Linux: How to time that file was Changed, Modified or Accessed?

The Linux shell command to see or retrieve what time a file was changed is "stat".

ex. 

stat yourFileName.here

 [yourPrompt]# stat yourFileName.here
  File: `yourFileName.here'
  Size: 219             Blocks: 8          IO Block: 4096   regular file
Device: dh/3d  Inode: 30229777    Links: 1
Access: (0644/-rw-r--r--)  Uid: (  500/ownerName)   Gid: (  500/groupName)
Access: 2010-04-26 13:13:59.000000000 -0400
Modify: 2010-04-26 13:13:59.000000000 -0400
Change: 2013-05-24 18:04:27.000000000 -0400

You can also get results for multiple files using standard shortcut conventions.

ex. 

stat yourFile*

In this case, the stat command reveals that someone Changed a file yesterday, but the Modify and Access dates were not changed. 

Very clever bad boys out there....

Apparently, one may change the modification  date by using the "touch" command.
