NAME
nnspew - subject database manager (nn)
SYNOPSIS
nnspew
DESCRIPTION
nnspew builds a sorted database of all available subjects in the
nn article database for fast access via the nngrab utility.
nnspew should be activated regularly to rebuild the subject
database, e.g. by cron. For example:
2 6,9,12,15,18,21 * * * root /bin/nice /usr/lib/nn/nnspew
Cross posted articles are only represented in the database once, and
identical subjects in each group are merged into one to use a minimum
of disk space. This saves about 50% of the disk space otherwise
required.
FILES
$db/subjects subject database
SEE ALSO
nn(1), nngrab(1), egrep(1)
NOTES
nngrap will use the subject database generated by nnspew
independent of its age. Thus, if you stop running nnspew,
remember to remove the subjects file as well.
BUGS
nnmaster should automatically append new articles to the subject
database to keep it up-to-date, and thus require less frequent
rebuilding using nnspew.
