In order to run this command you don’t need to have access rights to the file, but you do need to be able to search all the directories in the path leading up to the file location. stat gives you lots of detailed information about a file, such as device number, inode number, access rights, number of hard links, owner user ID and name, owner group ID and name, device type, total file size, number of allocated blocks for the file, IO block size, last access time, last modification time, and — last but not least — last changed time , source: 9787115101440 network system download here
