Changing Preferences in Command Line?

內容

I need help from you power users...

I am now working somewhere three to four hours away from my old office. Last weekend I went back to my office, turned on my Mac, turned on the "remote login" option, and hoped that I could ssh to my Mac from another place.

This morning, however, when I tried to ssh to the Mac I couldn't get connected. I am guessing that it might be sleeping -- I forgot to turn that option off.

So I am planning to take the following actions:
<UL TYPE=SQUARE><LI>Make a phone call to my friend in the office, ask them to wake up my computer (they are not Mac users, I have locked my screen and I remembered the primary language was set to Chinese -- so I wouldn't ask them to do the next step for me).
<LI>Remotely login to my Mac, and turn off the corresponding energy saver options using command line so that it won't sleep again.</UL>

The question is how do I do the second step: changing the preference settings in command line?

Thanks.

Dear Paladin:
How about VNC?

Provided that I can install VNC via the command line interface...

Well, the command line interface is the only means I can access the Mac, also the only thing I need. I now just need a way to alter the preference setting so the computer wouldn't go to sleep when I am not around.

sudo pico /private/var/db/SystemConfiguration/com.apple.PowerManagement.xml

把 Wake On LAN 改成 1（碰一下就醒來）
把 System Sleep Timer 改成 0（不睡覺）

Great! Thanks. Will try it when there is someone in the office.

BTW, in what document/books I find information like that?

You might need something like this as well:

i.e. waking up an eMac locally from my Indy:
