ssh escape characters
1 ESCAPE CHARACTERS
2 When a pseudo-terminal has been requested, ssh supports a number of functions through the use of an
3 escape character.
4
5 A single tilde character can be sent as ~~ or by following the tilde by a character other than those
6 described below. The escape character must always follow a newline to be interpreted as special. The
7 escape character can be changed in configuration files using the EscapeChar configuration directive or on
8 the command line by the -e option.
9
10 The supported escapes (assuming the default ‘~’) are:
11
12 ~. Disconnect.
13
14 ~^Z Background ssh.
15
16 ~# List forwarded connections.
17
18 ~& Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate.
19
20 ~? Display a list of escape characters.
21
22 ~B Send a BREAK to the remote system (only useful for SSH protocol version 2 and if the peer sup‐
23 ports it).
24
25 ~C Open command line. Currently this allows the addition of port forwardings using the -L, -R and
26 -D options (see above). It also allows the cancellation of existing port-forwardings with
27 -KL[bind_address:]port for local, -KR[bind_address:]port for remote and -KD[bind_address:]port
28 for dynamic port-forwardings. !command allows the user to execute a local command if the
29 PermitLocalCommand option is enabled in ssh_config(5). Basic help is available, using the -h
30 option.
31
32 ~R Request rekeying of the connection (only useful for SSH protocol version 2 and if the peer sup‐
33 ports it).
34
35 ~V Decrease the verbosity (LogLevel) when errors are being written to stderr.
36
37 ~v Increase the verbosity (LogLevel) when errors are being written to stderr.
