How to open a clone of the current tab in terminal with a simple command

instructions.txt

1) Put terminal_clone_tab.sh somewhere in 
   your path and make sure it is executable
     chmod u+x terminal_clone_tab.sh
2) Then add the following alias (~/.bash_profile or something)
     alias nt='terminal_clone_tab.sh'
3) Then you can hit nt (for new tab) anywhere
   and a new tab will open up in same directory.

If there is an easier way to do this, let me know [email protected].

terminal_clone_tab.sh

#!/bin/sh
osascript <<-eof
  tell application "Terminal"
    tell application "System Events" to tell process "Terminal" to keystroke "t" using command down
    do script with command "cd `pwd`; clear" in  selected tab of the front window
  end tell
