There is no doubt whatsoever that foobar originated from fubar.
When did "baz" come into being and how? I saw it used for the first time
like 6 months ago.

\n in a double-quoted test string. (Your example uses single quotes,
which suppress this interpretation of backslash.) See "Learning Perl"
page 5: print ("Hello, world!\n"); or any other basic documentation.
Even though what actually gets written out depends on the operating
system, the difference shouldn't matter, because when read back in it
becomes the single character represented by \n once again.

How are your attempting to create multiline output? Could you post some
brief sample code? My guess is that you don't realize that the Perl
print function won't insert a terminal newline unless you ask for one,
using the (doublequote) escape sequence \n. Try this:
print "Line one\nand two\n";
print "...and three!\n";
When you run that, do you get three lines of output? If not, something
about your installation is seriously broken.
: How do I create a LineFeed/Carriage Return in Perl for:

\n in both cases. It expands to The Right Thing on each host system:
\x0A on Unix
\x0D\x0A on DOS/Windows
\x0D on Macintosh
and so forth. Do remember that \n only works in doublequotish contexts,
so don't do 'Hello\n', but rather "Hello\n".

Well, you basically have to give the permissions to modify files and
restart processes to anyone using your web server. That's generally not
considered a smart idea, but if you insist, go ahead.
However, there's nothing Perl specific to your question. In fact, the
answer to your question will be OS and/or server specific. Please ask
in the appropriate groups.

With all respect, this is a glib and totally useless response. I
followed your suggestion, and searched for "perl comment block", and
got 19 totally irrelevant responses (only 7 of which were from "perl"
groups, by the way). I don't want to waste more time refining the
search (adding "entire" reduced it to 1 irrelevant response, about
"Python").
If you point someone at Dejanews, please have the courtesy to try it
yourself first, then suggest the search keys. Otherwise,

this is a rather contentious thread that is full of flaming and
senseless posts like yours. people tend to get really worked up
over this subject. reading the past threads on this SAME EXACT
SUBJECT would have prevented you from making a fool of yourself.
>I don't want to waste more time refining the

i think this is the problem. i'm sorry that you don't have the skills
to do things on your own, but perhaps that is a sympton of the
fact that you also expect every post in usenet to explain the
universe.
>If you point someone at Dejanews, please have the courtesy to try it
>yourself first, then suggest the search keys. Otherwise,
i'm sorry that you are unable to find information on your own.
if you search only in the group comp.lang.perl.misc for "block comment",
i find about 100 responses. it seems like a fairly obvious thing to
do.
once you do that, count the number of times that this same subject has
come up, and look at the problems that each thread genereated.
now, think about the message that you posted to a world-wide medium. are
you sure this is the message you want to send about yourself to the
world?

See the perlpod manual page, distributed with perl. If you're on a
Unix-esque system, the command:
perldoc perlpod
should produce it for you. If not, you may have to grub around in
your perl program directories to find the documentation (but it's
almost certainly there). Failing all that, check at
http://www.perl.com for pointers to online versions of the Perl
documentation (but you're always better off knowing how to use the set
that's on your own system).

A faster way to do this:
find <directory> | xargs grep -l '<search string>'
The 'xargs' utility takes its stdin, appends it to whatever arguments its
given, and then executes the resulting command line. So, it calls only one
instance of 'grep' and passes it the list of files.

You know, this is the sort of question that gets newbies flamed around
here...you've asked an almost word-for-word FAQ:
perlfaq4/How_do_I_strip_blank_space_from_.html
(in the HTML version of the doc.) Read the FAQ. Study the FAQ. Check the
FAQ before posting. The FAQ is your friend. The FAQ answers questions
roughly 100 times faster than c.l.p.m, and much more reliably, too.

I use a product call CRISP. It will run on UNIX and on Windows. It color
codes perl. It also let's you split the screen and run a shell session in
another window. This makes it pretty handy to develop in one window while
you edited the perl in the other. It also understands many other languages,
such as C.
he following companies can be contacted for CRiSP availability, pricing,
information, support or general sales queries.

Yes, and that's pretty much all there is to it. Just send the appropriate
MIME type, and then send the binary data from the file.
Oh, and for future reference, there is a CGI group
(comp.infosystems.www.authoring.cgi) that deals with CGI issues. You can
probably find more help with things like this over there. This group deals
more with general Perl language issues such as syntax, modules usage and
such, and not so much with specific applications using Perl.
HTH!

Subject: Setuid and Solaris
Message-Id: <6h5svl$at3$1@nnrp1.dejanews.com>
I'm having some problems with making setuid scripts work on Solaris 2.6 under
Perl 5.004_04. I was finally able to pound it into shape, but still wonder
why it required _quite_ so many gyrations.
For example, I can understand why PERL5LIB is ignored (even though this app
requires access to a different set of libs depending on input parameters,
forcing me to play "use lib [dir]" games). However, a couple things still
have me howling at the moon, and I was wondering if anyone could shed some
light for me.
1) Setting $ENV{PATH} to _ANYTHING_ (e.g., '/usr/bin') generates an "Insecure
PATH in setuid" error. Playing the following game:
my $x = '/usr/bin'; $x =~ /(\w+)$/; my $xx = $1;
$ENV{PATH} = $xx;
Appears to work, but then generates "Insecure directory in path..." errors --
even after setting /usr/bin explicitly to mode 0644. The only way Perl will
let me execute any backticked expressions is to explicitly "delete $ENV{PATH}"
-- and leave it deleted. (Not to mention $ENV{ENV} and $ENV{CDPATH}, but I
don't really care about those for this application.)
2) The following code does NOT work, but instead generates an "insecure
dependency in ``" error.
my $bin = '/usr/bin/progname';
my $str = `$bin $args`;
Yet if I change it as follows, it works just fine:
my $bin = '/usr/bin/progname';
$bin =~ /(.+)$/; my $b = $1;
my $str `$b $args`;
I have to untaint a variable whose value I set explicitly from hardcoded
data? I do not understand this one AT ALL.
Any comments welcome...

Message-Id: <null>
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
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.
