By using stat command, you can see that information.

Code:
# stat somefile.txt
  File: `somefile.txt'
  Size: 9               Blocks: 2          IO Block: 512    regular file
Device: 475001dh/74776605d      Inode: 1161        Links: 1
Access: (0664/-rw-rw-r--)  Uid: (    0/    root)   Gid: (    0/    root)
Access: 2015-09-09 13:14:00.384836768 +0200
Modify: 2015-09-09 13:14:00.385346153 +0200
Change: 2015-09-09 13:14:00.385994348 +0200

If you change atime to off, the Access part will not be update when you access the file and you will gain minor to none performance depending on the filesystem structure.

Hope that helps

Peasant.

mtime, ctime, and atime

Why updating atime doesn't update ctime?

Hi, ctime is the inode change time. If reading a file, its atime will be updated, which should cause inode member i_atime changed, which is an inode change. So ctime should also be updated. But if I try to ls a directory on redhat, only the directory atime gets updated, not ctime. Why? THANKS! (2 Replies)
