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

9 use File::stat;
10 $st = stat($file) or die "No $file: $!";
11 if ( ($st->mode & 0111) && $st->nlink > 1) ) {
12 print "$file is executable with lotsa links\n";
13 }
14
15 use File::stat qw(:FIELDS);
16 stat($file) or die "No $file: $!";
17 if ( ($st_mode & 0111) && ($st_nlink > 1) ) {
18 print "$file is executable with lotsa links\n";
19 }

22 This module's default exports override the core stat() and lstat()
23 functions, replacing them with versions that return "File::stat"
24 objects. This object has methods that return the similarly named
25 structure field name from the stat(2) function; namely, dev, ino, mode,
26 nlink, uid, gid, rdev, size, atime, mtime, ctime, blksize, and blocks.
27
28 You may also import all the structure fields directly into your
29 namespace as regular variables using the :FIELDS import tag. (Note
30 that this still overrides your stat() and lstat() functions.) Access
31 these fields as variables named with a preceding "st_" in front their
32 method names. Thus, "$stat_obj->dev()" corresponds to $st_dev if you
33 import the fields.
34
35 To access this functionality without the core overrides, pass the "use"
36 an empty import list, and then access function functions with their
37 full qualified names. On the other hand, the built-ins are still
38 available via the "CORE::" pseudo-package.
39
41 As of Perl 5.8.0 after using this module you cannot use the implicit $_
42 or the special filehandle "_" with stat() or lstat(), trying to do so
43 leads into strange errors. The workaround is for $_ to be explicit
44
45 my $stat_obj = stat $_;
46
47 and for "_" to explicitly populate the object using the unexported and
48 undocumented populate() function with CORE::stat():
49
50 my $stat_obj = File::stat::populate(CORE::stat(_));
51
53 While this class is currently implemented using the Class::Struct
54 module to build a struct-like class, you shouldn't rely upon this.
