Could you please look at it too?
Hi.

What's the error? And what's with all those asterisks? I was about to edit your post, fixing a couple of things along the way, to look more like this:
Code:
#!/bin/sh

# ???? $ cat mycp
#

# copy a file

#

if [ "$#" -ne 2 ]
then
  echo "Usage: mycp from to"
  exit 1
fi

from="$1"

to="$2"


#
# See if the destination file exists
#

if [ -e "$to" ]
then
  echo "$to already exists; overwrite (yes/no)?"
  read answer


  if [ "$answer" != yes ]
  then
    echo "Copy not performed"
    exit 0
  fi
fi


#
# Either destination doesn't exist or "yes" was typed
#

cp $from $to**** # proceed with the copy  # **** means?

but thought maybe I'd missed something!

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).

AUTHORS

     OpenSSH is a derivative of the original and free ssh 1.2.12 release by Tatu Ylonen.  Aaron Campbell, Bob Beck, Markus Friedl, Niels Provos,
     Theo de Raadt and Dug Song removed many bugs, re-added newer features and created OpenSSH.  Markus Friedl contributed the support for SSH
     protocol versions 1.5 and 2.0.  Jonathan Amery wrote this ssh-argv0 script and the associated documentation.
