Usage: /usr/bin/find [-H] [-L] [-P] [-Olevel] [-D debugopts] [path...] [expression]
Default path is the current directory; default expression is -print.
Expression may consist of: operators, options, tests, and actions.
Operators (decreasing precedence; -and is implicit where no others are given):
( EXPR ) ! EXPR -not EXPR EXPR1 -a EXPR2 EXPR1 -and EXPR2
EXPR1 -o EXPR2 EXPR1 -or EXPR2 EXPR1 , EXPR2
Positional options (always true):
-daystart -follow -nowarn -regextype -warn
Normal options (always true, specified before other expressions):
-depth -files0-from FILE -maxdepth LEVELS -mindepth LEVELS
-mount -noleaf -xdev -ignore_readdir_race -noignore_readdir_race
Tests (N can be +N or -N or N):
-amin N -anewer FILE -atime N -cmin N -cnewer FILE -context CONTEXT
-ctime N -empty -false -fstype TYPE -gid N -group NAME -ilname PATTERN
-iname PATTERN -inum N -iwholename PATTERN -iregex PATTERN
-links N -lname PATTERN -mmin N -mtime N -name PATTERN -newer FILE
-newerXY REFERENCE -nouser -nogroup -path PATTERN -perm [-/]MODE
-regex PATTERN -readable -writable -executable
-wholename PATTERN -size N[bcwkMG] -true -type [bcdpflsD] -uid N
-used N -user NAME -xtype [bcdpfls]
Actions:
-delete -print0 -printf FORMAT -fprintf FILE FORMAT -print
-fprint0 FILE -fprint FILE -ls -fls FILE -prune -quit
-exec COMMAND ; -exec COMMAND {} + -ok COMMAND ;
-execdir COMMAND ; -execdir COMMAND {} + -okdir COMMAND ;
Other common options:
--help display this help and exit
--version output version information and exit
In -newerXY, XY stands for the combination [aBcm][aBcmt]; see find(1).
Valid arguments for -D:
exec, opt, rates, search, stat, time, tree, all, help
Use '-D help' for a description of the options, or see find(1).

Examples (22) from the manual page, untested
find /tmp -name core -type f -print | xargs /bin/rm -f
Find files named core in or below the directory /tmp and delete them.find /tmp -name core -type f -print0 | xargs -0 /bin/rm -f
Find files named core in or below the directory /tmp and delete them, processing filenames in such a way that file or directory names containing single or double quotes, spaces or newlines are…proggy | find -files0-from - -maxdepth 0 -type f -empty
Given that another program proggy pre-filters and creates a huge NUL-separated list of files, process those as starting points, and find all regular, empty files among them:find . -type f -exec file '{}' \;
Run file on every file in or below the current directory.find / \
Traverse the filesystem just once, listing set-user-ID files and directories into /root/suid.txt and large files into /root/big.txt.find $HOME -mtime 0
Search for files in your home directory which have been modified in the last twenty-four hours.find /sbin /usr/sbin -executable ! -readable -print
- Search for files which have read and write permission for their owner, and group, but which other users can read but not write to.
- Search for files which are executable but not readable.find . -perm 664find . -perm -664
Files which meet these criteria but have other permissions bits set (for example if someone can execute the file) will not be matched.find . -perm /222
- Search for files which are writable by either their owner or their group.
This will match a file which has mode 0777, for example.find . -perm /220
$ find . -perm /u+w,g+w
$ find . -perm /u=w,g=wfind . -perm -220
$ find . -perm -g+w,u+w
All three of these commands do the same thing, but the first one uses the octal representation of the file mode, and the other two use the symbolic form.find . -perm -444 -perm /222 ! -perm /111
$ find . -perm -a+r -perm /a+w ! -perm /a+x
Both these commands do the same thing.cd /source-dir
$ find . -name .snapshot -prune -o ( ! -name '~' -print0 )
| cpio -pmd0 /dest-dir
- Copy the contents of /source-dir to /dest-dir, but omit files and directories named .snapshot (and anything in them).find repo/
( -exec test -d '{}/.svn' ;
-or -exec test -d '{}/.git' ;
-or -exec test -d '{}/CVS' ;
) -print -prune
The construct -prune -o ( ...find tree -printf 'device: %D path: %p\n'
Normally, find will search inside directories which happen to be mount points.find tree -xdev -printf 'device: %D path: %p\n'
The -xdev option causes find to visit the mount point, but not the items within that directory:find tree -mount -printf 'device: %D path: %p\n'
If we specify -mount we will not visit the mount point at all:find /tmp -type f,d,l
- Search for several file types.find /tmp ( -type f -o -type d -o -type l )
- Search for files with the particular name needle and stop immediately when we find the first one.
Search for files, directories, and symbolic links in the directory /tmp passing these types as a comma-separated list (GNU extension), which is otherwise equivalent to the longer, yet more portable:find / -name needle -print -quit
- Demonstrate the interpretation of the %f and %h format directives of the -printf action for some corner-cases. Here is an example including some output.find . .. / /tmp /tmp/TRACE compile compile/64/tests/find
-maxdepth 0 -printf '[%h][%f]n'
[.][.]
[.][..]
[][/]
[][tmp]
[/tmp][TRACE]
[.][compile]
[compile/64/tests][find]
