# 43  
Old 02-02-2011
The corrections I proposed in post #33 were the correct syntax for redirecting the error channel.
Unfortunately the alternative suggestion in post #35 has been applied to the script and the redirection of the error channel is incorrect and is affecting the way the script behaves.
It's all about where the "2>/dev/null" is on the line. It needs to immediately follow the command (in this case "ls").

Quote:
if [ $((ls $i.* | wc -l) 2>/dev/null) -gt 1 ]
filename=$((ls $i.*) 2>/dev/null)
filename2=$((ls *Fe.ok | tail -1) 2>/dev/null)
Also there are too many brackets. We should be evaluating $(command) not the arithmetic syntax $((command)) .
Code:
if [ $(ls $i.* 2>/dev/null| wc -l) -gt 1 ]
filename=$(ls $i.* 2>/dev/null)
filename2=$(ls *Fe.ok 2>/dev/null| tail -1)

news::article::nocem

NoCeM(3pm)						User Contributed Perl Documentation						NoCeM(3pm)

NAME

       News::Article::NoCeM - a module to generate accurate nocem notices

SYNOPSIS

	 use News::Article::NoCeM;
	 my $nocem = new News::Article::NoCeM();

	 $nocem->hide($type, $spam);
	 $nocem->make_notice($type, $name, $issuer, $group, $prefix);
	 $nocem->sign($keyid, $passphrase);
	 $nocem->issue($conn, $ihave);

DESCRIPTION

       Creates a nocem notice on the Usenet articles, which may be posted normally to hide the messages.

USAGE

       use News::Article::NoCeM;

       News::Article::NoCeM is class that inherits News::Article and adds four new functions: hide(), make_notice(), sign() and issue(), redefine
       to disable two functions: post() and ihave().

   Article Methods
       hide ( TYPE, ARTICLE, [ARTICLE, ...] )
	   Hide one or more articles in the given "TYPE".  "ARTICLE" is an News::Article object that going to be hid. hide() will skip the
	   articles without Newsgroup or Message-ID and skip the ones already hid.

	   hide() returns the number of the articles hid.

       post
       ihave
	   post() and ihave() is disabled in News::Article::NoCeM.  Please use issue() instead.

       make_notice ( TYPE, NAME, GROUP, ISSUER, [ PREFIX ] )
	   Retrive articles marked by hide with "TYPE", and make a notice fot them. If there's only one type within a container, then the
	   container itself can be a notice. "NAME" is the identifier of the issuer. "GROUP" is the newsgroup the you will post nocem notice to.
	   "ISSUER" is the email address of the issuer. "PREFIX" is the announcement before the nocem notice, which may explain the criteria of
	   this notice, or where to find your public key for PGP verification.

	   make_notice() returns a News::Article::NoCeM object if success, and return undef if no article is hid.

       sign ( KEYID, PASSPHRASE )
	   Sign the content of the nocem notice with "KEYID" and "PASSPHRASE".	Please make sure that the issuer's public/secret keyring is ready.

	   sign() returns a News::Article::NoCeM object if success, and return undef if no article is hid, or pgp_sign failed.

       issue ( [ CONN, IHAVE ] )
	   Take optional "CONN" as a Net::NNTP object and issue the nocem notice.  "IHAVE" indicates that call Net::NNTP::ihave() for submitting
	   the notice, otherwise issue() will call News::Article::post() by default.

	   issue() return the result of News::Article::post() or issue().

NOTES

       Standard article manipulation information can be read in the News::Article manpages.
