How to periodically remove temporary files in Linux

To remove periodically some files from a specific directory you can easily setup a cron entry. Execute in shell

crontab -e

and add

*/60 * * * * find /home/my_home/some_dir/ -name '*.dat' -mmin +60 -exec rm {} \;

where .dat is the suffix of the files and "-mmin +60 -exec rm {}" is the option telling to remove the files with data modified more than 60 minutes ago.

If your crontab uses Vim for editing use :wq to save you changes and "INSERT", "ESC" to switch between Insert and Normal mode.
