How to find files which are not modified in last 15 minutes

[OScar123]

Hi Group,

I have a directory with lots of subdirectories created by a Software.

Many files are created in these sub directories and picked by another software.

I want to write a cron job to list the files which are not being picked up in last 15 minutes .

How can I use the find command to list down the files which have a timestamp of more than 15 minutes.

ie: . SYSTEM TIME-File TImestamp > 15 mins

Please help with find command or any other script.

Unfortunately HP-UX's find only has granularity of days.  To get smaller, you need a reference file and you must be able to do date arithmetic to figure out what's 15 minutes ago.

touch MMDDhhmm ref_file

find path -type f ! -newer ref_file
