.Sh DESCRIPTION
|
||||||
|
The
|
||||||
|
.Nm
|
||||||
|
utility displays information about the file pointed to by
|
||||||
|
.Ar 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,
|
||||||
|
.Nm
|
||||||
|
displays information about the file descriptor for standard input.
|
||||||
|
.Pp
|
||||||
|
The information displayed is obtained by calling
|
||||||
|
.Xr lstat 2
|
||||||
|
with the given argument and evaluating the returned structure.
|
||||||
|
.Pp
|
||||||
|
The options are as follows:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Fl F
|
||||||
|
As in
|
||||||
|
.Ic 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
|
||||||
|
.Fl F
|
||||||
|
implies
|
||||||
|
.Fl l .
|
||||||
|
.It Fl L
|
||||||
|
Use
|
||||||
|
.Xr stat 2
|
||||||
|
instead of
|
||||||
|
.Xr lstat 2 .
|
||||||
|
The information reported by
|
||||||
|
.Nm
|
||||||
|
will refer to the target of
|
||||||
|
.Ar file ,
|
||||||
|
if file is a symbolic link, and not to
|
||||||
|
.Ar file
|
||||||
|
itself.
|
||||||
|
.It Fl n
|
||||||
|
Do not force a newline to appear at the end of each piece of output.
|
||||||
|
.It Fl f Ar format
|
||||||
|
Display information using the specified format. See the FORMATS section
|
||||||
|
for a description of valid formats.
|
||||||
|
.It Fl l
|
||||||
|
Display output in
|
||||||
|
.Ic ls Fl lT
|
||||||
|
format.
|
||||||
|
.It Fl r
|
||||||
|
Display raw information. That is, for all the fields in the stat-structure,
|
||||||
|
display the raw, numerical value (for example, times in seconds since the
|
||||||
|
epoch, etc.)
|
||||||
|
.It Fl s
|
||||||
|
Display information in ``shell output'', suitable for initializing variables.
|
||||||
|
.It Fl x
|
||||||
|
Display information in a more verbose way as known from some Linux
|
||||||
|
distributions.
|
||||||
|
.It Fl t Ar timefmt
|
||||||
|
Display timestamps using the specified format. This format is
|
||||||
|
passed directly to
|
||||||
|
.Xr strftime 3 .
|
||||||
|
.El
|
||||||
|
.Ss FORMATS
|
||||||
|
Format strings are similar to
|
||||||
|
.Xr printf 3
|
||||||
|
formats in that they start with
|
||||||
|
.Cm % ,
|
||||||
|
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
|
||||||
|
.Cm %
|
||||||
|
is immediately followed by one of
|
||||||
|
.Cm n ,
|
||||||
|
.Cm t ,
|
||||||
|
.Cm % ,
|
||||||
|
or
|
||||||
|
.Cm @ ,
|
||||||
|
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:
|
||||||
|
.Pp
|
||||||
|
Any of the following optional flags:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Cm #
|
||||||
|
Selects an alternate output form for octal and hexadecimal output.
|
||||||
|
Non-zero octal output will have a leading zero, and non-zero
|
||||||
|
hexadecimal output will have ``0x'' prepended to it.
|
||||||
|
.It Cm +
|
||||||
|
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.
|
||||||
|
.It Cm -
|
||||||
|
Aligns string output to the left of the field, instead of to the right.
|
||||||
|
.It Cm 0
|
||||||
|
Sets the fill character for left padding to the 0 character, instead of
|
||||||
|
a space.
|
||||||
|
.It space
|
||||||
|
Reserves a space at the front of non-negative signed output fields. A
|
||||||
|
.Sq Cm +
|
||||||
|
overrides a space if both are used.
|
||||||
|
.El
|
||||||
|
.Pp
|
||||||
|
Then the following fields:
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Cm size
|
||||||
|
An optional decimal digit string specifying the minimum field width.
|
||||||
|
.It Cm prec
|
||||||
|
An optional precision composed of a decimal point
|
||||||
|
.Sq Cm \&.
|
||||||
|
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.
|
||||||
|
.It Cm fmt
|
||||||
|
An optional output format specifier which is one of
|
||||||
|
.Cm D ,
|
||||||
|
.Cm O ,
|
||||||
|
.Cm U ,
|
||||||
|
.Cm X ,
|
||||||
|
.Cm F ,
|
||||||
|
or
|
||||||
|
.Cm 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
|
||||||
|
.Cm a ,
|
||||||
|
.Cm m ,
|
||||||
|
and
|
||||||
|
.Cm c
|
||||||
|
fields).
|
||||||
|
.Pp
|
||||||
|
The special output specifier
|
||||||
|
.Cm S
|
||||||
|
may be used to indicate that the output, if
|
||||||
|
applicable, should be in string format. May be used in combination with
|
||||||
|
.Bl -tag -width Ds
|
||||||
|
.It Cm amc
|
||||||
|
Display date in strftime(3) format.
|

||||||
|
.It Cm N
|
||||||
|
Displays the name of
|
||||||
|
.Ar file .
|
||||||
|
.It Cm T
|
||||||
|
Displays the type of
|
||||||
|
.Ar file .
|
||||||
|
.It Cm Y
|
||||||
|
Insert a `` -\*[Gt] '' into the output. Note that the default output format
|
||||||
|
for
|
||||||
|
.Cm Y
|
||||||
|
is a string, but if specified explicitly, these four characters are
|
||||||
|
prepended.
|
||||||
|
.El
|
||||||
|
.It Cm sub

|
||||||

|
||||||
|

||||||
|
exits 0 on success, and \*[Gt]0 if an error occurred.
|
||||||
|
.Sh EXAMPLES
|
||||||
|
Given a symbolic link ``foo'' that points from /tmp/foo to /, you would use
|
||||||
|
.Nm
|
||||||
|
as follows:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
\*[Gt] stat -F /tmp/foo
|
||||||
|
lrwxrwxrwx 1 jschauma cs 1 Apr 24 16:37:28 2002 /tmp/foo@ -\*[Gt] /
|
||||||
|
|
||||||
|
\*[Gt] stat -LF /tmp/foo
|
||||||
|
lrwxrwxrwx 16 root wheel 512 Apr 19 10:57:54 2002 /tmp/foo/
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
To initialize some shell-variables, you could use the
|
||||||
|
.Fl s
|
||||||
|
flag as follows:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
\*[Gt] csh
|
||||||
|
% eval set `stat -s .cshrc`
|
||||||
|
% echo $st_size $st_mtimespec
|
||||||
|
1148 1015432481
|
||||||
|
|
||||||
|
\*[Gt] sh
|
||||||
|
$ eval $(stat -s .profile)
|
||||||
|
$ echo $st_size $st_mtimespec
|
||||||
|
1148 1015432481
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
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:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
$ stat -f "%N: %HT%SY" /tmp/*
|
||||||
|
/tmp/bar: Symbolic Link -\*[Gt] /tmp/foo
|
||||||
|
/tmp/output25568: Regular File
|
||||||
|
/tmp/blah: Directory
|
||||||
|
/tmp/foo: Symbolic Link -\*[Gt] /
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
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:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
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
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
In order to determine the permissions set on a file separately, you could use
|
||||||
|
the following format:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
\*[Gt] stat -f "%Sp -\*[Gt] owner=%SHp group=%SMp other=%SLp" .
|
||||||
|
drwxr-xr-x -\*[Gt] owner=rwx group=r-x other=r-x
|
||||||
|
.Ed
|
||||||
|
.Pp
|
||||||
|
In order to determine the three files that have been modified most recently,
|
||||||
|
you could use the following format:
|
||||||
|
.Bd -literal -offset indent
|
||||||
|
\*[Gt] stat -f "%m%t%Sm %N" /tmp/* | sort -rn | head -3 | cut -f2-
