Please wrap all code, files, input & output/errors in CODE tags.
It makes it far easier to read and preserves spaces for indenting or fixed-width data.

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).
