Add all KDE crap to slackpkg blacklist

First, we will backup our blacklist file:
cp /etc/slackpkg/blacklist /etc/slackpkg/blacklist.old

Mount your slackware install dvd/cd/usb

Navigate to the slackware directory on the install media (you need to be inside the directory that has all the package sets a, ap, d, e, n... etc...)

Then, as root issue this command:

\ls kde | grep '\.t.z$' | rev | cut -d- -f4- | rev >> /etc/slackpkg/blacklist

note the '\' it is *NOT* a type-o!  this will add all the packages inside the kde directory to the bottom of your blacklist file.
