Dear List,
I am trying to write a cgi-script that adds a new user to my linux box via a
web based form.
The trouble is, is how do I pass variables to the program "passwd"?? This is
so that when the password is sent via the form, it erncrypts the password,
and adds the user??? Has anyone got any
You cannot call passwd with the password as a parameter.
(btw. this is a feature, not a bug :-)
Look at the Expect Module (available on CPAN). It lets you automate
interactive programs (like passwd).
hope that helps,

Hi All
I am trying to use flash on pages that include Perl scripting. I have
had a look at the code and I am not sure whether it is Java or
JavaScript.
Here is a example.
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array;
for(i=0;i<(a.length-2);i

My reply is slightly different to the others. I am going to define a cgi script as one
that you send to a browser. If not, it is just a perl script and cron is what you
need. If however you need information on a browser to be update then you can specify
refresh in thdocument you send to the bro

No. I had a bad regex weekend (as Paul could personally attest to).

But if 'you' are using seek why have carriage returns anyway? It's not
usually a good idea to have paper control embedded in fixed length records.
If the problem is to print it then that can be done with a four line perl

Hi, I am fairly new to perl, and have a few questions about a small

delimited by colons. Eg...
Field One:Field Two:Field Three:Field Four
I know the first couple of fields are specific and will always be there, but
after that,
Does a package exist that will read an HTML document and generate an Apache::CGI or

First part:
You get the size of an array by using it in a scalar context.
Sounds complicated?
Scalar context means that the left side of an assignment is a
scalar. So you just write:
$size = @a;
and you get the size of the array @a.
Another method would be to get the index of the last element a
A cool control structure in perl is the for or foreac loop. With it you

construct.

This is entirely correct.
But for those of you who prefer a more explicit syntax, you can put any

A rather clever way to emulate locking is to use mkdir() and rmdir().
