We already did. The BEGIN block, running before everything else, sets the field separator as =. Then the expression tells AWK to print all lines where the first field, $1, matches the given regex.

You could, kind of, sort of use grep, depending on if your system has egrep for all the bits and pieces that made solving the problem in awk easy; but even if you have extended support, it would be more awkward since it doesn't have columns like awk does. Why not use a tool that has all the right things available by default and is much simpler to use?

tcp-env

tcp-env(1)                                                    General Commands Manual                                                   tcp-env(1)

NAME

       tcp-env - set up TCP-related environment variables

SYNOPSIS

       tcp-env [ -rR ] [ -ttimeout ] program [ arg ...  ]

DESCRIPTION

       The  input  for  tcp-env  must be a TCP connection.  tcp-env finds out information about that connection, puts the information into several
       environment variables as described in tcp-environ(5), and runs program with the given arguments.

       Usually tcp-env is run from inetd.  It might instead be run from another server that already sets up the right  environment  variables;  if
       PROTO  is  set  to  TCP  when  tcp-env  is invoked, tcp-env assumes that all the other variables are set up properly, and it does not check
       whether the input is a TCP connection.

OPTIONS

       -r     (Default.)  Attempt to obtain TCPREMOTEINFO from the remote host.

       -R     Do not attempt to obtain TCPREMOTEINFO from the remote host.

       -ttimeout
              Give up on the TCPREMOTEINFO connection attempt after timeout seconds.  Default: 30.

SEE ALSO

       tcp-environ(5), inetd(8)

                                                                                                                                        tcp-env(1)
