Trivial Utilities

`ssh-host`

It used to be that you could make a symlink to rsh:

          % ln -s /usr/local/bin/rsh potato

rsh would look at argv[0] and use that as the host name

So now you could type

          % potato

And it would act as if you had typed

          % rsh potato

ssh doesn't support that feature

But ssh-host does:

       parsnip% cat ~/bin/ssh-host
       exec ssh "$(basename $0)"

       parsnip% ln -s ssh-host ~/bin/potato
       parsnip% potato
