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)
*'''-not expr''' Same as ! expr. 
*'''expr1 expr2''' And (implied); expr2 is not evaluated if expr1 is false. 
*'''expr1 -a expr2''' Same as expr1 expr2. 
*'''expr1 -and expr2''' Same as expr1 expr2. 
*'''expr1 -o expr2''' Or; expr2 is not evaluated if expr1 is true. 
*'''expr1 -or expr2''' Same as expr1 -o expr2
 but doesn't work as widely (since POSIX doesn't require it). 
*'''expr1 , expr2''' List; both expr1 and expr2 are always evaluated. The value of expr1 is discarded (though its side-effects occur); the value of the list is the value of expr2. 

 find . -name 'fileA_*' -or -name 'fileB_*'

This command searches files whose name has a prefix of "fileA_" or "fileB_" in the current directory.

 find . -name 'foo.cpp' -not'!' -path '.svn'

This command searches for files with the name "foo.cpp" in all subdirectories of the current directory (current directory itself included) other than ".svn".   We quote the ! so that it's not interpreted by the shell as the history substitution character.

==Type filter explanation==

'''-type''' ''option used to specify search for only file, link or directory.''
Various type filters are supported by find, they are activated using the
