Put something that runs in the END { } block to print when it's dead or alive. Remember whether anything was found with a variable.
You've got quoting problems happening -- not just single quotes being needed for pipes, but that $1 is probably being interpreted as a shell variable somewhere along the line; the single quotes vanish once it gets to the other side of ssh!
When quoting starts getting that complicated I'd use a here-document and avoid quoting entirely. You can feed entire unmodified shell statement blocks into ssh raw that way, with no special quoting or escaping needed.

ssh-keysign
SSH-KEYSIGN(8) BSD System Manager's Manual SSH-KEYSIGN(8)NAME
ssh-keysign -- ssh helper program for host-based authentication
SYNOPSIS
ssh-keysign
DESCRIPTION
ssh-keysign is used by ssh(1) to access the local host keys and generate the digital signature required during host-based authentication with
SSH protocol version 2.
ssh-keysign is disabled by default and can only be enabled in the global client configuration file /etc/ssh/ssh_config by setting
EnableSSHKeysign to ``yes''.
ssh-keysign is not intended to be invoked by the user, but from ssh(1). See ssh(1) and sshd(8) for more information about host-based authen-
tication.
FILES
/etc/ssh/ssh_config
Controls whether ssh-keysign is enabled.
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_ecdsa_key
/etc/ssh/ssh_host_rsa_key
These files contain the private parts of the host keys used to generate the digital signature. They should be owned by root, read-
able only by root, and not accessible to others. Since they are readable only by root, ssh-keysign must be set-uid root if host-
based authentication is used. Note that ssh-keysign is not set-uid by default on Mac OS X.
/etc/ssh/ssh_host_dsa_key-cert.pub
/etc/ssh/ssh_host_ecdsa_key-cert.pub
/etc/ssh/ssh_host_rsa_key-cert.pub
If these files exist they are assumed to contain public certificate information corresponding with the private keys above.
SEE ALSO ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)HISTORY
ssh-keysign first appeared in OpenBSD 3.2.
