If you're going to go into stty raw mode and then try to get back to where you were before by using other stty commands, it is usually better to save the old settings and restore them exactly as they were initially with something like:

Code:

saveterm=$(stty âˆ'g)	# save terminal state
stty (new settings)	# set new state
... 			# do whatever you want in the new terminal state
stty $saveterm		# restore original terminal state

Note that this is one of those places where it is important that you not enclose the expansion of $saveterm in double-quotes.

Hoping that you will get back to where you started just by using modes like cooked or sane always have a good chance of missing something that was important to the user who set up his/her terminal session before your script "messed with it".
