Question crontab entry


hey all,

How can I specify the crontab entry or entries which will append the contents of /proc/loadavg to the file /var/log/loads. This is to be done between the hours of 6am to 6pm at 5 minute intervals, Monday to Friday. On Monday to Friday, after hours, it should run every 15 minutes. On the weekend, all hours, it should be run every 30 minutes.

thanx in advance

Simple enough.


cat /proc/loadavg >> /var/log/loads


>> will append to a file.

You could do something like:

date >> /var/log/loads && cat /proc/loadavg >> /var/log/loads


That will first append the current time/date, and then append the loadavg file.

(Make sure you don't use just > because that will overwrite the file and create a new one)

Making the crontab entries themselves should be fairly easy from that point out. The are MANY excellent tutorials on using cron on the web.

That is an excellent tutorial on learning how to use crontab. It explains everything you need to know to get everything up and running the way you want it to.

Not trying to be rude by just sending you a link, but there is no need to reinvent the wheel if someone else has already written something comprehensive on the subject. If you don't like his tutorial, try doing a google for "crontab tutorial". I just did, and dozens upon dozens came up.
