NAME

Filesys::Ext2 - Interface to e2fs filesystem attributes

SYNOPSIS

use Filesys::Ext2 qw(:all);
$mode = lsattr("/etc/passwd");
chattr("+aud", "/etc/passwd");
#or equivalently
#chattr($mode|0x0062, "/etc/passwd");

DESCRIPTION

You may specify the path of the e2fsprogs upon use

use Filesys::Ext2 {PATH=>'/path/to/binaries'};

Otherwise the module will use the default path /usr/bin/

chattr($mask, @files)

Change the mode of @files to match $mask. $mask may be a symbolic mode or a bitmask.

Check $? upon failure.

lsattr($file)

In list context it returns a list containing symbols representing the symbolic mode of $file. In scalar context it returns a bitmask.

Check $? upon failure.

lstat($file)

Same as CORE::lstat, but appends the numerical attribute bitmask.

stat($file)

Same as CORE::stat, but appends the numerical attribute bitmask.

calcSymMask($mask)

Accepts a bitmask and returns the symbolic mode. In list context it returns a symbol list like lsattr, in scalar context it returns a string that matches the -------- region of lsattr(1) (akin to that of ls -l e.g. drwxr-x---)

SEE ALSO

chattr(1), lsattr(1)

NOTES

Of course, this would be more efficient if it were an XSUB.
