lsattr lists filesystem extended attributes. These attributes are only possible on ext2 and ext3 filesystems. They do not work on reiserfs, xfs, jfs, fat32, ntfs, etc etc etc, and they also do not work on virtual filesystems like /proc. /proc is not a real filesystem, the files you see there are being presented by the kernel as a way to view (and in some cases set) kernel parameters. These are not real files, which is why you see bogus file sizes when doing an 'ls -l' for example. They are simply hooks into the information the kernel wants to make available. Normal file permissions (root-write for modifiable settings, user-write for /proc/$PID, and world read only for the rest) are all you have available, no extended attributes in /proc. -- Brian Hatch "It is not my day for Systems and talking seriously.
