    Dear Ravi
    Could you advise what does this {} \; parameter do in the command find / -size +100M -exec rm -rf {} \;

  6. srujan says:

    26.Find Last 50 Days Modified Files

    To find all the files which are modified 50 days back.

    # find / -mtime 50

    i think it should be -50 for last 50 days
    exact 50 days it should be 50

  7. Axel says:

    What is the difference between “Changed” (29) and “Modified” (30)?

    • Ravi Saive says:

      @Axel,

      29. The command find / -cmin -60 will list the files status was last changed x minutes ago and,

      30. The command find / -mmin -60 will list files data or content was last modified x minutes ago.

  8. Axel says:

    There’s a typo in:

    “19. Find all Empty Files
    To file all empty files under certain path.”

    “To file” -> “To find”

  9. Ramachandra says:

    Dear Sir,

    I want to search the hidden files for a particular duration of time.

    Please advise how to use the find command to search the above request.
