POSIX Protection From Infinite Output
Real-world filesystems often contain looped structures created through the use of hard or soft links. The POSIX standard requires that
Thefind utility shall detect infinite loops; that is, entering a previously visited

loop, find shall write a diagnostic message to standard error and shall either recover
its position in the hierarchy or terminate.Read more about this topic: Find
Famous quotes containing the words protection, infinite and/or output:
“No: until I want the protection of Massachusetts to be extended to me in some distant Southern port, where my liberty is endangered, or until I am bent solely on building up an estate at home by peaceful enterprise, I can afford to refuse allegiance to Massachusetts, and her right to my property and life. It costs me less in every sense to incur the penalty of disobedience to the State than it would to obey. I should feel as if I were worth less in that case.”
—Henry David Thoreau (1817–1862)
“Nothing could his enemies do but it rebounded to his infinite advantage,—that is, to the advantage of his cause....

—Henry David Thoreau (1817–1862)

And gave her mother forty whacks;
