I suspect it is for an older style of history file. Here is a similar script that works for 2.11 history files. As with Geoff's script, replace \t with a tab (in two places) before running it. sed -e 's/[^\t]*\t *//' -e '/[a-z]/!d' -e '/cancelled/d' \ -e 's/ .*//' /usr/lib/news/history | uniq -c -- Joel Shprentz Phone: (703) 848-7305 BDM Corporation Uucp: seismo!bdmrrr!shprentz 7915 Jones Branch Drive shprentz@bdmrrr.bdm.com McLean, Virginia 22102
