perl -e "print for grep ! /up to date/, `ppm upgrade`" > update.txt

    Thanks tye. I should have re-read perlop, since it is so seldom that I use the qx// (and backticks) operators.

    While we're at it, print prints lists too. ;)

    perl -e "print grep ! /up to date/, `ppm upgrade`" > update.txt
