Find The PID-Port In UNIX Without lsof

#P (PID con Port)
# v1.07 20/05/2008 sam@unix.ms
#
# If you have a Solaris 8, 9 or 10 box and you can't
# install lsof, try this. It maps PIDS to ports and vice versa.
# It also shows you which peers are connected on which port.
# Wildcards are accepted for -p and -P options.
#
# The script borrows Eric Steed's excellent "getport.sh" script.
