Synopsis

find [directories] [expression]

The find command searches one or more directories (and their subdirectories recursively) for files matching certain criteria. It is very powerful, with over 50 options and, unfortunately, a rather unusual syntax. Here are some simple examples that search the entire filesystem from the root directory:

Find a particular file named myfile:

find / -type f -name myfile -print

Print all directory names:

find / -type d -print

Print filenames ending in “.txt” (notice how the wildcard is escaped so the shell ignores it):

find / -type f -name \*.txt -print

Useful options

-name pattern

-path pattern

-lname pattern

The name (-name), pathname (-path), or symbolic link target (-lname) of the desired file must match this shell pattern, which may include shell wildcards *, ?, and []. (You must escape the wildcards, however, so they are ignored by the shell and passed literally to find.) Paths are relative to the directory tree being searched.

-iname pattern

-ipath pattern

-ilname pattern

The -iname, -ipath and -ilname options are the same as -name, -path, and -lname, respectively, but are case-insensitive. (Even though the OS X filesystem is case-insensitive, the find command is case-sensitive when it matches filenames.)

-regex regexp

The path (relative to the directory tree being searched) must match the given regular expression.

-type t

Locate only files of type t. This includes plain files (f), directories ...
