Subject: [kw-pm] Using backticks in Perl script
Message-ID: <170223.85474.qm@web58706.mail.re1.yahoo.com>

Hi All,
   I've been passed a script that does unzipping of files and I can't seem to get it to work on a Windows machine. The server I'm trying this on I have to VPN in to. I've commented out the code that is trying to unzip a file and decided to put a simplier command in and see if I can get that to work but still w/o success.

   my $testStr = "dir";   #--- line 1
   my $newTest = `$testStr`;
   print "<br>Test string returned :" . $newTest . "<br>";
        
   When I run the overall script I get errors on the third line of code above telling me <name of script.pl>: Use of uninitialized value $newTest in concatenation (.) or string at <name of script>.pl line 82.
   I'm trying this simplier example to see if I can get it working first, the piece of code in the script (I was passed) is trying to use the gunzip executable but w/o success (i.e. gunzip -cf <$filePath) using the backticks again. Any help would be appreciated. Thanks.

Rob

"dir" is a builtin command, and doesn't exist anywhere as an executable by
default. On my XP machine, I'd have to issue

     cmd /c "dir"

You would have the same problem on *nix with builtins if the shell didn't
interpret them. For instance, `setenv` does nothing when called from perl,
though it does from the command line.

(However, I doubt that this is your original problem -- most likely you've
created an unrelated problem by trying to make the script simpler.)

Perhaps you'd have better luck with a package from CPAN?
http://search.cpan.org/perldoc?IO::Uncompress::Gunzip

<http://search.cpan.org/perldoc?IO::Uncompress::Gunzip>I can't (be bothered
to) find if it's doing everything in Perl, or if it's calling a library
somewhere, but it should probably at least get around problems with system
calls.

If anyone is interested in giving a short talk in February, or March,
there is room for you. As Abram said, they really don't need to be fancy.
Or even be perl specific.  Just interesting. :)

We currently have two talks slated for February:

fishbot will present on some developments in Perl 6: "Modern Perl -
Module, Modernity and Marketing". And I will do a quick review of a python
CGI project I wrote which uses pExpect, a robust alternative to Expect.

Our February meeting is the 18th, a week Thursday. Hope to see you there.

I'll put a summary of my planned talk up on the wiki.  I might 
mention Perl 6 in passing, but it is explicitly not about Perl 6. 
It's a short investigation about what "Modern Perl" is, and then 
to me more interesting, what "Contemporary Perl" is.  Not an 
advocacy talk.

For the other talk to fill out the rest Feb, I'd love to see a Perl6
talk a quick demo of an operator or something neat like that.

Another alternative would be if someone would like to present something
about say a demo bot or an AI bot in the CS Club's tron ai competition.

There's a perl pack:

Tonight we've got two talks planned:

fishbot will present "Modern Perl - Module, Modernity and Marketing", a
discussion about the "Modern Perl movement", how Modern relates to
Contemporary and where we might be in the historic arc of Perl.

Daniel will do a quick review of a python CGI project he wrote which uses
pExpect, a robust alternative to Expect.

Also, with the pizza!  Before 5pm please add your name to

As usual we meet: 7pm in DC3323, University of Waterloo.
