PROGRAM:

NAME

sm - Command-line interface to the INN storage manager

SYNOPSIS

sm [-cdHiqRrSs] [token ...]

DESCRIPTION

The INN storage manager is the subsystem that stores and keeps track of all of the
articles and what storage backend they're in. All stored articles are assigned a storage
API token. sm is a command-line interface to that storage manager, primarily used to
retrieve articles by those tokens but also to perform other operations on the storage
subsystem.

token is the token of an article (the same thing that's returned by grephistory or stored
in the history file). It looks something like:

@0502000005A4000000010000000000000000@

Any number of tokens can be given on the command-line for any function other than -s. If
none are, sm normally reads tokens from standard input, one per line. The default
operation is to retrieve and write to standard output the corresponding article for each
token given.

If -s is given, sm instead stores the article given on standard input (in native format,
not wire format) using the standard rules of the storage subsystem. If the article is
stored successfully, the token of the article is printed to standard output. Please note
that this does not make any attempt to write a history entry or any overview data, and is
therefore only useful under very specific circumstances.

OPTIONS

-c Show a clear, decoded form of the storage API token. Each part of the token is
explained, in a human-readable string. Amongst other elements, this command gives the
path to where the corresponding article is supposed to be stored.

-d, -r
Rather than retrieving the specified article, remove the article. This will delete
the article out of the news spool and it will not subsequently be retrievable by any
part of INN. It's equivalent to "ctlinnd cancel" except it takes a storage API token
instead of a message-ID.

-H Retrieve only the headers of the article rather than the entire article. This option
cannot be used with -d, -r, -i, or -S.

-i Show the newsgroup name and article number associated with the token rather than the
article itself. Note that for crossposted articles, only the first newsgroup and
article number to which the article is associated will be returned.

-q Suppress all error messages except usage errors.

-R Display the raw article. This means that line endings won't be converted to native
line endings and will be left as CRLF sequences; leading periods will still be escaped
for sending over NNTP, and the article will end in a CRLF.CRLF sequence.

-S Write the article to standard output in the format used by rnews spool files.
Multiple articles can be written in this format, and the resulting output can be fed
to rnews (on another system, for example) to inject those articles into INN. This
option cannot be used with -d, -r, -H, -i, or -R.

-s Store the article given on standard input using the normal storage rules for articles
as configured in storage.conf(5). Print the new token for the message to standard
output if it is stored successfully. If this option is given, no other options except
possibly -q should be given.

EXIT STATUS

If all operations were successful, sm exits with status 0. If an operation on any of the
provided tokens fails, sm will exit with status 1, even if the operations on other tokens
were successful. In other words, if twenty tokens are fed to "sm -r" on stdin, 19
articles were successfully removed, but the sixth article couldn't be found, sm will still
exit with status 1.

This means that if you need to be sure whether a particular operation succeeded, you
should run sm on one token at a time.
