NAME
    find - search for files in a directory hierarchy

SYNOPSIS
    find [path...] [expression]

DESCRIPTION
    This manual page documents the GNU version of find. find searches the
    directory tree rooted at each given file name by evaluating the  given
    expression from  left to right, according to the rules of precedence
    (see section OPERATORS), until the outcome is known (the left hand side
    is false for and operations, true for or), at which point find moves on
    to the next file name.

    The first argument that begins with `-', `(', `)', `,', or `!' is taken
    to be the beginning of the expression; any arguments before it are
    paths to search, and any arguments after it are the rest of the expres-
    sion.  If no paths are given, the current directory is used.  If no
    expression is given, the expression `-print' is used.

    find exits with status 0  if all files  are processed  successfully,
    greater than 0 if errors occur.

EXPRESSIONS
    The expression is made up of options (which affect overall operation
    rather than the processing of a specific file, and always return true),
    tests (which return a  true or false value), and actions (which have
    side effects and return a true or false value), all separated by opera-
    tors.  -and is assumed where the operator is omitted. If the expres-
    sion contains no actions other than -prune, -print is performed on all
    files for which the expression is true.

 OPTIONS
    All options always return true. They always take effect, rather than
    being processed only when their place in  the expression is reached.
    Therefore, for clarity, it is best to place them at the beginning of
    the expression.

    -daystart
    Measure times (for -amin,  -atime, -cmin, -ctime, -mmin, and
    -mtime) from the beginning of today rather than from 24 hours
    ago.

    -depth Process each directory's contents before the directory itself.

    -follow
    Dereference symbolic links. Implies -noleaf.

    -help, --help
    Print a summary of the command-line usage of find and exit.

    -maxdepth levels
    Descend at most levels (a non-negative integer) levels of direc-
    tories below the command line arguments. `-maxdepth 0' means
    only apply the tests and actions to the command line arguments.

    -mindepth levels
    Do not apply any tests or actions at levels less than levels (a
    non-negative integer). `-mindepth 1' means process all  files
    except the command line arguments.

    -mount Don't descend directories on other filesystems. An alternate
    name for -xdev, for compatibility with some other versions of
    find.

    -noleaf
    Do not optimize  by assuming that directories contain 2 fewer
    subdirectories than their  hard link count.  This option is
    needed when searching filesystems that do not follow the Unix
    directory-link convention, such as CD-ROM or MS-DOS filesystems
    or AFS volume mount points. Each directory on a normal Unix
    filesystem has at least 2 hard links: its name  and its `.'
    entry.  Additionally, its subdirectories (if any) each have a
    `..' entry linked to that directory. When find is examining a
    directory, after it has statted 2 fewer subdirectories than the
    directory's link count, it knows that the rest of the entries in
    the directory are non-directories (`leaf' files in the directory
    tree). If only the files' names need to be examined, there is
    no need to stat them;  this gives a significant increase in
    search speed.

    -version, --version
    Print the find version number and exit.

    -xdev Don't descend directories on other filesystems.

 TESTS
    Numeric arguments can be specified as

    +n   for greater than n,

    -n   for less than n,

    n   for exactly n.

    -amin n
    File was last accessed n minutes ago.

    -anewer file
    File was last accessed more recently than file was modified.
    -anewer is affected by  -follow only if -follow comes before
    -anewer on the command line.

    -atime n
    File was last accessed n*24 hours ago.

    -cmin n
    File's status was last changed n minutes ago.

    -cnewer file
    File's status was last changed more recently than file was modi-
    fied.  -cnewer is affected by  -follow only if -follow comes
    before -cnewer on the command line.

    -ctime n
    File's status was last changed n*24 hours ago.

    -empty File is empty and is either a regular file or a directory.

    -false Always false.

    -fstype type
    File is on a filesystem of type type. The valid filesystem
    types vary among different versions of Unix; an incomplete list
    of filesystem types that are accepted on some version of Unix or
    another is: ufs, 4.2, 4.3, nfs, tmp, mfs, S51K, S52K. You can
    use -printf with the %F directive  to see the types of your
    filesystems.

    -gid n File's numeric group ID is n.

    -group gname
    File belongs to group gname (numeric group ID allowed).

    -ilname pattern
    Like -lname, but the match is case insensitive.

    -iname pattern
    Like -name, but the match is case insensitive. For example, the
    patterns `fo*' and `F??' match the file  names `Foo', `FOO',
    `foo', `fOo', etc.

    -inum n
    File has inode number n.

    -ipath pattern
    Like -path, but the match is case insensitive.

    -iregex pattern
    Like -regex, but the match is case insensitive.

    -links n
    File has n links.

    -lname pattern
    File is a symbolic link whose contents match shell pattern pat-
    tern. The metacharacters do not treat `/' or `.' specially.

    -mmin n
    File's data was last modified n minutes ago.

    -mtime n
    File's data was last modified n*24 hours ago.

    -name pattern
    Base of file name (the  path with the leading directories
    removed) matches  shell pattern  pattern.  The metacharacters
    (`*', `?', and `[]') do not match a `.' at the start of the base
    name. To ignore a directory and the files under it, use -prune;
    see an example in the description of -path.

    -newer file
    File was modified more recently than file. -newer is affected
    by -follow only  if -follow comes before -newer on the command
    line.

    -nouser
    No user corresponds to file's numeric user ID.

    -nogroup
    No group corresponds to file's numeric group ID.

    -path pattern
    File name matches shell pattern pattern. The metacharacters do
    not treat `/' or `.' specially; so, for example,
   find . -path './sr*sc'
    will print an entry for a directory called './src/misc' (if one
    exists). To ignore a whole directory tree, use -prune rather
    than checking every file in the tree. For example, to skip the
    directory `src/emacs' and all files and directories under it,
    and print the names of the other files found, do something like
    this:
   find . -path './src/emacs' -prune -o -print

    -perm mode
    File's permission bits are exactly mode (octal or symbolic).
    Symbolic modes use mode 0 as a point of departure.

    -perm -mode
    All of the permission bits mode are set for the file.

    -perm +mode
    Any of the permission bits mode are set for the file.

    -regex pattern
    File name matches regular expression pattern. This is a match
    on the whole path, not a search. For example, to match a file
    named `./fubar3', you can use the regular expression `.*bar.' or
    `.*b.*3', but not `b.*r3'.

    -size n[bckw]
    File uses n units of space. The units are 512-byte blocks by
    default or if `b' follows n, bytes if `c' follows n, kilobytes
    if `k' follows n, or 2-byte words if `w' follows n.  The size
    does not  count indirect blocks, but it does count blocks in
    sparse files that are not actually allocated.

    -true Always true.

    -type c
    File is of type c:

    b    block (buffered) special

    c    character (unbuffered) special

    d    directory

    p    named pipe (FIFO)

    f    regular file

    l    symbolic link

    s    socket

    D    door (Solaris)

    -uid n File's numeric user ID is n.

    -used n
    File was last accessed n days after its status was last changed.

    -user uname
    File is owned by user uname (numeric user ID allowed).

    -xtype c
    The same as -type unless the file is a symbolic link. For sym-
    bolic links: if -follow has not been given, true if the file is
    a link to a file of type c; if -follow has been given, true if c
    is `l'. In other words, for symbolic links, -xtype checks the
    type of the file that -type does not check.

 ACTIONS
    -exec command ;
    Execute command;  true if 0 status is returned.  All following
    arguments to find are taken to be arguments to the command until
    an argument consisting of `;' is encountered. The string `{}'
    is replaced by the current file name being processed everywhere
    it occurs in the arguments to the command, not just in arguments
    where it is alone, as in some versions of find. Both of  these
    constructions might need to be escaped (with a `\') or quoted to
    protect them from expansion by the shell.  The command is exe-
    cuted in the starting directory.

    -fls file
    True; like -ls but write to file like -fprint.

    -fprint file
    True; print the full file name into file file. If file does not
    exist when find is run, it is created; if it does exist, it is
    truncated.  The file names ``/dev/stdout'' and ``/dev/stderr''
    are handled specially; they refer to the  standard output and
    standard error output, respectively.

    -fprint0 file
    True; like -print0 but write to file like -fprint.

    -fprintf file format
    True; like -printf but write to file like -fprint.

    -ok command ;
    Like -exec but ask the user first (on the standard input); if
    the response does not start with `y' or `Y', do not run the com-
    mand, and return false.

    -print True; print the full file name on the standard output, followed
    by a newline.

    -print0
    True; print the full file name on the standard output, followed
    by a null character. This allows file names that contain new-
    lines to be correctly interpreted by programs that process the
    find output.

    -printf format
    True; print format on the standard output, interpreting `\'
    escapes and `%' directives. Field widths and precisions can be
    specified  as with the `printf' C function. Unlike -print,
    -printf does not add a newline at the end of the  string.  The
    escapes and directives are:

    \a   Alarm bell.

    \b   Backspace.

    \c   Stop printing from this format immediately and flush the
     output.

    \f   Form feed.

    \n   Newline.

    \r   Carriage return.

    \t   Horizontal tab.

    \v   Vertical tab.

    \\   A literal backslash (`\').

    \NNN  The character whose ASCII code is NNN (octal).

    A `\' character followed by any other character is treated as an
    ordinary character, so they both are printed.

    %%   A literal percent sign.

    %a   File's last access time in the format returned by the C
     `ctime' function.

    %Ak  File's last access time in the format specified by k,
     which is either `@' or a directive for the C `strftime'
     function. The possible values for k are listed below;
     some of them might not be available on all systems, due
     to differences in `strftime' between systems.
