Hi guys, I'm a newbie to the UNIX OS, I need to know if I can write scripts to automate commands and if I can, how would I do it...

I need to take CPU and memory utilization readings (as well as other commands, such as iostat, mpstat, vmstat, etc) of the UNIX box every 10 seconds or so... dump those readings into a text file for graphing, etc.

Does anyone know if there is a utility that already does this? If not, does anyone have any sample scripts that I can view?

Thanks

Hmm, some UNIX's have a routine called:

perfmeter

Try looking for that.

One word of warning, just using this or any other utility will squeue your results, at least a little.

Hope this helps, good luck.

Make a script like this

# !/bin/sh

iostat >> /path/to/log &
mpstat >> /path/to/log &
vmstat >> /path/to/log &

and then add a line in
/etc/crontab
saying something like this ..

1 * * * * root /path/to/script

this means cron will start the script every minute ... i think you can't specify seconds
to cron ....

Of course for you to be able to do this
cron daemon has to be started ....
But most unix-es start it by default during boot ...

Hi Everyone,

I need help with Unix. I have to write a script that will convert currency. It has
to convert US to Canadian dollars and vice versa. And it should be able to convert anyother currency.

Thanks
