This might be a very basic question but I can't find the solution... I am looking for a simple way to check, on the Linux shell, whether there has been an update or access to the files *at all* in a certain directory (recursively) in the last xx mins, hrs etc. I would only need the answer yes or no, and would like to do it quickly: it would suffice if a command/script returns 'yes' when a single file has been found that has been updated recently, and stops.
'find -atime/-mtime' or 'test -e' comes to my mind but the former is a bit of an overkill, and for the latter, I don't really know how I could use it for the existence of 'a file updated recently'.
Advice would be appreciated.
