-----------
To find the most recently modified files, sorted in the reverse order of update time (i.e., the most recently updated files first):
$ find /etc -type f -printf '%TY-%Tm-%Td %TT %p\n' | sort -r 

To search for files in /target_directory and all its sub-directories, that have been modified in the last 60 minutes:
$ find /target_directory -type f -mmin -60

To search for files in /target_directory and all its sub-directories, that have been modified in the last 2 days:
$ find /target_directory -type f -mtime -2

To search for files in /target_directory and all its sub-directories no more than 3 levels deep, that have been modified in the last 2 days:
$ find /target_directory -type f -mtime -2 -depth -3

You can also specify the range of update time. To search for files in /target_directory and all its sub-directories, that have been modified in the last 7 days, but not in the last 3 days:
$ find /target_directory -type f -mtime -7 ! -mtime -3

All these commands so far only print out the locations of files that are matched. You can also get detailed file attributes of recently modified files, using "-exec" option as follows.

To search for files in /target_directory (and all its sub-directories) that have been modified in the last 60 minutes, and print out their file attributes:
$ find /target_directory -type f -mmin -60 -exec ls -al {} \;

Alternatively, you can use xargs command to achieve the same thing:
$ find /target_directory -type f -mmin -60 | xargs ls -l
