       nngrab - news retrieval by keyword (nn)

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

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

       Keyword  case  is  ignored unless -cc is specified, and the
       _k_e_y_w_o_r_d 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.

NNOOTTEESS
       _n_n_g_r_a_b _c_a_n _b_e much  faster  than  the  equivalent  command
       shown  above, if the tertiary news subject database gener-
       ated by the _n_n_s_p_e_w(8) daemon exists.  To enable the faster
       operation, _n_n_s_p_e_w must be executed regularly by cron.

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

       _n_n_g_r_a_b  will  use  a  subject database generated by _n_n_s_p_e_w
       independent of its age.  Thus, if you stop running _n_n_s_p_e_w,
       remember to remove the subjects file as well.

BBUUGGSS
       Under  version 6.4, search of the "Keywords:" field is not
       supported.
       Search on name is not possible either.
