Escape Characters

When a pseudo-terminal has been requested, ssh supports a number of functions through the use of an escape character.

A single tilde character can be sent as ~~ or by following the tilde by a character other than those described below. The escape character must always follow a newline to be interpreted as special. The escape character can be changed in configuration files using the EscapeChar configuration directive or on the command line by the -e option.

The supported escapes (assuming the default '~') are:

~.' Disconnect.

~^Z' Background ssh.

~#' List forwarded connections.

~&' Background ssh at logout when waiting for forwarded connection / X11 sessions to terminate.

~?' Display a list of escape characters.

~B' Send a BREAK to the remote system (only useful for SSH protocol version 2 and if the peer supports it).

~C' Open command line. Currently this allows the addition of port forwarding using the -L, -R and -D options. It also allows the cancellation of existing remote port-forwardings using -KR[bind_address:]port. !command allows the user to execute a local command if the PermitLocalCommand option is enabled in ssh_config. Basic help is available, using the -h option.

~R' Request rekeying of the connection (only useful for SSH protocol version 2 and if the peer supports it).
