Simple Question, hope the answers is too!
I want to get the date/time of a file. It's a backup file and I want to
display its date so that users can decide whether to restore it or not

"its date" is (very) ambiguous. Which "date" do you want?
In any case, see
perldoc File::stat
for atime, mtime and ctime (just make sure you realise
that ctime is not creation time).
Or...do you want the date that the file was backed up? If
so, your backup software may well have to maintain some
kind of database. That's another story in itself, so
let's leave that one dangling until there's some more info
on the table.

Modern Perl installations include the "perldoc" command with the
capability of searching the Perl FAQs that are also included with
Perl.
In this case, running:
perldoc -q time
finds:
How do I get a file's timestamp in perl?
as the second hit. Check there for you answer.

Better would be to check the FAQ in advance.

Not encrypted data, hidden data.
A compiled binary executable (e.g. a C program) can have execute-only
permission.
An interpreted script cannot (under normal circumstances) have
execute-only permission.
You can get arround this using a SUID script.
If you use sperl and hack out the check that prevents you using sperl
on non-SUID scripts you don't even need to use an SUID script.
If you are using an SUID script anyhow you may as well leave the
script source readable and put the password in a file that's only
readable by the user to which the script SUIDs.

Hi,
Thanks every one who replied -- So it seems that no one has ever
done this in Perl before?
I'm trying to use the following RE to identify quote email lines:
((?:>|:|\S+>)\s*)+
This will identify the following sample quoting:

Please suggest that if this is appropriate, and most important, how
can I determine the quoting level? (Answer for above 3 lines would
be 3, 2 and 1)

I find it raised, but that's compared to when I'm running Windows normally.
I find it ironic that as MS banish the command line, MacOS gains one (so I
believe)

Well, it's not nearly as embarrassing as when you after a session in

Windows NT and 2000 have similar path/file name completion. Set
the value of the REG_DWORD CompletionChar in the registry key
HKEY_CURRENT_USER\Software\Microsoft\Command Processor to, say, 9
(TAB key). This works well for navigating Windows-ish "folders"
with names containing spaces.

Okay, how about this:
open WORDS, "/usr/dict/words" or die $!;
open PAGER, "| more" or die $!;
print PAGER $_ or last while <WORDS>;
close PAGER or die "Pager failed ($?): $!\n";
Of course, the other solutions, which don't use an external program,
work too. But why reinvent the wheel, when you're bound to do it badly?
A good pager program will do a lot more than just <STDIN>.

The question has no content relating to Perl, and would be more appropriate
to comp.infosystems.www.authoring.cgi.
However, evidence suggests you're using MSIE, which is notorious for
ignoring a document's declared Content-type, preferring instead to act on
its own flawed intuition. If there is a solution, it's more likely to be
known by the readers of the previously mentioned group than to the readers
of this group.

My apologies for the subject heading... it's as flawed my IE browser. It was
thought to be a Perl scripting problem which is why the message was posted
here. Nonetheless, greater attention will be given to all future scripting

There are a number of methods to attain a system type.
I am not sure which of these methods is most effective
and most quick. A number of files exists which can be
opened and indexed for an operating system or, a system
call for version can be made. Appears the relative time
lags for open () and system () are closely the same.
A problem with checking for files inherent to a specific
operating system is a directory path may or may not be
correct, depending on installation method and, depending
on what changes have been made, subsequently. This method
is inherently less reliable than a system call.
Below my signature is a method which will return an
operating system version for DOS / Windows machines
and return a false 0 (zero) for the system call itself.
This is one of my typical rogue methods which works well
and, no regulars here have discussed. A catch is a very
slight time lag, less than a second, due to a system call
return evaluation.
You will do better to simply test for flock ability. It
is illogical to use an operating system type as a deciding
factor on flock or not flock. Checking a system type
introduces unwarranted program activity; flock will
either work or not work regardless of system type.

I feel some guilt for pulling a con like this
on some of you sissified geeks. This is unfair
to those whom are not prone to pitching a total
anal retentive fit.
This snippet will perform the same function as
my two lines of code snippet above:
system (ver);
Perhaps if my little Godzilla, who is actually taller
than me, didn't make me attend church every Sunday,
I could pull a con like this without feelings of guilt
and, would not suffer a lightening bolt burnt butt,
each Sunday.
I must work on a way to con God into not striking my
big butt with one of Her lightening bolts at church.
It is only this blistering fear which motivates me
to sometimes confess my sins to you geeks.

Subject: lib files stopped working

I have several scripts which make use of a couple of small libraries. They
"used" to work just fine, then all of a sudden -- WHOMP! Now they don't work at
all, I just keep getting 500 errors.
Here is a sample of what I had that worked:
---
#!/usr/bin/perl
require "cooklib.pl";
require "cartlib.pl";

Now when I use this I get a 500 error. *If* I plug the subroutine into the main
perl file it works fine, I just can't seem to get a call, *any* call to a lib to
work.
Can, more accurately will, anyone help me?

If what you want is an actual web-usenet gateway, I'd suggest
http://directory.google.com/Top/Computers/Usenet/Web_Based/
as a starting point. Some of those have GPLed their source.

Maybe PHP is only for CGI but I've been programming in perl for over six
years and I've never done anything even remotely involved with CGI.

Web servers can use quite a variety of languages to generate dynamic
content. In some cases they call an external program and pass connection
info using a predefined API (CGI) and send the program's output directly
to the client, while in other cases the interpreter is embedded within the
server and interprets codes embedded within a prototype HTML document
(shtml).
PHP is a scripting language that is exclusively (AFAIK) interpreted by the
web server. It has no other use other than to generate web pages. It
performs this task well.
Perl is a general-purpose scripting language. It can be launched (CGI) or
embedded (eperl, mason) to generate web content. Perl can also be used
without a web server to run batch, text-interactive or GUI programs. Perl
is rapidly replacing bash/sh shell scripts as the main scripting language
used to maintain Linux computers.
Other languages to consider for use on web servers are Python, Ruby and
Java (for all platforms) and VisualBasic Script (for Microsoft IIS ASP
pages).

The naming convention of the USENET news goes back more than 20 years now.
The alt.* groups are less regulated in terms of creation and content than
the other heirarchies and often duplicate content of the other TLD groups.
You would have to check the charters of the groups to be sure what the
intent was, but can normally infer it from the name:
comp.lang.perl.misc - discussion of perl language constructs not covered
by another comp.lang.perl newsgroup
alt.perl - general discussion of perl syntax, advocacy, religious wars
alt.comp.perlcgi.freelance - presumably an employment advertisement group
YMMV.

ok. first note that you should not top-post.
by that, I mean to write a follow up at the start of an article,
and then quote the whole of the article you are replying to, including
signature and everything
you should quote relevant parts, snip away the rest and put your
comments after the parts you are replying to

here you are essentially creating a command to pass to the shell
if $email,$ADDRESS and $MSGS come from an untrusted source, you must be
very careful about this kind of construct.
untrusted does not necessarily mean malicious, but can also just mean
non-expert.
the exact traps depend on what shell or operating system will execute
the command, but as a rule you should only allow the input to conform
the the strictest patterns you can.
examples:
a blank (or space only) $email will make the $ADDRESS
be interpreted as the email value
a space in the $email will make the $ADDRESS be the MSGS
a semicolon or pipe in $email could have disastrous effect:
'|rm -r *.*' might have some side-efects
so what you should do is make sure these variables only contain
alphanumerics, underscore,period and @
if it turns out some of them need more characters, enable them
one by one, after considering the effect they may need
