/* stat.c Feb 1987 - main, printit, statit
*
* stat - a program to perform what the stat(2) call does.
*
* usage: stat [-] [-all] -<field> [-<field> ...] [file1 file2 file3 ...]
*
* where <field> is one of the struct stat fields without the leading "st_".
* The three times can be printed out as human times by requesting
* -Ctime instead of -ctime (upper case 1st letter).
* - means take the file names from stdin.
* -0.. means fd0..
* no files means all fds.
*
* output: if only one field is specified, that fields' contents are printed.
* if more than one field is specified, the output is
* file filed1: f1val, field2: f2val, etc
*
* written: Larry McVoy, (mcvoy@rsch.wisc.edu)

.TH STAT 1
.SH NAME
stat, lstat, readlink \- provide a shell interface to the stat(2) system call
.SH SYNOPSIS
.B stat
.RB [ - ]
.RB [ -\fIfd ]
.RB [ -all ]
.RB [ -s ]
.RB [ -\fIfield " ...]"
.RI [ file1 " ...]"
.SH DESCRIPTION
.B Stat
does little more than provide access to the fields in the
.B struct stat
as defined in the
.BR stat (2)
manual page. Each field that is to be listed
is specified as the field name without the leading
.BR st_ .
This and the other two options are described below. All options are then
applied to the files listed. If
.B stat
is called as
.B lstat
then the
.BR lstat (2)
system call is used, if called as
.B stat
symbolic links are expanded with
.BR stat (2).
If called as
.B readlink
then the output is only the contents of the symbolic link.
.PP
If no fields are named then all fields are printed. If no files are listed
then all open filedescriptors are printed.
.SH OPTIONS
.TP
.B \-
If the first argument is ``\-'', the list of files is assumed to come from stdin.
This is useful for things like ``ls | stat \-uid \-mtime.''
.B \-\fIfd
If an argument is a ``\-'' followed by a number then that number is used as
a file descriptor whose information is to be printed.
.TP
.B \-all
List all fields for each file.
.TP
.B \-s
Use
.BR lstat (2).
.TP
.B \-mode
List the
.B mode
field. Similarly for
.BR ino ,
.BR dev ,
.BR rdev ,
.BR nlink ,
.BR uid ,
.BR gid ,
.BR size ,
.BR atime ,
.BR mtime ,
and
.BR ctime .
Under BSD derived systems you also have
.B blksize
and
.BR blocks .
.PP
.B \-Atime
.br
.B \-Mtime
.br
.B \-Ctime
.RS
The lower case versions of these three options display the time as an integer
that is the ``seconds since 00:00 Jan 1. 1970.''
Listing the fields with the first letter
in caps causes the times to be printed in
.BR ctime (3)
format (i.e., human readable).
.RE
.SH EXAMPLES
.LP
# Find out the number of links to each file
.br
$ stat \-nlink *.c
.LP
# sort files by age (much like ls \-t)
.br
$ stat \-atime * | sort +1
.LP
# Find out which file is older in sh(1)
.br
if test `stat -mtime $1` -lt `stat -mtime $2`; then
.br
echo $1 is older than $2
.br
else
.br
echo $2 is older than $1
.br
fi
.SH "SEE ALSO"
.BR stat (2).

.Sh NAME
.Nm stat ,
.Nm readlink
.Nd display file status
.Sh SYNOPSIS
.Nm
.Op Fl FLnq
.Oo
.Fl f Ar format |
.Fl l |
.Fl r |
.Fl s |
.Fl x
.Oc
.Op Fl t Ar timefmt
.Op Ar
.Nm readlink
.Op Fl fn
.Op Ar
.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 pathname leading to the file must be
searchable.
If no argument is given,
.Nm
displays information about the file descriptor for standard input.
.Pp
When invoked as
.Nm readlink ,
only the target of the symbolic link is printed.
If the given argument is not a symbolic link and the
.Fl f
option is not specified,
.Nm readlink
will print nothing and exit with an error.
If the
.Fl f
option is specified, the output is canonicalized by following every symlink
in every component of the given path recursively.
.Nm readlink
will resolve both absolute and relative paths, and return the absolute pathname
corresponding to
.Ar file .
In this case, the argument does not need to be a symbolic link.
.Pp
The information displayed is obtained by calling
.Xr lstat 2
with the given argument and evaluating the returned structure.
The default format displays the
.Fa st_dev ,
.Fa st_ino ,
.Fa st_mode ,
.Fa st_nlink ,
.Fa st_uid ,
.Fa st_gid ,
.Fa st_rdev ,
.Fa st_size ,
.Fa st_atime ,
.Fa st_mtime ,
.Fa st_ctime ,
.Fa st_birthtime ,
.Fa st_blksize ,
.Fa st_blocks ,
and
.Fa st_flags
fields, in that order.
.Pp
The options are as follows:
.Bl -tag -width XFXformatXXX
.It Fl F
As in
.Xr ls 1 ,
display a slash
.Pq Sq /
immediately after each pathname that is a directory, an
asterisk
.Pq Sq *
after each that is executable, an at sign
.Pq Sq @
after each symbolic link, a percent sign
.Pq Sq %
after each whiteout, an equal sign
.Pq Sq =
after each socket, and a vertical bar
.Pq Sq \&|
after each that is a FIFO.
The use of
.Fl F
implies
.Fl l .
.It Fl f Ar format
Display information using the specified format.
See the
.Sx FORMATS
section for a description of valid formats.
.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 l
Display output in
.Ic ls Fl lT
format.
.It Fl n
Do not force a newline to appear at the end of each piece of output.
.It Fl q
Suppress failure messages if calls to
.Xr stat 2
or
.Xr lstat 2
fail.
When run as
.Nm readlink ,
error messages are automatically suppressed.
.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
.Dq shell output ,
suitable for initializing variables.
.It Fl t Ar timefmt
Display timestamps using the specified format.
This format is
passed directly to
.Xr strftime 3 .
.It Fl x
Display information in a more verbose way as known from some Linux
distributions.
.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
.Dq 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 dr
Display actual device name.
.It Cm gu

.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
An optional sub field specifier (high, middle, or low).
Only applies to the
.Cm p ,
.Cm d ,
.Cm r ,
.Cm T ,
.Cm N ,
and
.Cm z

The following five field specifiers are not drawn directly from the
data in struct stat, but are:
.Bl -tag -width Ds
.It Cm N
The name of the file.
.It Cm R
The absolute pathname corresponding to the file.
.It Cm T
The file type, either as in
.Ic ls -F
or in a more descriptive form if the sub field specifier
.Cm H
is given.
.It Cm Y
The target of a symbolic link.
.It Cm Z
Expands to
.Dq major,minor
from the rdev field for character or block
special devices and gives size output for all others.
.El
.El
.Pp
Only the
.Cm %
and the field specifier are required.
Most field specifiers default to
.Cm U
as an output form, with the
exception of
.Cm p
which defaults to
.Cm O ;
.Cm a , m ,
and
.Cm c
which default to
.Cm D ;
and
.Cm Y , T ,
and
.Cm N ,
which default to
.Cm S .
.Sh EXIT STATUS
.Nm
exits 0 on success, and \*[Gt]0 if an error occurred.
.Sh EXAMPLES
If no options are specified, the default format is
"%d %i %Sp %l %Su %Sg %r %z \e"%Sa\e" \e"%Sm\e" \e"%Sc\e" \e"%SB\e" %k %b %#Xf %N".

Given a symbolic link
.Dq foo
that points from
.Pa /tmp/foo
to
.Pa / ,
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
drwxr-xr-x 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_mtime
1148 1015432481
\*[Gt] 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:
.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] /

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

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

.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-
Apr 25 11:47:00 2002 /tmp/blah
