STAT(1)                      BSD Reference Manual                      STAT(1)


     stat - display file status


     stat [-FLnq] [-f format | -l | -r | -s | -x] [-t timefmt] [file ...]


     The stat utility displays information about the file pointed to by file.
     Read, write, or execute permissions of the named file are not required,
     but all directories listed in the path name leading to the file must be
     searchable. If no argument is given, stat displays information about the
     file descriptor for standard input.

     The information displayed is obtained by calling lstat(2) with the given
     argument and evaluating the returned structure.

     The options are as follows:

     -F            As in ls, display a slash ('/') immediately after each
                   pathname that is a directory, an asterisk ('*') after each
                   that is executable, an at sign ('@') after each symbolic
                   link, a percent sign ('%') after each whiteout, an equal
                   sign ('=') after each socket, and a vertical bar ('|')
                   after each that is a FIFO. The use of -F implies -l.

     -f format     Display information using the specified format. See the
                   FORMATS section for a description of valid formats.

     -L            Use stat(2) instead of lstat(2). The information reported
                   by stat will refer to the target of file, if file is a sym-
                   bolic link, and not to file itself.

     -l            Display output in ls -lT format.

     -n            Do not force a newline to appear at the end of each piece
                   of output.

     -q            Suppress failure messages if calls to stat(2) or lstat(2)

     -r            Display raw information. That is, for all the fields in the
                   stat-structure, display the raw, numerical value (for exam-
                   ple, times in seconds since the epoch, etc.)

     -s            Display information in "shell output", suitable for ini-
                   tializing variables.

     -t timefmt    Display timestamps using the specified format. This format
                   is passed directly to strftime(3).

     -x            Display information in a more verbose way as known from
                   some Linux distributions.


     Format strings are similar to printf(3) formats in that they start with
     %, are then followed by a sequence of formatting characters, and end in a
     character that selects the field of the struct stat which is to be for-
     matted. If the % if immediately followed by a slash ('/') and two hexade-
     cimal digits, the corresponding octet is output; if it is immediately
     followed by one of n, t, %, or @, then a newline character, a tab charac-
     ter, a percent character, or the current file number is printed, other-
     wise the string is examined for the following:

     Any of the following optional flags:

     #       Selects an alternate output form for octal and hexadecimal out-
             put. Non-zero octal output will have a leading zero, and non-zero
             hexadecimal output will have "0x" prepended to it.

     +       Asserts that a sign indicating whether a number is positive or
             negative should always be printed. Non-negative numbers are not
             usually printed with a sign.

     -       Aligns string output to the left of the field, instead of to the

     0       Sets the fill character for left padding to the 0 character, in-
             stead of a space.

     space   Reserves a space at the front of non-negative signed output
             fields. A '+' overrides a space if both are used.

     Then the following fields:

     size    An optional decimal digit string specifying the minimum field

     prec    An optional precision composed of a decimal point '.' and a de-
             cimal digit string that indicates the maximum string length, the
             number of digits to appear after the decimal point in floating
             point output, or the minimum number of digits to appear in numer-
             ic output.

     fmt     An optional output format specifier which is one of D, O, U, X,
             F, or S. These represent signed decimal output, octal output, un-
             signed decimal output, hexadecimal output, floating point output,
             and string output, respectively. Some output formats do not apply
             to all fields. Floating point output only applies to timespec
             fields (the a, m, and c fields).

             The special output specifier S may be used to indicate that the
             output, if applicable, should be in string format. May be used in
             combination with

             amc     Display date in strftime(3) format.

             dr      Display actual device name.

             gu      Display group or user name.

             p       Display the mode of file as in ls -lTd.

             N       Displays the name of file.

             T       Displays the type of file.

             Y       Insert a `` -> '' into the output. Note that the default
                     output format for Y is a string, but if specified expli-
                     citly, these four characters are prepended.

     sub     An optional sub field specifier (high, middle, low). Only applies
             to the p, d, r, and T output formats. It can be one of the fol-

             H       "High" -- specifies the major number for devices from r
                     or d, the "user" bits for permissions from the string
                     form of p, the file "type" bits from the numeric forms of
                     p, the long output form of T, and the directory path from
                     the N output similar to what dirname(1) would show.

             L       "Low" -- specifies the minor number for devices from r or
                     d, the "other" bits for permissions from the string form
                     of p, the nanosecond part of the timestamp for a, m, c,
                     B, the "user", "group", and "other" bits from the numeric
                     forms of p, the ls -F style output character for file
                     type when used with T (the use of L for this is option-
                     al), and the filename component of the N output form
                     similar to what basename(1) would display.

             M       "Middle" -- specifies the "group" bits for permissions
                     from the string output form of p, or the "suid", "sgid",
                     and "sticky" bits for the numeric forms of p.

     datum   A required field specifier, being one of the following:

             d    Device upon which file resides.

             i    files inode number.

             p    File type and permissions.

             l    Number of hard links to file.

             u, g
                  User-id and group-id of files owner.

             r    Device number for character and block device special files.

             a, m, c, B
                  The time file was last accessed or modified, of when the
                  inode was last changed, or the birth time of the inode.

             z    The size of file in bytes.

             b    Number of blocks allocated for file.

             k    Optimal filesystem I/O operation block size.

             f    User defined flags for file.

             v    Inode generation number.

             The following four field specifiers are not drawn directly from
             the data in struct stat, but are

             N       The name of the file.

             T       The file type, either as in ls -F or in a more descrip-
                     tive form if the sub field specifier H is given.

             Y       The target of a symbolic link.

             Z       Expands to "major,minor" from the rdev field for charac-
                     ter or block special devices and gives size output for
                     all others.

     Only the % and the field specifier are required. Most field specifiers
     default to U as an output form, with the exception of p which defaults to
     O, a, m, and c which default to D, and Y, T, and N, which default to S.


     stat exits 0 on success, and >0 if an error occurred.


     If no options are specified, the default format is "%d %i %Sp %l %Su %Sg
     %r %z \"%Sa\" \"%Sm\" \"%Sc\" \"%SB\" %k %b %#Xf %N".

           > stat /tmp/bar
           0 78852 -rw-r--r-- 1 root wheel 0 0 "Jul  8 10:26:03 2004" "Jul  8 10:26:03 2004" "Jul  8 10:28:13 2004" "Jan  1 09:00:00 1970" 16384 0 0 /tmp/bar

     Given a symbolic link "foo" that points from /tmp/foo to /, you would use
     stat as follows:

           > stat -F /tmp/foo
           lrwxrwxrwx 1 jschauma cs 1 Apr 24 16:37:28 2002 /tmp/foo@ -> /

           > stat -LF /tmp/foo
           drwxr-xr-x 16 root wheel 512 Apr 19 10:57:54 2002 /tmp/foo/

     To initialize some shell-variables, you could use the -s flag as follows:

           > csh
           % eval set `stat -s .cshrc`
           % echo $st_size $st_mtime
           1148 1015432481

           > sh
           $ eval $(stat -s .profile)
           $ echo $st_size $st_mtime
           1148 1015432481

     In order to get a list of the kind of files including files pointed to if
     the file is a symbolic link, you could use the following format:

           $ stat -f "%N: %HT%SY" /tmp/*
           /tmp/bar: Symbolic Link -> /tmp/foo
           /tmp/output25568: Regular File
           /tmp/blah: Directory
           /tmp/foo: Symbolic Link -> /

     In order to get a list of the devices, their types and the major and
     minor device numbers, formatted with tabs and linebreaks, you could use
     the following format:

           stat -f "Name: %N%n%tType: %HT%n%tMajor: %Hr%n%tMinor: %Lr%n%n" /dev/*
           Name: /dev/wt8
                   Type: Block Device
                   Major: 3
                   Minor: 8

           Name: /dev/zero
                   Type: Character Device
                   Major: 2
                   Minor: 12

     In order to determine the permissions set on a file separately, you could
     use the following format:

           > stat -f "%Sp -> owner=%SHp group=%SMp other=%SLp" .
           drwxr-xr-x -> owner=rwx group=r-x other=r-x

     In order to determine the three files that have been modified most re-
     cently, you could use the following format:

           > stat -f "%m%t%Sm %N" /tmp/* | sort -rn | head -3 | cut -f2-
           Apr 25 11:47:00 2002 /tmp/blah
           Apr 25 10:36:34 2002 /tmp/bar
           Apr 24 16:47:35 2002 /tmp/foo


     file(1), basename(1), dirname(1), ls(1), lstat(2), readlink(1),
     readlink(2), stat(2), printf(3), strftime(3)


     The stat utility appeared in NetBSD 1.6 and was ported to MirBSD #8. The
     "%/00" output format specifier was added in MirBSD #11.


     The stat utility was written by Andrew Brown <atatat@NetBSD.org>. This
     man page was written by Jan Schaumann <jschauma@NetBSD.org>.
