NAMEnngrab - news retrieval by keyword (nn)
SYNOPSISnngrab [ -c ] keyword
DESCRIPTIONnngrab 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
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,
FILES$db/subjects subject database
SEE ALSOnn(1), nnspew(8), egrep(1)
NOTESnngrab 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 running fast egrep (GNU-style) this is all for naught.
BUGSUnder version 6.4 onwards, search of the "Keywords:" field is not supported.
Search on name is not possible either.
