perl split funciton - special character "/"

HI,
I have a directory structure. /abc/def/ghi/
I want to store it into array.
So that if I do a pop function on that array I can easily go to previous directory.
But how can i split and store it.

@Directory = split(/\//,$DirectoryVarialbe)

That doest works. Any other escape sequence should be given??

Kindly help.

Perl split function

Hi,
It should work fine. I tried the following...

Code:
#!/usr/bin/perl -w
use strict;

# Program to accept a file path and store it in a array

my $dir = "/abc/def/ghi/";

my @Dir = split(/\//, $dir);

pop(@Dir);

my $PreviousDir = join("/", @Dir);
print "The original Directory is $dir\n";
print "The new Directory is $PreviousDir\n";

Following Perl 5.6.1 test code works for me:

Code:
#!/usr/local/bin/perl -w

my $DirectoryVariable="/abc/def/ghi";

my @Directory = split(/\//, $DirectoryVariable);

print "@Directory";

Are you running into the first element being the "/" and undef as a problem?

Thanks for your reply. The escape sequence worked. Initially i managed to load the array without even spliting the fields from the sclar variable. That was in an attempt of trail and error. Now I forgot how I did that though.
