Subject: [Q]CGI script to simulate a form submition?
Message-Id: <6jbtc2$nar$1@nuscc.nus.edu.sg>
hi all,
Is there any way to use a CGI script to simulate a form submition? Let's
say there is a form (POST) located at http://www.nus.edu.sg/form.html
which actually calls the cgi script /cgi-bin/script.cgi. Inside the
form, let's say there are two fields, "Age" and "Name". So now is there
any way to run the script.cgi just as if it were started by the "submit"
request sent from a browser client?
Please follow up or sent your email to ccegongw@leonis.nus.edu.sg. Thanks!
Regards

It's convention started and suggested by Lars. Just like you won't find
the de facto signature separator "\n-- \n" anywhere from the RFCs.
This snipped is from Procmail Tips page at:
ftp://cs.uta.fi/pub/ssjaaa/pm-tips.html
jari
30.6 Mail-Copies-To header
[Suggested by Lars, the Author of Emacs Gnus]
...Mail-Copies-To: is a header line used in messages on
Usenet to direct copies by email of followups to posts.
http://www.math.fu-berlin.de/~guckes/rfc/mail-copies-to.html
[SL Baur <steve@xemacs.org>] The `Mail-Copies-To:' header should
control how your email (and Usenet) client prepares a followup
message. It gives control to the sender of a message whether
`courtesy' duplicate copies of messages should be sent.
There are two forms:
Mail-Copies-To: never
Do not automatically include the sender of the message being
responded to. There are two canonical examples.
Usenet:
From: foo@foo.bar
Newsgroups: comp.emacs.xemacs
Mail-Copies-To: never
A followup in a conforming client should generate in the response
message headers:
Newsgroups: comp.emacs.xemacs
Email:
From: foo@foo.bar
To: mailing-list@somewhere.com
Cc: luser@somewhereelse.com
Mail-Copies-To: never
A followup in a conforming client should generate in the response
message headers:
To: mailing-list@somewhere.com
Cc: luser@somewhereelse.com
The second form includes a properly formed RFC822 email address as
the parameter:
Mail-Copies-To: someaddress@somewhere.com
In this case, the sender of the message is specifically requesting
that responses to the message not only go to the main forum (either
mailing list or Usenet newsgroup), but a duplicate copy should also
be sent to `someaddress@somewhere.com'. There are (again) two
canonical examples.
Usenet:
From: foo@foo.bar
Newsgroups: comp.emacs.xemacs
Mail-Copies-To: foo@foo.bar
A followup in a conforming client should generate in the response
message headers:
Newsgroups: comp.emacs.xemacs
Cc: foo@foo.bar[1]
Email:
From: foo@foo.bar
To: mailing-list@somewhere.com
Cc: luser@somewhereelse.com
Mail-Copies-To: foo@foo.bar
A followup in a conforming client should generate in the response
message headers:
To: mailing-list@somewhere.com
Cc: luser@somewhereelse.com, foo@foo.bar[2]
There is no requirement that the address in
`Mail-Copies-To' match the `From' address. Footnotes: [1] Or `To:
foo@foo.bar' [2] It is also acceptable to put `foo@foo.bar' in the
To: line.

Ilya, why exaggerate? It helps you not. The examples I give there
require knowing grep and either zsh or find+xargs, so the tool counts
are either two or three, never four.
Besides, if your man system works, then you just "man -k" and it's
easy. The zsh approach, or the find+xargs approach, is needed only if
your system has a really stupid "man" command installed.
The key here is that text files can be searched with whatever tool(s)
you find convenient and appropriate. "Book" files (or other formats)
can be accessed only with special-purpose tools like VIEW.EXE. I know
which I'd prefer to have around.

No, it's not.
Firstly, you've no real guarrentee that some arbitrary subroutine
doesn't fork something off itself (I have a few which parse the output
of UNIX commands to get particular pieces of information, for example).
Secondly, there's no guarrentee that your script wasn't exec()ed by some
previous process which itself has made children - naturally these remain
children of the exec()ee.
Use waitpid instead. If you must use wait (and often it's desired, if for
example you've forked a few children and want to wait for whichever completes
first), then keep track of all your pids, and ignore the others.

It's a shame that so many people feel obliged to use spam resistant
return addresses otherwise it might be feasible to provide the group

How about an a-moderator which allocates a newbie score to each post and
then changes the subject to steer all posts which fall below some

The following test makes *me* think it is:
#!/usr/local/bin/perl -w
my $a;
if ($a = "something") { print $a }
__END__
This is perl, version 5.004_03
Either you didn't test this before posting, or you forgot the -w flag.
Or should I upgrade my perl? (Frequent Answer to Questions)

use LWP::UserAgent in conjunction with HTTP::Request.
It will return remote documents and headers.

Can't you just extend this?
if ($function eq '+') {
return $a + $b + $c;
} elsif ($function eq '*') {
return $a * $b * $c;
}
# case not provided! error
This way, if $function isn't in the list you provided, it will fall
through, and you can report an error. The advantage is: YOU are in
control.

From: Christopher Berg <chriz@space.eu.org>
Subject: POSIX ????
Message-Id: <3559517D.2A11CEFA@space.eu.org>
When using Active Ware4s Perl distribution I had the POSIX library on my
machine that is I downloaded it and installed it ....
I wanted to use the generated unique strings for passwords or temp file
names etc.
Since ActiveWare4s version of Perl I have changed to this much better
version eh(!) the Real Perl distribution the native one...
When using this distribution Ill get all modules already included in the
package thats great .... BUT POSIX has either left the building or wasnt
good enough to be included or could it be that POSIX has an replacement
in the Native version of Perl?
Could anyone please help me out here ... I have searched on CPAN sites
and just found a link to this strange named guy (I think its short for
his name or something) and he has a POSIX catalog but inside of that
catalog its just alot of strange modules that I - sorry to say - doesnt
have a clue what they are ?
Or should I write a new POSIX kinda type library for just generating
unique strings? I still think that there must be a solution for this out
there somewhere.
So please if anyone out there has the Native Perl distribution and have
solved this with unique temp filenames and/or passwords please let me
know ,ok?
regards

Ah, that would explain why it worked for me under the latest Perl. I will
admit that, now that it's been pointed out to me, I'll probably lean
toward the interpolation-into-format-string technique instead. It looks a
bit cleaner, obviously ports to recent Perl versions better, and just
feels more Perlish to me.

Yes, that's why I liked the sprintf version better. Larry Rossler was
kind enough to point out that the precision-indirection trick is better
handled by interpolating into the format string in Perl. Just goes to
show the power of old habits...when I start doing numerical code, I also
shift gears into C-think. :)

It's actually impossible to say how many either has a priori, though the
latter does more strongly suggest 4. Abigail's correct in pointing out
that only exponential notation is unambiguous.

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
