Most Linux administrators are aware of the three standard timestamps associated with a file, i.e. ctime, atime and mtime. What you may not be aware of is that many of the modern filesystems on Linux such as EXT4 and BTRFS also support a file creation timestamp. Here is what the stat command outputs on RHEL 6.4: # stat helloworld File: `helloworld’ Size: 6470 Blocks: 16 IO Block: 4096 regular file Device: 803h/2051d Inode: 396942 Links: 1 Access: (0775/-rwxrwxr-x) Uid: ( 500/ fpm) Gid: ( 500/ fpm) Access: 2014-05-14 06:30:45.107878096 -0700 Modify: 2014-05-14 06:30:36.337878203 -0700 Change: 2014-05-14 06:30:36.337878203 -0700 and here
