pkg_info output?

[David Armour]

hello,

I just used the following log-on tip to produce the list of duplicate 
pkg/ports installations below. 

pkg_info | sort | sed -e 's/-[0-9].*$//' | uniq -c | grep -v '^[[:space:]]*1' 

   3 autoconf
   3 automake
   6 docbook
   2 gcc
   2 glib
   2 gtk
   2 libtool
   2 perl
   2 xorg-fonts

I have also just gawked my way (pun intended) through the sed manpage, but I'm 
no programmer: I don't know what the output means. Warnings, translations, 
hints, appreciated.
