nngrab
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 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 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.
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 supported.
Search on name is not possible either.
