			==Try also reptyr==
			[https://github.com/nelhage/reptyr reptyr] acts the same as retty but is also available on 64-bit platforms while retty is only for i386.
			==Ubuntu==
			Note that to use retty or reptyr on recent Ubuntu you've to allow any process to debug another process, which is not allowed by default (only children of a process can be debugged by it):

Always check first if attaching given application works before you will do it for real.

			Example:
			* Run top in e.g. a xterm
			* Find its PID
			* in another term, type "retty <PID>"
			* to quit properly, go to another term and kill nicely retty, top will be attached back to its original tty

			Another example: you want to run a process detached
			* "top &" ? Nope this fails and top stops immediately
			* "nohup top"? Nope this fails with "top: failed tty get"
			* Try "setsid blindtty top"
