[Help] Wake / Sleep on Lan Script

Hey Guys,

Main part starts after  the bottom bold part

I need help with writing a couple of scripts.
One to wake on lan and one to make it sleep.

So here's what I'm going to do:

I have a laptop and an old computer. My computer is the one that needs to be turned on and off. I want my laptop to trigger it on when it turns on and I want my computer to turn off after 100 failed pings to my computer.
I use netcfg2 on my laptop. So, when my laptop is on, AND is connected to my "home" network, it turns on  the computer.

So for this part, I was thinking of a script + cron daemon since I couldn't find a way to parse commands as netcfg2 connects.

To turn off my computer, same as above, script + cron daemon.
But my computer runs ubuntu though.

Now, if anyone has any way to parse commands after netcfg2 connects successfully, please let me know.

Need Help Here
So, what I need is to learn how write a bash script that can read the command line output.
Read as in being able to detect the outputs of a command.
So, if I did something like "netcfg2 -c home"and the output is "home already connected", then it should issue the command to wake up my computer.

But I have no clue on how to do that.

Any help to point me in the right direction would be very appreciated

TJ

P.S. Unless you guys want to write the script for me
Would make my life even easier.

P.S. #2, is there a way to make a script to login in ssh, then run a command in that ssh environment?

Re: [Help] Wake / Sleep on Lan Script

So, Ive inadvertently discovered a way to make it auto-on in much simpler way.
I made a mount point from my computer to my laptop and so now when ever my computer tries to mount it, it turns on the computer.

Now,
For the turning off part, I think I'm going to go with computer activity?
