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.
