thanks for the reply. It was a question for my project, that was checking my capability.I am learning perl from the scratch, a beginner. I used glob, but that gave me the array of files in the current directory, or the directory which I have passed to the glob function, it is not giving me the files in the sub directory. How do i do that?. i need to search for all the files in the disk, and need to push the files into an array,then take the files for processing. I need to avoid cyclic links, but didn't get the idea how to check the cyclic link? Also i need to find a way without recursion?. please guide me | [reply] |

As per toolic's reply, use opendir/readdir.

Have a look at readlink.
Also i need to find a way without recursion?
Any other restrictions? Can we use computers? Recursion is the only by far the most sensible approach when dealing with an arbitrary depth of sub-directories.
Update: Slightly toned down the recursion encomium!

Recursion is the only...
One way might be push all the dirs onto a @stack as you find them and shift them off one at a time to process them. Then you can convince yourself you're not using recursion which I find easy to do. :-)
