cvshistoryfilter.hlp by RJL 94/6/10

This file includes the approximate  commands which I used to extract 94sbde history 
from cvs and sort it by filename and date.  (They are not exact - 
I fixed some field alignment problems and lost some intermediate steps.)
To get the initial report, I ran (approximately):

	cvs -d CVSROOT history -a > ~/bde8/cvshistory.10jun94 

which produced a large (83K byte) file, sorted by username,
of all commit  (Add and Modify) actions on 94sbde's CVS files.

I wanted a sort by filename and date. Sort is very tricky 
and I couldn't get it to sort by field 6 then field 2 (filename and date). 
So I used awk first to reformat the columns to simplify sorting:
The printf statement aligns the columns vertically for readability.

awk '{printf("%-26s %1s %-5s %s %s %-8s %21s%s%s \n", 
	$6,$1,$5,$2,$3,$4,$7,$8,$9)}' 	< ~/bde8/cvshistorymods.10jun94 
					> ~/bde8/cvshistoryawk.10jun94
I may have used  %s instead of %21s%s%s above.)

Then I sorted this  file with the entire record as sort key:
	sort ~/bde8/cvshistorysort.10jun94 > ~/bde8/cvshistorysort.11jun94

Then I used awk again to separate files by a blank line:

 	awk '{if ($1!=oldname) print "";oldname=$1;print $0}'
					< ~/bde8/cvshistorysort.10jun94
					> 94sbdehistory.10jun94
(I actually used print "\n" which inserted two lines 
since I could not get 'print "";' to work above.)

I moved the result to /usr/proj3/case/94s523/94sbde/bde_rev_history.10jun94.
