First off, you need to make an array. All you have are some scalars with
similar names. You could use symbolic references
I was able to get the script running by adding
'perl' to the path. Thus, the command line
read
perl txt2html.pl sample.txt > sample.html
This did not work on the original box I
was working on, but on a different box, which
makes me think it is something to do with
the system setup, maybe

I downloaded a script that can convert a plain text
file to HTML, called txt2html.pl . It starts
with #!/usr/bin/perl, which should mean I can treat
it as an executable at the prompt, after I've
performed a chmod to make the file executable.
I did this and at the prompt, I type

Hi,
About the POP3Client module..
I have it work almost perfectly, apart from one part: when I try
to delete a message on the pop server I get an error asking for
auto/Mail/POP3Client/delete.al
I know .pl, .pm, .cgi etc files but what is this .al file?! And
where do I obtain it? (cannot find

printf "%b\n" for @ARGV;

It is actually much, much easier than that Brad. Perl has a bitwise
AND operator ( see perlop ):
how do you get off this list?

Hi,
Is there a way to convert two numbers from decimal to binary, and AND them

You could return the data by reference... The documentation is at
perldoc perlref
But in summary it would be
sub parse
{
my $hashRef = {};
$hashRef->{ONE} = 45;
return $hashRef
}
my $result = parse();
print $result->{ONE};

I have used join in order to make one big line of a document for searches such as the
one you suggest. Also, in another script I did this:
open(FILE,"$_");
my $txt = "";
$searchfile = $_;
while () {$txt .= $_;}
close(FILE);
## Search $txt for $string; if it is found, write the name
To get a value out of a subroutine you need to use the
return function. So if your sub creates the hash and
you want to do something with it in the script
outside, do something like;
%newhash=subroutine(values);
I believe you may also simply reference the hash
within the subroutine, but you shou

There is no array in the code given (but there probably should be).

So your saying that Perl can handle calculating cosine while iterating
through Pi?
for my $inc (-3.14159 .. 3.14159)
{
push @result, cos($inc);
}
Come on... C style for loops have their place.

To add to the answer(s) already given...
for ($i=1 ; $i<4 ;$i++){
print $sup($i);
}
is actually quite cumbersome, and very 'C'-ish... Let's make it more
Perl-ish...
for my $i (1..4){
print $i;
}
There is not need to have to deal with incrementing and checking conditions
in loops - Perl

Because, basically, you can't do that. To get the result you want, you
have to do this instead:
# Begin perl
i have this program:
$sup1='a';
$sup2='b';
$sup3='c';
for ($i=1 ; $i<4 ;$i++){
print $sup($i);
}
but give error, why???
You need to use the -l parameter to specify the login name
ssh 192.168.2.21 -l arfan
you can type ssh --help to get a list of params

Thanks for the pointer! Knowing "DBI" and the references are great.
IndigoPerl has mSQL and faq has the syntax or exampled script. Many thanks!

Keep in mind that the crypt() function is ONE WAY! You can encrypt, but
not decrypt.
This may sound useless, but what you do is to encrypt what the user sends,
ecrypt it, then compare the encrpted version with the encrypted password.
If the two match, then the password was correct.
