File::stat(3)	       Perl Programmers	Reference Guide		 File::stat(3)

       File::stat - by-name interface to Perl's	built-in stat()	functions

	use File::stat;
	$st = stat($file) or die "No $file: $!";
	if ( ($st->mode	& 0111)	&& $st->nlink >	1) ) {
	    print "$file is executable with lotsa links\n";

	if ( -x	$st ) {
	    print "$file is executable\n";

	use Fcntl "S_IRUSR";
	if ( $st->cando(S_IRUSR, 1) ) {
	    print "My effective	uid can	read $file\n";

	use File::stat qw(:FIELDS);
	stat($file) or die "No $file: $!";
	if ( ($st_mode & 0111) && ($st_nlink > 1) ) {
	    print "$file is executable with lotsa links\n";

       This module's default exports override the core stat() and lstat()
       functions, replacing them with versions that return "File::stat"
       objects.	 This object has methods that return the similarly named
       structure field name from the stat(2) function; namely, dev, ino, mode,
       nlink, uid, gid,	rdev, size, atime, mtime, ctime, blksize, and blocks.

       As of version 1.02 (provided with perl 5.12) the	object provides	"-X"
       overloading, so you can call filetest operators ("-f", "-x", and	so on)
       on it. It also provides a "->cando" method, called like

	$st->cando( ACCESS, EFFECTIVE )

       where ACCESS is one of "S_IRUSR", "S_IWUSR" or "S_IXUSR"	from the Fcntl
       module, and EFFECTIVE indicates whether to use effective	(true) or real
       (false) ids. The	method interprets the "mode", "uid" and	"gid" fields,
       and returns whether or not the current process would be allowed the
       specified access.

       If you don't want to use	the objects, you may import the	"->cando"
       method into your	namespace as a regular function	called "stat_cando".
       This takes an arrayref containing the return values of "stat" or
       "lstat" as its first argument, and interprets it	for you.

       You may also import all the structure fields directly into your
       namespace as regular variables using the	:FIELDS	import tag.  (Note
       that this still overrides your stat() and lstat() functions.)  Access
       these fields as variables named with a preceding	"st_" in front their
       method names.  Thus, "$stat_obj->dev()" corresponds to $st_dev if you
       import the fields.

       To access this functionality without the	core overrides,	pass the "use"
       an empty	import list, and then access function functions	with their
       full qualified names.  On the other hand, the built-ins are still
       available via the "CORE::" pseudo-package.

       As of Perl 5.8.0	after using this module	you cannot use the implicit $_
       or the special filehandle "_" with stat() or lstat(), trying to do so
       leads into strange errors.  The workaround is for $_ to be explicit

	   my $stat_obj	= stat $_;

       and for "_" to explicitly populate the object using the unexported and
       undocumented populate() function	with CORE::stat():

	   my $stat_obj	= File::stat::populate(CORE::stat(_));

       -%s is not implemented on a File::stat object
	   The filetest	operators "-t",	"-T" and "-B" are not implemented, as
	   they	require	more information than just a stat buffer.

       These can all be	disabled with

	   no warnings "File::stat";

       File::stat ignores use filetest 'access'
	   You have tried to use one of	the "-rwxRWX" filetests	with "use
	   filetest 'access'" in effect. "File::stat" will ignore the pragma,
	   and just use	the information	in the "mode" member as	usual.

       File::stat ignores VMS ACLs
	   VMS systems have a permissions structure that cannot	be completely
	   represented in a stat buffer, and unlike on other systems the
	   builtin filetest operators respect this. The	"File::stat"
	   overloads, however, do not, since the information required is not

       While this class	is currently implemented using the Class::Struct
       module to build a struct-like class, you	shouldn't rely upon this.
