How to search cvs comment history

Question

I am aware of this command: cvs log -N -w<userid> -d"1 day ago"

Unfortunately this generates a formatted report with lots of newlines in it, such that the file-path, the file-version, and the comment-text are all on separate lines. Therefore it is difficult to scan it for all occurrences of comment text, (eg, grep), and correlate the matches to file/version.

(Note that the log output would be perfectly acceptable, if only cvs could perform the filtering natively.)

EDIT: Sample output. A block of text like this is reported for each repository file:

RCS file: /data/cvs/dps/build.xml,v
Working file: build.xml
head: 1.49
branch:

access list:

Answer 1

The -w options seems to work better with the -S option. Otherwise there are additional results which don't seem related to the userid. Perhaps someone can explain it.

cvs log -N -S -w<userid> -d"1 day ago"

With that I have been getting reasonable success piping it to grep:

cvs log -N -S -w<userid> -d"1 day ago" | grep -B14 "some text" > afile

I'm redirecting output to a file since the cvs log is noisy and I'm not sure how to make it quiet. I suppose an alternative is to redirect the stderr to /dev/null.
