0) pkg_info
list all packages installed
1) sort
sort the resulting list from 0) by package name
2) sed -e 's/-[0-9].*$//'
delete everything after a dash followed by a number
followed by everything else. so autoconf-2.59_2 becomes autoconf.
3) uniq -c
from the manpage:
-c Precede each output line with the count of the number of times
the line occurred in the input, followed by a single space.
so counts how often autoconf is in the list resulting from 2)
4) grep -v '^[[:space:]]*1'
delete every line starting (^) with one or more space characters " "
followed by 1 in the list resulting from 3)
this deletes lines where only 1 version exists, e.g.:
1 borg

so there are 3 versions of autoconf installed, 3 versions of
automake and so on.
the script is not quite correct because these two packages are
counted as two versions of xorg-fonts:
xorg-fonts-100dpi-6.8.2
xorg-fonts-75dpi-6.8.2
homework: find a version that works :-)
hth,
