Linux find accessed and modified files

Finding accessed and modified files might be necessary at times to check or for audit purposes.
If files kept in a folder or directory has been accessed or modified but should not be the case then something dubious is going on. 
In Linux finding accessed and modified files can be done in a one liner command.
find /home -type f -amin -60 || -mmin -60 -print
Above command will find or show any files accessed within the last 60 minutes with the option "-amin" and it will show also the files modified within the last 60 minutes with the option "-mmin".
A shell script can be created and further processing can be done when files are detected.
The time can be adjusted if there's a need, but a more robust solution to check any accessed or modified files should be a file system watcher, but above command is quite helpful to check any activity that should not be occurring.
