Open a new terminal tab from the current terminal using command A new terminal window can be opened by a command

open -na Terminal


Is there a way to open a new terminal tab?
You have to do this through AppleScript, but it can be executed from the command line via osascript

osascript -e 'tell application "Terminal" to activate' -e 'tell application "System Events" to tell process "Terminal" to keystroke "t" using command down'
