file::stat
File::stat(3pm) Perl Programmers Reference Guide File::stat(3pm)
NAME
File::stat - by-name interface to Perl's built-in stat() functions
SYNOPSIS
use File::stat;
$st = stat($file) or die "No $file: $!";
if ( ($st->mode & 0111) && $st->nlink > 1) ) {
print "$file is executable with lotsa links
";
}
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
";
}
DESCRIPTION
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.
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.
BUGS
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(_));
NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
