The <code>'''find'''</code> program is a [[directory (file systems)|directory]] [[Search_engine_(computing)|search utility]] on [[Unix-like]] platforms. It searches through one or more directory [[tree (computing)|trees]] of a [[filesystem]], locating [[Computer file|file]]s based on some user-specified criteria. By default, <code>find</code> returns all files below the current [[working directory]]. Further, <c(contracted; show full)

A single white space is needed to divide syntax elements when writing a find command. Otherwise, some usage error will come up...


== 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 find 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.⏎

==Examples==

===From current directory===
 find . -name 'my*'
This searches in the current directory (represented by a period) and below it, for files and directories with names starting with ''my''. The quotes avoid the [[shell (computing)|shell]] expansion - without them the shell would replace ''my*'' with the list of files whose names begin with ''my'' in the current directory. In newer versions of the program, the directory may be o(contracted; show full)[[fr:Find]]
