Re^2: Directory tree explorer with stats reporting

Seems like you encountered a state where the path length may be more than the program (underlying -s function) could handle. I can easily reproduce it by creating a circular symbolic link on FreeBSD. After 32|33 levels, size is undef, resulting in Use of uninitialized value in adddition <+> ... message.

I will post the updated program -- unless somebody beats me to it -- to not follow symbolic links.

Update (later that day): Problem that i observed was due to circular symbolic links (unresolved till 3[23] levels); there was no problem w/ 60+ levels of directories.

Not to pat myself on the back, but rather to point out the value of even simple testing: Someone downvoted my original post in this thread; probably because they didn't like the fact that I mentioned that I hadn't had time to dig into the code myself. Or perhaps because they thought I had done what GrandFather initially suggested was the problem: i.e. just copy pasted the code instead of downloading it. The subsequent posts to this thread demonstrate that my initial post had value: [id://parv] looked at this(and what the other posters had to say), found the bug and fixed it. The poing: even simple testing is worthwhile if you provide some detail for others to work with. Maybe I'm way off base here..but I think not...:) By the way..thanks for the fix, [id://parv] Scott	[reply]
