In Unix-like and some other operating systems, find is a command-line utility that searches through one or more directory trees of a file system, locates files based on some user-specified criteria and applies a user-specified action on each matched file. The possible search criteria include a pattern to match against the file name or a time range to match against the modification time or access time of the file. By default, find returns a list of all files below the current working directory.

The related locate programs use a database of indexed files obtained through find (updated at regular intervals, typically by cron job) to provide a faster method of searching the entire filesystem for files by name.

Famous quotes containing the word find:

    Only in men’s imagination does every truth find an effective and undeniable existence. Imagination, not invention, is the supreme master of art as of life.
    Joseph Conrad (1857–1924)

    Every man who has at last succeeded, after long effort, in calling up the divinity which lies hidden in a woman’s heart, is startled to find that he must obey the God he summoned.
    Henry Brooks Adams (1838–1918)

    To find the length of an object, we have to perform certain
    physical operations. The concept of length is therefore fixed when the operations by which length is measured are fixed: that is, the concept of length involves as much as and nothing more than the set of operations by which length is determined.
    Percy W. Bridgman (1882–1961)
