I wanted to create few files which are Write Once Read Many (WORM). How do I do this? I assigned a permission level of 4000 to a file. Also I have to set retention to the files.So I created a file. Set the permission levels to 4000 and then used the touch command to set the retention to a specific time.touch -a -t 201303240215.10 a.txt.When I ran the stat command I got this.File: `a.txt'  Size: 6               Blocks: 8          IO Block: 4096   regular fileDevice: fd00h/64768d    Inode: 19267589    Links: 1Access: (0400/-r--------)  Uid: (    0/    root)   Gid: (    0/    root)Access: 2013-03-24 02:15:10.000000000 -0600Modify: 2013-03-23 05:41:45.000000000 -0600Change: 2013-03-24 02:00:53.000000000 -0600Is this the way to create a WORM file?
