Hi all,

How do I write top processes into log file periodically?
Thanks ahead.

You'll need to run top as "top -n 1 >> /path/to/logfile" so it will display one page then exit.

If you only want, say, the results for the first ten processes use:

top -n 1 | head -n 17 >> /path/to/logfile

The first seven lines are the header at the top of the output, followed by ten lines of processes.

You need to create an entry in cron to do this. See https://help.ubuntu.com/community/CronHowto
