Say you use :
sssh “param one with spaces” p2

$* will yield ssh -openblabla “param” “one” “with” “spaces” “p2″
“$@” will yield ssh -openblabla “param one with spaces” “p2″

You can also pass commands, so to reattach to a remote screen session you can do: ssh -tt firewall.example.com ssh -tt my-vm screen -x Another useful trick is “ssh -tt” which forces tty allocation, so instead of the above you can do the following:
ssh -tt firewall.example.com ssh -tt my-vm

Saves the need for the script and the little mental step of deciding to use a different ssh/scp/sftp call :) $ cat ~/.ssh/config Host gateway.company.com ProxyCommand none Host *.company.com my-private-host ProxyCommand ssh myuser@gateway.company.com nc -q0 %h %p $ See also the ProxyCommand ssh config option.

The -oproxycommand method will transparently deal with port forwards etc for you tho, which is nice. I can still pass any of the -X, -L, -R options and it just works. scp will work in the same way, so you can create another file "/usr/bin/sscp" and be able to copy files from remote hosts direct to your desktop via a firewall machine.
