Find all directories that have been modified today on a particular mount point in Linux

To find all directories that have been modified today on a particular mount point in Linux, you can use the find command. 

Here is an example:

find /path/to/mount/point -type d -mtime 0

This command will find all directories (-type d) under the directory /path/to/mount/point that were modified within the last day (-mtime 0)1.

Please replace /path/to/mount/point with your actual mount point.

Remember, this command will only find directories that were modified within the last day. If you want to find directories that were modified on a specific date, you can use the -newermt option with find1:

find /path/to/mount/point -type d -newermt "YYYY-MM-DD" ! -newermt "YYYY-MM-DD"

Replace “YYYY-MM-DD” with the date you are interested in1. This command will find all directories that were modified on that specific date1.
