file status

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 pathname 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 default format displays the st_dev, st_ino, st_mode, st_nlink, st_uid, st_gid, st_rdev, st_size, st_atime, st_mtime, st_ctime, st_blksize, st_blocks, and st_flags fields, in that order.
The options are as follows:
-F
-F
implies
-l
.-f
format-L
stat
will refer to the target of
file, if file is a symbolic link, and not to
file itself.-l
ls
-lT
format.-n
-q
-r
-s
-t
timefmt-x
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 formatted. If the %
is immediately
followed by one of n
, t
,
%
, or @
, then a newline
character, a tab character, a percent character, or the current file number
is printed, otherwise the string is examined for the following:
Any of the following optional flags:
#
+
-
0
+
’ overrides a space if both are
used.Then the following fields:
size
prec
.
’ and a decimal 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 numeric output.fmt
D
, O
,
U
, X
,
F
, or S
. These represent
signed decimal output, octal output, unsigned 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
dr
gu
p

Y

string, but if specified explicitly, these four characters are
prepended.sub

output formats.
It can be one of the following:
H
r
or d
, the user bits
for permissions from the string form of p
, the
file type bits from the numeric forms of p
,
and the long output form of T
.L
r
or d
, the other bits
for permissions from the string form of p
, the
user, group, and other bits from the numeric forms of
p
, and the ls -F
style
output character for file type when used with
T
(the use of L
for
this is optional).M

The following four field specifiers are not drawn directly from the data in struct stat, but are:
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
.
The stat
utility exits 0 on
success, and >0 if an error occurs.
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/xfs0 Type: Character Device Major: 51 Minor: 0 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 recently, 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

A stat
utility first appeared in
Version 1 AT&T UNIX but disappeared after
Version 4 AT&T UNIX. It reappeared in
NetBSD 1.6 and has been available since
OpenBSD 3.8.
The stat
utility was written by
Andrew Brown
