Gary,
just remove the leading $ character before the sysctl command. The $ in the
command line that you copied is the console prompt, not part of the command.
But $ is also used to represent variables in Unix, so $sysctl assumes a
completely different meaning. Because the $sysctl variable doesn't exist, it is
translated into an empty string and skipped. The next thing in line would then
be "-A", that would be treated as if it was a command, a non-existent command
for that matter, hence the "-A: command not found" error message.
