Perl: Read directories and assign to array

I would like to read directories and assign to an array where the user can select a directory from the output. For example, a dir list will populate with a number assigned to each dir. I would like to ask the user to select the dir they want. TIA, I don't know what this would be called so I couldn't really search for it.

e.g.

1 - dir1
2 - dir2
3 - dir3
...

Hi ,

use readdir and file test operations .

readdir -- will give you all the contents of your present working directory in array format.

to select the directories from that array use file test operators.

Regards,
Penchal.

Or, instead of opendir/readdir/closedir, just use globbing:
Code:
@array = </path/*.txt>

will put the names of all .txt files into an array.
