cat | grep | (sed|awk) lines have always bothered me to no end.  How
about, instead, one of the following function bodies:

    awk '/MemTotal/ { print $2}' /proc/meminfo
    sed -r -e '/MemTotal/!d' -e 's/[^0-9]*([0-9]+).*/\1/' /proc/meminfo
    perl -ne '/MemTotal:\s+(\d+)/ && print "$1\n"' /proc/meminfoo
    grep MemTotal | (read tag size units; echo $size)

Normally, I wouldn't bring it up, but there's *so* many ways to do that
better, it's sad.  Note that I could've listed many more, but that
would've been sad as well.  (Actually, even this much is somewhat sad.)
Personally, I'd vote for the first or third of this group.
