NAME

Linux::ACL - Perl extension for reading and setting Access Control Lists for files by libacl linux library.

VERSION

Version 0.05

SYNOPSIS

Quick summary of what the module does.

Perhaps a little code snippet.

  use Linux::ACL;
  ($acl, $default_acl) = getfacl("path/to/file");
  setfacl("path/to/file", $acl [, $default_acl]);

EXPORT

setfacl($$;$)

Set the ACL of the file or directory named by $path to that specified by $acl. If $path names a directory, then the optional $default_acl argument can also be passed to specify the default ACL for the directory. See "ACL structure" for information on how the $acl and $default_acl hashes should be constructed.

getfacl($)

Return a reference to a hash containing information about the file's ACL. If the file is a directory with a default ACL, then a list is returned, with the first entry being a hash reference to the ACL, and the second being a hash reference to the default ACL. See "Accessing ACL structures" for information on how to access these hashes, and "ACL structure" for information on how these hashes are internally constructed.

RETURN VALUES

setfacl

returns TRUE if successful and FALSE if unsuccessful.

getfacl

if successful, returns a list containing a reference to the hash describing an acl, and, if there is a default acl, a reference to the hash describing the default acl. If unsuccessful, getfacl returns a null list.

Examples

getfacl example

  use Linux::ACL;
  use Data::Dumper;
  my @a = getfacl("/tmp");
  print Dumper \@a;

prints:

  $VAR1 = [
          {
            'uperm' => {
                         'w' => 1,
                         'r' => 1,
                         'x' => 1
                       },
            'gperm' => {
                         'w' => 1,
                         'r' => 1,
                         'x' => 1
                       },
            'other' => {
                         'w' => 1,
                         'r' => 1,
                         'x' => 1
                       }
          }
        ];

setfacl example

  use Linux::ACL;
  setfacl("/mnt/testacl/d", {
        uperm=>{r=>1,w=>1,x=>1},
        gperm=>{r=>1,w=>1,x=>1},
        other=>{r=>1,w=>0,x=>1},
        mask=>{r=>1,w=>1,x=>1},
        group=>{
                123456=>{r=>1,w=>1,x=>1}
        }
  }, {
        uperm=>{r=>1,w=>1,x=>1},
        gperm=>{r=>1,w=>1,x=>1},
        other=>{r=>1,w=>1,x=>1},
        mask=>{r=>1,w=>1,x=>1}
  });
  system("getfacl /mnt/testacl/d");

prints:

  $ getfacl d
  # file: d
  # owner: user
  # group: user
  user::rwx
  group::rwx
  group:123456:rwx
  mask::rwx
  other::r-x
  default:user::rwx
  default:group::rwx
  default:mask::rwx
  default:other::rwx
