[Statcvs-users] RE: question on generation

[David S G. <Dav...@la...>]

Aaron,

It sounds like what you really want is the 'cvs annotate' feature.  This cvs
command prints out the revision number and last editor for each line of each
file in your working CVS directory.  If you check out an older revision of a
file, you will see the 'history' of that file's lines up to only the version
you have checked out.

I don't know how statcvs does the line (was curious myself) counting, but
`cvs annotate | grep -c "username"` does a good job of counting lines of a
file last edited by 'username'.  If you add a pipe in there before the grep
with a `grep ';'`, you'd probably get a reasonable estimate of lines of
actual code.
