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
directory that is an ancestor of the last file encountered. When it detects an infinite
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:
“The best protection parents can have against the nightmare of a daycare arrangement where someone might hurt their child is to choose a place that encourages parents to drop in at any time and that facilitates communication among parents using the program.

—Gwen Morgan (20th century)
“Hath not the morning dawned with added light?
And shall not evening call another star
Out of the infinite regions of the night,
To mark this day in Heaven? At last, we are
A nation among nations; and the world
Shall soon behold in many a distant port
Another flag unfurled!”
—Henry Timrod (1828–1867)
