Re: Learning Perl book, Chapter 1 example: open MAIL, |mail email_address doesn't work

A mail client (aka a mail user agent or MUA) and an SMTP program (aka a mail transport agent or MTA). The 'mail' program is an MUA. It passes messages to a local MTA for delivery. IIRC on OS X the MTA (sendmail) is installed, but not configured, so 'mail' successfully hands the message over to sendmail, which then neither knows what to do with it, nor knows how to warn you of the fact. -- David Cantrell Beekeeping is like being a lion tamer, but with smaller lions, and more of them. -- arp

It's unfortunate that mail exits with 0, however. I was burned by this not very long ago (ran M-x mail in emacs for a quick mail, no error, never got there. Eventually I ran mailq and realized sendmail wasn't setup properly). It isn't mail's fault, though. sendmail returns with 0 as well. -Dan -- Dan Mills [EMAIL PROTECTED] All Minds!

I know that Richard is working two sets of questions: a. how do I do this specific thing from learning perl b. how do I do email with perl May I highly recommend http://search.cpan.org/author/MARKOV/MailTools-1.58/ as an alternative for doing the specifics of emailing from perl. Sorting out sendmail is better these days but can be more complex than merely learning perl. I have some illustrations of email tricks in perl up at http://www.wetware.com/drieux/pbl/Other/email/ which I did on my little OSX box. As for the learning perl part, if he understands that the code in the book was essentially demonstrating invoking an external command, eg: '/usr/bin/mail' from perl, then he has the basics for doing one of the basic 'popen()' style solutions. But as we notice, the book presumes that everyone understands MTA/MTU and that by default 'sendmail' is an available service on the local host. ciao drieux ---

Re: [MacOS X] consider useshrplib='false' by default

I had thought that the shared libperl provided by Apple was actually used by at least one other common application (and that not breaking that application was part of the background for Apple's original choice of installation location for their shared libperl). I've never used Mac OS X, so I don't have any firsthand knowledge either way. So I did (change #19681). Since useshrplib='false' is the default anyway, I suggest the following minor editorial change: diff -u perl-5.8.x/hints/darwin.sh perl-5.8.x-andy/hints/darwin.sh --- perl-5.8.x/hints/darwin.sh Wed Jun 4 02:40:33 2003 +++ perl-5.8.x-andy/hints/darwin.sh Wed Jun 4 11:18:23 2003 @@ -141,9 +141,7 @@ ldlibpthname='DYLD_LIBRARY_PATH'; # useshrplib=true results in much slower startup times. -case $useshrplib in -'') useshrplib='false' ;; -esac +# 'false' is the default value.
