This is something I usually do:-
$NUTCH_HOME/bin/nutch mergesegs crawl/MERGEDsegments crawl/segments/*
rm -rf crawl/segments/*
mv crawl/MERGEDsegments/* crawl/segments
You might want to replace the second statement with a 'mv' statement
to backup the segments.

Hi all,
After recrawl several times, I have problem with the directory: merge-output. I
have digged into mail archive and found some clue: you should use a new dir
name for the new merge, e.g., merge-output_new, then mv merge-output_new to
merge-output.
Anyone can show me exactly how to do this ?
Thanks a lot
