This is disabled by default, but can be enabled via:

  • The -exec-prefix='!!' flag.
  • The built-in !hostcmd !! binary.

The result of either of these will be that commands can be executed on the host by prefixing them with !!. A different prefix may be selected, of course.

This will close #173.

Sample run:

A>!!
!!?
A>!hostcmd !!

A>!!uptime
 14:41:19 up  1:20,  1 user,  load average: 0.68, 0.58, 0.54


A>!hostcmd
The command-prefix for executing commands on the host is '!!'
(An empty value means that host-execution is disabled.)

A>!hostcmd exec-

This is disabled by default, but can be enabled via:

* The `-exec-prefix='!!'` flag.
* The built-in `!hostcmd !!` binary.

The result of either of these will be that commands can be executed
on the host by prefixing them with `!!`.  A different prefix may be
selected, of course.

This will close #173.
