Noob Problem (sending CTRL + ] )

Ruby
1

Hi all,
I want to create a script which will execute the following tasks:
launch a console on a virtual server via libvirt:
virsh console NameOfTheServer
Log into the server
login \n
password\n
send a command inside the server
command
send CTRL + ]

I’m first not sure how to send the command after sending an os command.
and I definitely don’t know how to send the special key CTRL + ] (^])

Any ideas?

Thanks

Ctrl-] is “\x1d”.

I don not clearly understand what you want to do but maybe this
helps. I once wrote a tool that feeds the input queue with some
characters before executing another process. To use it write
something like:

fork {
$stdin.unget “login username\rpassword verysecret\rsomecmd\r\x1d”
exec “telnet otherhost 110”
}

And there you are. Notice that the enter key sends “\r”, not “\n”.
Here’s the source code:
