Well, other than THAT IS A REALLY BAD  IDEA - your web server probably
doesn't have enough write premissions to create files in your CGI-BIN.

The cgi-bin is prolly owned by root - which is the secure way - if it is
owned by a regular userID, then that is not as secure, but still likely
better than allow the ID the server runs as access.

I would suggest you purchase Apache Server Administrator's Handbook, ISBN: 
0-7645-3301-1  and you may want to get the Official Guide to Programming
with CGI.pm, ISBN:
0-471-24744-8  and/or CGI Programming with Perl, ISBN:  1-56592-419-3.

Each book is about $30...

PS - I teach CGS2283 at FCCJ - you may want to sign-up in the Fall.  See

Also, you should join Jax.PM the web page explains how to get on the list;
the members there can explain how this is a really bad idea as well  :)

To answer your question about 'With Out' using SYSTEM() - that too is a bad
idea.  Using system() is one of the better things to do.  The alternative is
back-quotes which are VERY bad - about the same as allowing a web browser to
write in your cgi-bin...

Hey Perl addicts:

I was surfing the net for some kind of a website offering perl
assitance, and
I stumbled into your page.

I didnt know there was a perl group, right here in Jax... neither I know
if
you offer assitance, but perhaps you can help me.

Im a webmaster trying to learn Perl, and although I've checked several
books i
cannot seem to find the solution to a small perl problem.

I would like to untar a tar.gz file in my cgi-bin, not via telnet but
through
a few lines of code. 

I was suggested using system as follows.

#!/usr/bin/perl 
print "Content-type: text/html\n\n"; 
system("tar xvfz template.tar.gz");
print "Done, your file is untared\n";

If I use tar xvfz template.tar.gz it works, but through the script it
doesnt.

Is there a way to do this without using system..???

I hope you can help
Regards
Sebastian
