The possible search criteria include a [[pattern matching|pattern(contracted; show full)

The [[GNU findutils|GNU]] <code>find</code> has a large number of additional features not specified by POSIX.

== POSIX protection from infinite output ==

Real-world filesystems often contain looped structures created through the use of [[hard link|hard]] or [[symbolic link|soft links]].  The [[POSIX|POSIX standard]] requires that
 The <code>find</code> utility shall detect infinite loops
sss; that is, entering a previously visited
 directory that is an ancestor of the last file encountered. When it detects an infinite
 loop, <code>find</code> shall write a diagnostic message to standard error and shall either recover
 its position in the hierarchy or terminate.
