/bin/sh and /bin/ksh on Solaris 2.8 and below (and perhaps 2.10+ but I
haven't checked yet).

As usual /usr/xpg4/bin/ksh works much better.

(This is one reason for the recommendation to set
SHELL=/usr/xpg4/bin/ksh before bootstrapping GCC on that platform: that
and its use of temporary files and fork() to implement here documents
and redirection around loops...)

>>> 		sed -rn -e '/^ID_VIDEO_(WIDTH|HEIGHT)/ {s/.*=//;N;s/\n.*=/x/p;h}' \
>>> 				-e '$ {g;s/^$/unknown size/;T;p}'

I've used sed as a grep replacement before, but *that* is, well, I
recommend you talk to Greg Ubben one of these days: you obviously think
in similar ways.
