Files can be locked on OS X by going to the "Get Info" panel for the specific file and clicking the lock button.

I would need to remove locks from a shell script. What unix command can do that?

If you've got xcode installed, /Developer/Tools/SetFile. To unlock:

% SetFile -a l <path>

To lock:

% SetFile -a L <path>

To query, you can use /Developer/Tools/GetFileInfo
