Don't know what it will do since I don't know what you've been doing.
Drag and drop the dock preference file to the desktop or to the trash, log out and back in. The system will create a new preference file.
If the changes you made (I am assuming via the terminal) were done in that file, it should reset everything to default.
After you check it out, you can either trash the file or move it back where it came from.
My advice to those not familiar with the terminal and just have to change the way the dock looks - use Candybar
For those that are new to the command line, before you go about changing any system settings via the command line, I would highly recommend you learn some about the terminal
to the point of being at least somewhat comfortable using it prior to making any changes.
I would also suggest creating a text file to keep a log of system changes you make using the terminal. Particularly when first beginning.
