This reminds me: in the current WIN32 build (303), -d '/perl/' fails,
though -d '/perl' succeeds. This causes a failure in AutoSplit.pm
because in checking to see if it needs to build a new directory subtree,
it tests for a directory terminated with '/', doesn't find it and then
tries to create it, which fails because it already exists. Is this a
known bug?

You know, based on the volume of mail I've received on this, this might
be the one most single messed-up issue in server programming today. :-)
In fact, I was on IRC the other day when I mentioned this to someone,
and they said "HEY that's the problem with Rob Kolstad's *notes*".
Wow, so I've now fixed a piece of software that's been around for a
decade-and-a-half that I didn't even know was broken. :-)
Sometimes, you just gotta hit the nail on the head for a while...

Well, it's clear to me that someone did a non-portable thing. :-)
Lessee... typing "man date" in another window... (my favorite "man"
command... :-) Hmm. It pointed me at strftime(3c) for the best stuff.
OK... %D = %m/%d/%y which in turn is month[1-12]/day[1-31]/year[01-99].
Ugh. That's not year-2000 compliant. Bleh. And %r is am-pm time.
OK, so something like this would work:
{
my @now = localtime;
$date = sprintf "%d/%d/%02d %d:%02d%s\n",
$now[4]+1, $now[3], $now[5],
1+($now[2]+11)%12, $now[1], $now[2] > 11 ? "pm" : "am";
}
And that's how it should have been done in the first place, but
someone might have been too lazy to look up Perl's more-than-adequate
"localtime" function, but chose instead to fire off a separate process
for that.
Hope this helps.

I'm new to Perl and Regular Expressions and would appreciate any help with
the following:
I have a Eudura Email file which includes approximately 150 database
entries in it. Essentially in the following format:

I would like to create a regular expression to extract the name and email
addresses an put it in a pipe delimited format like this.
Julie Jackson|jacksj8@mail.place.edu
Michael Williams|Mic.Will@abc.com
...
What I have created so far gives me the following result.
|Julie Jackson
|jacks8@mail.place.edu

Using
#!/usr/bin/perl
open(MAILLIST, maillist);
while(<MAILLIST>) {

}
}
...
Thanks for any assistance.

To: Roy <boylesr@mail.mcm.edu>
Subject: Re: Hiding path name during download
Message-Id: <33294E05.4C4A@haywood.org>
The way that I do this is to do a download straight from my own cgi/pl
file. Return a header of the appropriate Content-type: (it can be html
or anything) and also include a Content-disposition: header specifing an
attachment (as opposed to inline) and then the suggested filename. After
the header send your data. Open the file and pump it out if its in a
physical file and not generated by the script.
When you return these headers the browser will bring up the save as
dialog box and use the suggested file name (without the path). It works
fine in Netscape but MS Explorer does not quite get the file name right
(no looked into it deeply though).
For all the details on the Content-disposition header read
http://ds.internic.net/rfc/rfc1806.txt
Here is an example of the header I use :
HTTP/1.0 200 OK
Content-type: text/txt
Content-disposition: attachment; filename="keys.txt"
Good luck,
Rodos

[....]
sub listString {
local(@l) = @_;
local($temp) = NULL;
foreach $i (0..4) {
$temp .= $l[$i];
}
$temp;
}
I have a subroutine as above. But the interpreter keeps
complaining that I use uninitalized value for $temp.
How can I avoid this ? Here is the warning message :
Use of uninitialized value at big2.pl line 33.
Use of uninitialized value at big2.pl line 33.
Also IS this the way to get the scalar value (the content)
of an array ? Hope to get a better method.
Thanks in advance

Does it require a PowerPC and if not do you know were I can obtain the

I would not call this "unreliable", and since you have only a few
variables, this should work fine. Another possibility would be to pass
the input via environment variables. This may be useful when those
values rarely change and get default values on login.

What problems do you see in passing variables, that cause you

Sometimes, but the point is that it's *THE ONLY WAY OUT*
of a read, etc. For example
$SIG{ALRM} = sub {die};
alarm 30000;
eval { $line = <STDIN> };
alarm 0;
Is the only way you can do a timed-out read.

Single-quoted strings ('...') are not subject to variable substitution.
Try,
print OUTFILE qq

instead.
Refer to perlop and perldata man pages to find more about qq and quoted

Subject: Simple question of Exclusion
Message-Id: <3328ed89.11036479@news.essex1.com>
I'm trying to make additions to a comma seperated variable database
while excluding entries that have already been added. This is what I
have stumbled to so far:
#!/usr/bin/perl
# update_daemon1.pl
$quit = 0;
while ($quit != 1) {
##### open initial_dbase and read each line into variables #####
open(ADD,"initial_dbase.csv") ;
while($line =<ADD>) {
($key, $date, $first_name, $last_name, $email,
$address1, $address2,
$city, $country, $state, $zip, $phone, $check_phone,
$fax, $check_fax, $contact,
$check_contact, $file, $category, $info, $check_call,
$new_category,
$check_new_category, $check_update, $graphic_url,
$ad_type, $listing,
$time, $language, $ad_headline, $price, $payby,
$cardtype, $cardholder,
$cardnumber, $cardexp, $compile_time) = split(/,/,
$line);
#print "$category\n" ;
#print "$file\n" ;
##### check to see if file exists or not and add new lines #####
if (-e $file){
open(READ_TEMP, "$file") or die "Can't open
$file, $!";
@some_lines = <READ_TEMP> ;
close READ_TEMP ;
unless (/$key/) {
unshift (@some_lines, $line) ;
@sorted_lines = sort by_number
@some_lines ;
open(NEW_FILE, ">$file") ;
print NEW_FILE @sorted_lines ;
close NEW_FILE ;
}
}
}
$quit = 1 ;
}
sub by_number {
$a <=> $b;
}
The part that is screwed up is the unless (/$key/) part.
What I'm trying to say is "Unless you find the key already in a line
(one complete record) in READ_TEMP unshift the new entry and sort the
results. I then want to print this to the NEW_FILE (READ_TEMP with the
added lines).
I don't know if this makes sense to anyone but I could sure use the
help.
Thanks in advance,

It is always an interesting experience for a native speaker of the
German language to follow discussions of English speakers about their
language. Assuming that I am not the sole foreign subscriber to this group,
would you mind explaining to us what's the problem with writing "the email"
(as in "did you get my email yesterday", or "what's in the email
today"), and why I should not cook my eggs in a frying pan (do I have
to give up fried eggs :-(?).

The largest databases in the world are running on Unix boxes.
Reuter has 300.000 users connecting to their Unix systems (from NCR).
Unix is growing up although ESA/MVS clearly have many things

Then again there are things you can do using Unix that would be hard

Again the issue isn't what is "best" in some undefined and undefinable

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
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
