We've all been there. + +Instead of killing the terminal you can use an ssh escape sequence to terminate the session. The sequence we want is `~.` (tilde and period). + +First key Return, then key the sequence `~.`. Your terminal is free! + +This isn't the only ssh escape sequence. To see others open an ssh session to a remote system and key `~?`, you will be presented with this message +``` +Supported escape sequences: + ~. - terminate connection (and any multiplexed sessions) + ~B - send a BREAK to the remote system + ~C - open a command line + ~R - request rekey + ~V/v - decrease/increase verbosity (LogLevel) + ~^Z - suspend ssh + ~# - list forwarded connections + ~& - background ssh (when waiting for connections to terminate) + ~? - this message + ~~ - send the escape character by typing it twice +(Note that escapes are only recognized immediately after newline.) +``` + +On occasion I use `~.` when I experience network drop out. I have used `~^Z` before to suspend my ssh session, useful when you want to leave jobs running and don't have screen or tmux available (see my post "[this ssux](20220331-this_ssux.html) on how I use tmux with ssh). + +The other escape sequences I have not used, but it is good to know they are there.
