Making it an external command is fine; the speed difference is going to
be negligible in comparison to the pipeline of external commands you're
launching.
If you want to use .mkshrc, best use a shell function instead of an
alias. It avoids the shell-grammatical snags you get when you create an
alias out of a compound command. So add this to .mkshrc:
function using {
netstat -lantp | grep -i stab | awk -F/ '{print $2 $3}' | sort | uniq
}
