ssh remote command



You put the thing in double-quotes, which means the $2 in the awk 
command will be replaced by the shell on server1 while it parses 
the line. If you haven't run "set" in your command shell, then the 
$2 will be replaced by a null string, which turns the awk command 
into 

    awk '{ print }'
