+- **Question:** I would like to delete directories older than two days from /fullbackup/archive path. How do you do it using any scripting methods.
+
+- **Problem Statement:** I was trying to use ```find /path/ -type d -mtime +2 -print0 | xargs -r0 rm --```. This command does not works as expcted due to directory modified date for SAT, SUN and MON are Mondays date.
