The terminal settings didn't get corrupted that way though, which suggests that it isn't 'less' that messes things up. > Also, the OP said the problem was happening on pipelines like 'tail | grep'. > Neither tail nor grep muck with tty settings (that I know of) Yep, a look at their sources confirms that. > so if the tty is ending up with echo disabled, > it's got to be the shell leaving it that way.

Also, for anyone who sees the issue again, blindly typing just 'stty' (without the 'sane') and posting the output here might provide a clue.
