Wow, never knew this... That said I'm not sure if I'll remember using it as my muscle memory is already trained to kill hung processes via ctrl-b s, ctrl-k, ctrl-b x (in tmux).

Hidden or undocumented features like this always have a strange appeal. Part of it is nostalgia for older software where small Easter eggs or experimental features would sometimes ship in production builds.

It's not hidden or undocumented; it's in the man page.

Here's 15-year old HN link about it: http://grack.com/blog/2011/02/23/ssh-escape-sequences-or-don...

Secret Menu -> Escape Characters

I really hate it when people just rename terms. It made it harder to search properly for better answers.

FYI, you can kill forwarding tunnels with -KD portnum in that commandline too.

That doesn't do much good if you set `EscapeChar` to `none` in `.ssh/config`.

I find it convenient not to have to worry about accidentally entering escape characters. YMMV.

Note that it only works after pressing enter, so the odds are slim. In practice, I don't think I ever hit it by accident.

I have noticed it while running ~/bin/some_command. The ~ doesn't echo until I also type the /. It doesn't cause any misbehavior because there is no binding for ~/ but can be slightly surprising.

I find it odd that you would have commands in ~/bin but not have it be the highest priority in your PATH. I use ~/.local/bin, but would never type it because i wouldn't have bins that overlap shell commands and no other path would have priority.

Usually, it is. IIRC, this was when I was just setting up my environment on a new host, after I had populated ~/bin but before I restarted my shell to pick up PATH modifications.

SSH does it pretty well though. Never once have I done it by mistake.

I'd guess this is because it only works in ssh PTY sessions. So it would have no effect on tunneling or when piping arbitrary data through ssh to a non-interactive remote command (unless you use the -t switch to force PTY allocation even when stdin is not a TTY).

No I don't think so. I mainly and pretty much constantly use SSH for logging in. I'm not one of those 'cattle not pets' guys lol.

And when I port forward I usually don't even tunnel it over SSH because all my stuff is on tailscale so it's also encrypted.
