Hi,

if you have a file name like this:

0123thisIsAFile.html

What would be the correct regular expression to extract the integer from that file name?

And if you have the answer handy, how do you get an array of the file names in a directory?

How can you "substract" a string from another string? Speak, you have two strings like "http://www.go.com" and "http," and you need the characters that only exist is one of them.

Thank You So Much, I love you all,

Malte

*wow, this text box is huge ;)*

1) If the "thisIsAFile" is not variable (it's the same for all the files, here's the code:

if ($filename =~ /^(.+?)thisIsAFile.html/) { $integer = $1 }

2) Code:

$directory = "/home/usr/yourname";
opendir(D, $directory);
@files = readdir(D);
closedir D;

3) Code:

$string1 = "http://";
$string2 = "http://www.go2net.com";
foreach $letter (split(//, $string1)) {
$string2 =~ s/$letter//g;
}

Note that this last code will delete all H's from $string2, all T's, all P's and so on.

Cheers!
