NNGRAB(1) General Commands Manual NNGRAB(1) 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 exam- ple, 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 regularly by cron. nngrab uses egrep(1) to scan the subject database, so if you are not run- ning 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 subjects 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. AUTHOR James A. Woods, NASA Ames Research Center E-mail: jaw@ames.arc.nasa.gov 4th Berkeley Distribution Release 6.6 NNGRAB(1)
