That's good! I've got to remember that one. We sometimes call it

You have read perlmod? Programming Perl has some stuff on modules
as well. I haven't actually written any modules but would think
perlmod should cover the basics.

Hi,
I use perl on Linux RH.
The problem is that i have 4 (four) perl executables. And i don't know
which on is used .
Here is the ouput of "ls -l /usr/lib/perl5" :
drwxr-xr-x 29 root root 4096 Sep 25 03:30 5.00503/
drwxr-xr-x 31 root root 4096 Sep 13 12:19 5.6.0/
drwxr-xr-x 3 root root 4096 Oct 9 2000 man/
drwxr-xr-x 5 root root 4096 May 8 2000 site_perl/
I know that i have perl5.6.1 under "/usr/local/lib/perl5". I am confused of
too many .... executables.
I want to user Amavis, when it's launched it try to locate modules under
those directories :
/usr/lib/perl5/5.6.0/i386-linux

Try the command "which perl". That should indicate which one "perl"
refers to. Probably the most recent executable is under the 5.6.0
directory listed above. You could also do "ls -l /usr/bin/perl" to see
what that is linked to.

You can put the line: use lib '/usr/local/lib/perl5'; at the beginning
of your perl script.
(One remark: it may be that /usr/local/lib/perl5
is linked to one of the directories you listed above. You could try
ls -l /usr/local/lib to see if the perl5 directory is linked to one
of the above.)

I just upgraded to 5.6.1 and the problem vanished here. So I'm not sure if
the bug isnt partially fixed already. On the other side, you were able to

The mail must come from the "usual" SMTP server (i.e. the one used by
the usual mail program when mail is sent from the machine in
question). The problem is, I can't figure out what this server's
name/domain is. Is there a program that will reveal that information?

The set of requirements seemed intriguing enough to take a look at
mutt. It appears that the www.mutt.org web site is alive and
kicking with lots of great info about using and customizing it.
I'm not really in a position to tell you what you need to do to
achieve your goals (I'm an MH user) but it appears that the information
is in the mutt docs to get most of what you want with a few minor config
changes.
Good Luck
BTW if you like lynx you might just take a quick look at w3m.

I'd recommend abandoning the flat coding style and make use of the LWP
module available on CPAN. This is a tried and true way to bypass the
complexities of the HTTP protocol and get down to doing the task at hand.
Among other things the lwpcook manual page includes the following:
COOKIES
Some sites like to play games with cookies. By default
LWP ignores cookies provided by the servers it visits.
LWP will collect cookies and respond to cookie requests if
you set up a cookie jar.
use LWP::UserAgent;
use HTTP::Cookies;
$ua = LWP::UserAgent->new;
$ua->cookie_jar(HTTP::Cookies->new(file => "lwpcookies.txt",
autosave => 1));
# and then send requests just as you used to do
$res = $ua->request(HTTP::Request->new(GET => "http://www.yahoo.no"));
print $res->status_line, "\n";
As you visit sites that send you cookies to keep, then the
file lwpcookies.txt" will grow.

I meant that there is no 'Open With' in the right click menu so that
I could override opening with perl for those times I want to edit the

i use Vim for just about everything on NT, so i always have this
registry key set:
REGEDIT4
[HKEY_CLASSES_ROOT\*\shell\Vim it\command]
@="vim_binary_directory\\gvim.exe \"%1\""
this allows me to Vim everything, whether is associated or not.

There are three shell tool converters for perl a2p translates awk into perl,
s2p translates sed to perl and find2perl translates a find command line
into a perl script. But to my knowledge there is no general tool for
converting a shell scripting language into an equivalent perl program.
The perl FAQ contains the following advice:
How can I convert my shell script to perl?
Learn Perl and rewrite it. Seriously, there's no simple
converter. Things that are awkward to do in the shell are
easy to do in Perl, and this very awkwardness is what
would make a shell->perl converter nigh-on impossible to
write. By rewriting it, you'll think about what you're
really trying to do, and hopefully will escape the shell's
pipeline datastream paradigm, which while convenient for
some matters, causes many inefficiencies.
Good Luck

The place you look for Perl modules is CPAN - www.cpan.org (but try to
find a mirror near you under 'CPAN sites map'). On the CPAN main page,
there is a heading 'Searching', and under this are several links to sites
that allow you to search for modules. If you tell a search engine to
look for 'Excel', you should get a list of modules relating to Excel.
If you have the CPAN module configured, doing `perl -MCPAN -e shell`,
then asking it 'm /Excel/' will also generate such a list (if you
don't have it configured, then running it with the above incantation
for the first time will walk you through configuring it).
If you are using ActiveState perl, you might want to investigate using
the ppm utility to search for modules. I don't use this, so I can't
advise - I suggest ActiveState's website or the included documentation.
HTH,
Cheers,
Damian

gzip is meant to act on single files, not on groups. You can use zip
or tar to group files. The CPAN provides some modules to do this
without the help of external programs:
Archive::Tar
Archive::Zip (requires Compress::Zlib)
Archive::Any

I have not seen any of the kind.
For most protected environments, the usual approach is to write a
small device driver for the kernel, and then use that in userspace.
Are you certain that your device is unsupported by Linux?

I'd bet that nicely-optomized C programs could give Fortran programs a

For some reason computer scientists who have a lot of number crunching
to do, choose to do so in Fortran. I do not know why, but I think
they know what they are doing.
Perhaps it is less difficult to parallize on multi-CPU machines?
But that is irrelevant to us here. We sacrifice speed and efficiency
for comfortable and unreadable programs.

You'd bet that, but you'd be wrong. :)
Fortran, generally lacking in pointers, has far less uncertainty about it,
which makes it much, *much* easier to optimize. If you write to its
problem domain, nothing'll touch Fortran for speed.

The following prints modification date of the page in epoch seconds.
perl -MLWP::Simple -le '@s = head("http://www.cpan.org")and print $s[2]'
Maybe a version of this could be useful to the OP?

shouldn't that be $quotient :)

if you want the remainder, you can use the modulus
operator:
$remainder = $number1 % $number2;

If it is more like an IRC client, then maybe you should have a look at
select() in the perlfunc documentation, or probably better, the
IO::Select module that comes with Perl.
Alternatively, you could have a look at an Event-style of programming.
Have a look at the Event modules (available from CPAN), or maybe you
can look through the archives on this group for posts by Uri Guttman
for more guidance on this.

I think it is probably a wise move, especially if you don't know much
about thread programming already.

If you post a bit more about how exactly this client is supposed to
work, and what is going in and out, maybe we can guide you a bit more
towards the solution that is most likely to work well...

Really? I'm sure I've been bitten under Perl 5.6.1 by exactly this: I
don't remember the exact code (it's at work - I'm sure I could dig it
out
if anyone were interested) but ISTR I was using foreach to alias a
reference to part of a complex data structure - along the lines of
my $thing = $_ =~ /something/ ? $_ : "Stuff$_" for
$ridiculously_long_expr;
I was surprised to find $thing undefined until I rewrote as
my $thing;
$thing = $_ =~ # and so on as above.........
and I assumed that the for.. modifier had caused the my.. declaration to
be
scoped to that single line. I'll try it again tomorrow in case I'm
misremembering.

Calm. Yes, it's the => that enables auto-quotes. Sorry about that.
my $therm = $mw->Thermometer(
-label => 'Reactants Temp',
-tscale => 'Celsius',
)->pack;
And yes, it does make the option distinct from its value.

Many modules for ActivePerl are available through the included PPM
utility - a listing is at http://www.activestate.com/ppmpackages/.
However, if one you want isn't there, you'll need nmake to use
CPAN.pm; this is available from
ftp://ftp.microsoft.com/Softlib/MSLFILES/nmake15.exe
Win32 ports of Unix tools are available from
http://www.cygnus.com/misc/gnu-win32/
http://www.itribe.net/virtunix
Also, Win32 tar and gzip programs are available at
ftp://gatekeeper.dec.com/pub/GNU/
in the appropriate directories. Once you install these
in your PATH, reconfigure CPAN.pm and it will pick them
up and use them.
