Bash Freeze, Control+s and Dead Terminals

Posted on 19 February 2003 by Demian Turner

Have you ever been typing away at the command line (this article presumes Bash) and all of a sudden everything freezes?  I don’t mean the usual network failures, modem disconnects and hung servers, I mean just some wrong key you hit while typing.

If you take the time to probe deeper into the mystery, you’ll find this common hangup is down to having hit control+s, probably accidently, which is Bash’s way of doing a scroll lock.  But how do you get out of it?  The terminal seems to be irrecoverable, right?
