One of the techs called me over to check something out. I get there and he's showing me a recursive listing of a directory on one of the Unix systems here. And it's going deeper, and deeper and deeper and deeper and deeper and …
“Hmmm,” I said. “Looks like it's cyclically linked.”
“It's not symbolically linked,” the tech said.
“Could be hard linked,” I said. I did a listing to show the inode nubmer. Then went down another level, and did another listing. Different inode numbers. “Guess not.”
“Guess the customer had a buggy script,” said the tech.
“Guess so,” I said.
I think it finally bottomed out around 40 or so levels.
