Hi: there! I want to run certain scripts at certain time, say 10:00 send email to myself to remind something. But I don't know how to let the OS to run the script at the specified time. Any suggestions? Thanks a lot Nancy

You use cron to do this. The command "crontab -e" allows you to edit the cron file. Adding the following line to the cron file would cause the script "/dirpath/myscript.sh" to execute every day at 10:00. 0 10 * * * /dirpath/myscript.sh >/dev/null 0 is the minute 10 is the hour the three * add up to 'every day' Use 'man crontab' for more details.

You can alo use the "at" command for one-off things (cron would be better for a recurring job) $ at 22:00 type commands ended by Ctrl&D The commands will now be run at 10pm (and then forgotten about)

Thanks a lot. Nancy
