You could even do 16:28 $ psselect -p _1 xray.ps 21 /dev/null | tr [] \n\n | grep ^[0-9] 8 although I'm sure there's a more elegant way.

I think there are more than thousand solutions ;-)
grep ^%%Pages file.ps|awk '{ print $2 }'

grep ^%%Pages file.ps|awk '{ print $2 }'
any idea why this is 2x as fast as the equivalent
awk '/^%%Pages/ { print $2 }' file.ps
?

Because grep, being a compiled program, can do file I/O faster than
awk, which is interpreted.
