openssh unix dev - Feb 2010 - ssh feature - ignore colon in host name

sorry if this has been discussed and rejected before, I'm new to the
list, I did google but didn't find anything.
--

quite often I use ssh and scp within a few minutes, so I might do this...

   scp myfile user at host.example.com:
   ssh user at host.example.com

it would make life a lot easier if I could type
   scp myfile user at host.example.com:
   ssh !$

or sometimes I simply copy too much and paste in host name and then have
the faff of removing it. ok, that's a particularly bad example of being
lazy :-)

for the above to work, ssh would have to ignore the colon, that's all. I
don't think the colon can have any significance in the hostname, so
throwing it away wouldn't be harmful!?

I could write a wrapper script, but I'm lazy, and figured it would be
nicer if ssh could simply have this quick hack... please


thanks for your time
Paul

What about [Esc]-[.]. This would display the last argument of the
previous command. You would then just have to remove the colon with
backspace, for instance.

It has in IPv6 addresses.

This, as others have mentioned, does not belong in ssh.

However, you can very easily do this without creating a wrapper script. 
Just add the following to your .zshrc (or rewrite for other shells):

function ssh()
{
     /usr/bin/ssh $@[1,-2] ${@[-1]%:}
}

This will invoke (the real) ssh with all the positional arguments, 
except ":" will be removed from the last argument, if present.

No extra files needed, no wrapper scripts, no measurable performance 
hit, standard ssh software.

Better solution in my book :)
