Command to find last time file was opened
New to unix .. Is there a simple command or utility that will tell me when the last time a file was opened/used?

Yes. A file has three time stamps

Code:
              time_t    st_atime;   /* time of last access */
              time_t    st_mtime;   /* time of last modification */
              time_t    st_ctime;   /* time of last status change */

In Linux the program "stat" will let you see the different time stamps.

Also, with Linux the "ls" command has the following option

Code:
       --time=WORD
              with -l, show time as WORD instead of modification time:  atime,
              access,  use, ctime or status; use specified time as sort key if
              --sort=time

one reminder

if the file system is mounted with no atime option for performance reasons, access time will not be updated then.
