Script for Garrettcom make Switches

Hi,

I have 20 garrettcom make switches, model is 6kq, In these switches space for logs is very low and logs in the switches are generating continuously.

After Some days Switches are getting hanged due to unavailability of space for Log . For clearing of log I fire command in the switches which is "Clear Log" after putting command it ask for confirmation with "y/n".

I want to schedule a job with these commands, Can any body help me in creation of Script for these switches.

Thanks
