View source for Atime

Time of last access of a file, the information is taken from the [[inode]], only if the [[filesystem]] doesn't have the noatime option.

 $ stat -s [[variable|$disk]] | tr ' ' '\n' | grep atime
 st_atime=1130490958
 $ date -r 1130490958
 Fri Oct 28 11:15:58 CEST 2005
 $ ls -luT disk

It can be helpful reading the atime of a script to see when it was last run.  Perhaps an rc script to see when a service was started/stoppped/restarted.
