NAME
       nngrab -	news retrieval by keyword (nn)

SYNOPSIS
       nngrab [	-c ] keyword

DESCRIPTION
       nngrab  invokes	nn  on	all USENET articles whose subject (or keyword)
       field(s)	contain	an instance of keyword.	 nngrab	is a  fast  equivalent
       for:
	    nn -mxX -s/keyword all

       For example,
	    nngrab tesla
       will retrieve items concerning Nikola Tesla.

       Keyword	case is	ignored	unless -c is specified,	and the	keyword	can be
       a regular expressions (escaped to avoid conflicts with the shell).  For
       example,
	    nngrab "n.*tesla"

       The  range  of  search includes all newsgroups on the system, including
       ones which are unsubscribed.

FILES
       $db/subjects   subject database

SEE ALSO
       nn(1), nnspew(8), egrep(1)

NOTES
       nngrab can be much faster than the equivalent command shown  above,  if
       the  tertiary  news  subject database generated by the nnspew(8)	daemon
       exists.	To enable the faster operation,	nnspew must be executed	 regu-
       larly by	cron.

       nngrab  uses  egrep(1)  to scan the subject database, so	if you are not
       running fast egrep (GNU-style) this is all for naught.

       nngrab will use a subject database generated by nnspew  independent  of
       its age.	 Thus, if you stop running nnspew, remember to remove the sub-
       jects file as well.

BUGS
       Under version 6.4 onwards, search of the	"Keywords:" field is not  sup-
       ported.
       Search on name is not possible either.
