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.
