=head1 NAME
Linux::ACL - Perl extension for reading and setting Access Control Lists for files by libacl linux library.
=head1 VERSION
Version 0.05
=cut
=head1 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]);
=head1 EXPORT
=over
=item setfacl($$;$)
Set the ACL of the file or directory named by C<$path> to that
specified by C<$acl>. If C<$path> names a directory, then the optional
C<$default_acl> argument can also be passed to specify the default ACL
for the directory. See L<"ACL structure"> for information on how the
C<$acl> and C<$default_acl> hashes should be constructed.
=item getfacl($)
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 L<"Accessing
ACL structures"> for information on how to access these hashes, and
L<"ACL structure"> for information on how these hashes are internally
constructed.
=back
=head1 RETURN VALUES
=over
=item setfacl
returns TRUE if successful and FALSE if unsuccessful.
=item 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,
C<getfacl> returns a null list.
=back
=head1 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
