Subject: (NT) Which command processor gets used for "system"?
Message-Id: <350ba8ee.82641261@news.ican.net>
I have installed both the ActiveState (5.003) and the Standard (5.004) versions
of PERL. I generally use the 4NT.EXE or TCSH.EXE command processor and I have
%COMSPEC% set to 4NT.EXE. PERL 5.003 appeaers to use %COMSPEC% for "system"
calls while 5.004 seems to use the NT default of CMD.EXE (see below for results
I get under any command processor). Is this actually the case, and do I have any
control over which command processor is used by the Standard version (5.004),
for example with an environment variable?
v:\> k:\perl5003\bin\Perl.exe -e "system 'ver"' [Active State]
4NT 3.01A Windows NT 4.00
v:\> k:\Perl5004\bin\perl.exe -e "system 'ver'" [Standard]
Windows NT Version 4.0
Thank you.

Message-Id: <6eelol$631@julius.ling.ohio-state.edu>
well, i can come up with at least one situation where not closing
filehandles leads to a problem. i occasionally write scripts that
loop through a directory, opening each file, looking at its contents,
and then moving it somewhere. if i don't close the filehandle, then
the last file in the directory doesn't get moved. close filehandles,
and of course everybody gets moved to wherever it is that they ought
to go.

Note that \w matches a single alphanumeric character, not a whole word.
To match a word you'd need to say \w+.

Steve is both correct and incorrect. It's true that someone could copy
your GIF, but incorrect that the question has nothing to do with Perl.
One answer off the top of my head is to make the GIF dynamic. Off the
top of my head, here's a suggestion. Using SSI, put the current time and
date at the top of the page. Have the PERL (See, Steve?) CGI program
return a built-on-the-fly GIF with the time and date in it (see almost
any web counter CGI for how to imbed numbers in a GIF). Tell users that
date and time must match (and must be the real date and time) or the
page is fake.
Hope this helps.

It's when someone asks a question which is practically word-for-word a
FAQ, or is such a basic item of language syntax that reading the first 40
pages of the Llama would answer it, that the flamethrowers come out.

I categorically refuse to respect an individual who would rather waste the

others on this group agree with me. No, programming is not an easy thing;
I think part of the problem is that people *expect* it to be easy, expect
to be able to approach it as one would a (say) Windows word processor --
playing with it to learn, rather than reading a single word of the doc
(on- or offline). This simply will not work, and those who expect it to

Yes, but I'm sure you tried to use the non-human resources available to
you to learn, saving your questions to humans for those cases when you
needed explanation, not information.

Yes, I do. comp.unix.wizards was created once-upon-a-time as a place for
unix wizards to hang out. My understanding is that it rapidly became a
smoking crater. Why? every newbie with a question felt that the best
answers came from the wizards, and therefor should be asked in the
wizards news group. I mean, whou would _you_ ask a question of? a
fellow newbie, or Larry Wall?

Read the docs. If you continue having problems, give enough information
about what you're trying to do, what platform you're on, and what you've

To put the output of ls into an array:
@ls = `ls -l`;
To get just the columns you want, use unpack. Effective Perl Programming, by
Joseph N. Hall, pg 73, shows an easy way to do this.
Basically, to get a column starting at position 5 that is 7 characters long:
$col = unpack('@5 A7', $line);
To get several columns:
@cols = unpack('@5 A7 @20 A6 @32 A12', $line);
Hope that helps.

I have tried both commands such as `mkdir [dir]` and mkdir($dir,0777),

What seems strange to me is that no error is returned. The script

A real PERL guru desperately needed :-)
I am trying to send a e-mail with formatted text. I just get a boring
"internal error" message from the server.. :|
I have set the rights for the script to 755 and it's uploaded as ASCII.
The path to PERL on the server is correct. Enclosed is an example of
what I want to do.
Does anyone know what wrong I do? All help is highly appreciated!

Because the hyphen is not a \w character and is hence a word boundary. Hence

No. It is about as useless as advising someone to search Dejanews only to
turn up dozens of postings, containing your keywords, advising people to
search Dejanews.
Having never been bitten, perhaps Ian and I, and dozens of intimidated
lurkers, would benefit from a more complete explanation of what makes Perl4
less secure than Perl5.
Note that Ian did not explain whether or not his project was being

Hello
Anyone come up with a good way to read user input in win32 without echoing it
to screen? (Yep, to read a password) All tips I've seen tell me how to do it
in unix (system "stty -echo"). I'm considering writing a C-program to call
from perl to accomplish this, but that's only my last option since I'd like to
stick in Perl. Anyone done this?
If not, what's the best way to glue the little C-progt to perl as nicely as
possible. Any web-sites explaining this? Thanks in advance for any help.

Subject: Re: You have 1 message(s) - how to print plurals?
Message-Id: <6eeli1$61m@julius.ling.ohio-state.edu>
my favorite language has many words which are inherently plural; to
make them singular, you have to add something to them, in the same way
that in english one adds something to a word to make it plural. e.g.,
siwa 'bees'
siwatat 'bee'
jome 'baboons'
jometat 'baboon'
notice any trend in the referents of inherently plural nouns? hint:
fish/fish, ants/ant, and brother-in-laws/brother-in-law belong to the
same class.
but, back to perl: problems with getting a finite state machine to
handle agreement markers, such as the plural, are one of the classic
chomskyan arguments against using finite state machinery to describe
language. we know that perl's re's aren't really "regular," though,
and therefore aren't finite-state. so, how far can we push a language
with constructs like $+? i guess i think you'd need an augmented
transition network, but if you set its values with reference to what
was matched by $+...
just speculating---

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.
