Hello, Gordon.
I've got a script that compares the packages installed on two different

Hello, Gordon.
Sorry, I just noticed that the script I posted has comments and usage
info relating to an older script I wrote called "dpkg-diff", which
compares the output of "dpkg -l" more like Alan suggested. This level of
detail is less useful in most circumstances, because you normally want
to know what packages are installed regardless of their version. There
are, of course, circumstances where you do want to compare versions and
that's why I wrote "dpkg-diff".
Attached is a corrected version of my "dpkg-dsel" script, and my older
"dpkg-diff" script that it is based on.
Bye,
Tony.
