Code:
$ top -d2 | awk '/CPU states/'
CPU states:  7.8% user,  0.0% nice,  1.2% system,  1.2% interrupt, 89.8% idle
$

This shows you the load of the CPU. If you want to redirect the output to some file and use it in some shell script you can do it like this:

Code:
# !/bin/sh
top -d2 | awk '/CPU states/' >> file.log

After you changed the file permissions to have "execute" rights, add it to /etc/crontab to run it every minute/hour/day...

top -d2 | awk '/CPU states/'

This code, put the xterm into halt mode. I can't see the output????

Try using this:

Code:
#!/usr/bin/ksh
uptime >> some_log_file

The rest of the things are just as posted by Sergiu. You can schedule it in cron or whatever..
