I want to create a directory and a sub directory in it!

I was using: mkdir($dir,0777);

This will work for the last sub directory name.
Forexample:
if $dir="/home/shop/test/one";
the code will create a new directory in dir test if the dir tes already exists!

But what if the directory test does not exists?
What code do I have to use to check if dir home is available - if not create - if shop is available - if not create - if shop is available - if not create - and at last if one is available - if not create!

Ooops. Let's correct that:

use File::Path;

mkpath( $dir, 0, 0777);

The documentation can be viewed at:

I file::path a standard module/ function in perl?
If not can it be done with standard modules/ functions?

Yes, File::Path should be a standard part of your Perl distribution, if it's recent enough. I have it on 5.6.0.

Yes, you can do it with plain Perl, but that would require breaking up the pathname into components, making each directory if it doesn't already exist, and fixing the modes on the directories after you've created their subdirectories. In short, most of the code in the File::Path module.

On a Unix or Linux system, you could use

system( "mkdir -p $dir");

if the default permissions are acceptable.

I use:

use File::Path;
mkpath( $dir, 0, 0777);

But the rights will be set to 0755?
What is wrong?
