In [[Unix-like]] and some other [[operating system]]s, <code>'''find'''</code> is a [[command-line utility]] that [[Search engine (computing)|searches]] through one or more [[directory tree]]s of a [[file system]], locates [[Computer file|file]]s based on some [[user (computing)|user]]-specified criteria and applies a user-specified action on each matched file. The possible search criteria(contracted; show full)
 -name 'catalina.out' \) -size +300000k -a -size -5000000k`; do 
    cat /dev/null > $file
done
</source>
The units should be one of [bckw], 'b' means 512-byte blocks, 'c' means byte, 'k' means kilobytes and 'w' means 2-byte words. The size does not count indirect blocks, but it does count blocks in sparse files that are not actually allocated.

* <code>[[Llocate_  (Unix)|locate]],</code> is a Unix search tool based on a prebuilt database, and therefore it is faster and less accurate than <code>find</code> (because the database may not be up-to-date).that searches through a prebuilt database of files instead of directory trees of a file system. This is faster than <code>find</code> but less accurate because the database may not be up-to-date.
* <code>[[grep]]</code> is a command-line utility for searching plain-text data sets for lines matching a regular expression and by default reporting matching lines on [[standard output]].
* <code>[[tree (Unix)|tree]]</code> is a command-line utility that recursively lists files found in a directory tree, indenting the file names according to their position in the file hierarchy.
* [[GNU Find Utilities]] (also known as findutils) is a [[GNU package]] which contains implementations of the tools <code>find</code> and [[xargs]].
* [[BusyBox]] is a utility that provides several stripped-down Unix tools in a single executable file, intended for embedded operating systems with very limited resources. It also provides a version of <code>find</code>.
