Newbie Linux scripting question

[baker0]

All Gurus

I am very new to Linux and im trying to setup an automatic shut down for our linux boxes via our UPS (if there’s a power outage). The UPS only allows a batch file to be run so ive come up with this idea...

I’ve come across plink to allow me to run the Linux command in a batch file:
plink 10.10.60.30 -l root -pw <password> -ssh /nas/sbin/nas_halt now

This works fine but after this command it prompts for a yes. Nas_halt command has no auto setting to input yes so it just sits there waiting for input.

Is there any way I could set this up? e.g getting plink to call a Linux script which calls nas_halt and inputs the yes after?? If so what would this be?

Any help would be superb.
Cheers

try the command "yes"

A Python script with Pexpect - Noah.org might work?

This should work:

yes | plink 10.10.60.30 -l root -pw <password> -ssh /nas/sbin/nas_halt now

If nas_halt is expecting "y" then piping the yes command will work. If nas_halt is expecting "yes' then do:

yes yes | plink 10.10.60.30 -l root -pw <password> -ssh /nas/sbin/nas_halt now
