Ah, so setting RS="" makes awk break records apart on blank lines. So you can just read in records one by one and sort them. Nice!

newgrp(1)						      General Commands Manual							 newgrp(1)

NAME
newgrp - change effective group ID sg - execute command with different group ID SYNOPSIS
newgrp [-l] [group] sg group -c command DESCRIPTION
The newgrp command changes the user's real and effetive group ID by replacing the current shell with a new shell. A new shell is launched even if an error occours. A password is requested if the group has a password and the user is not listed in the group file as being a member of that group. The pass- word can be changed with the gpasswd(1) command. If the new effective group ID is not in the supplementary group list, newgrp will add the new group ID to the supplementary list, too. With no operands and options, newgrp changes the user's group IDs (real and effective) back to the group specified in password and group file. The sg command works like the newgrp command, except that it executes the given command with /bin/sh and upon exit the group ID of the cur- rent shell is not changed. OPTIONS
-l, --login reinitialize the environment as if the user logged in. --help Print a help list. -u, --usage Print a short usage message. -v, --version Print program version. SEE ALSO
gpasswd(1), group(5), passwd(1), passwd(5), su(1) AUTHOR
