in selected tab of the front window
                tell application \"Terminal\" to do script \"clear\" in selected tab of the front window
	"
	for p in "$@"
	do
		append="tell application \"Terminal\" to do script \"$p\" in selected tab of the front window
		"
		COMMANDS="$COMMANDS$append"
	done
	osascript -e "$COMMANDS" > /dev/null 2>&1
