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.
EXAMPLES¶
- sncancel linux.lemmings:12
- Cancel article 12 from linux.lemmings.
- snscan linux.lemmings:4,12-
- Display information on article 4, and also articles 12 to
the most recent article, from linux.lemmings.
- sncat -n -s 1998/4/1 linux.lemmings
- Display all articles that are not aliases, and which were
entered after April 1 1998, from linux.lemmings.
- snscan -i '123@myhost'
- Display information on the article whose ID is
<123@myhost>, in whichever newsgroup it is found.
FILES¶
Each
articlespec or
id on the command line refers to articles in
the news spool located in
/var/spool/sn.
ENVIRONMENT VARIABLES¶
- SNROOT
- If this is set and is not empty, the value is used in place
of /var/spool/sn, the default news spool directory.
EXIT CODES¶
snscan exits 0 on success, 1 on usage error, 2 on system error, and 3 on
other errors. It is not an error to specify an article that does not exist, or
which does not meet the
since criterion.
