That way, you can avoid 'eval'.

You can find some examples, where using 'eval' is fine, in the ABS guide:


but you can also read there (and many other sources):
The command wont always be ssh. I want to keep the script as simple and compact as possible.

ssh-argv0

SSH-ARGV0(1)                                                BSD General Commands Manual                                               SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.  If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
