SYNOPSIS
snscan [options] articlespec...sncat [options] articlespec...
sncancel [options] articlespec...
options: [-n] [-s since] [-o outputfile]
DESCRIPTION
- snscan
-
displays information on all articles specified by
articlespec,
in the form
newsgroup serial id
on a line, one line per article matched. This output is suitable for feeding to snprimedb. - sncat
- displays the articles specified by articlespec.
- sncancel
-
marks articles specified by
articlespec
as canceled, so they become unavailable to
sn
programs.
ARGUMENTS
articlespec defines a broad pattern for articles. It takes two mutually exclusive forms.- Specify by newsgroup and serial number
-
Here
articlespec
is
newsgroup[:range[,range]...]
where each range is
serial[-[toserial]]
(where toserial is greater than serial). If toserial is omitted, then all articles after serial are matched. If both serial and toserial are empty, then only the first and last articles are matched. - Specify by articles message ID
-
Here
articlespec is
-i
id...
where each id is a message ID, angle brackets optional.
OPTIONS
- -n
-
This option weeds out articles that are aliases.
If an article is crossposted,
there will be an original copy, the others will be aliases to it.
This option prevents information being displayed if it is not from
the original copy.
- -ssince
-
This option weeds out articles that were obtained before
since.
since
is in the format
year/month/day[:hour:minute]
where each is a number.
year
may be 2 or 4 digits, and
/
and
:
can be any non-digit character.
- -ooutputfile
-
Write output to
outputfile
instead of descriptor 1. Sometimes you just don't feel like using
the shell.
