In Terminal, I was doing a very simple dump of a directory ( ls > dirlist.txt ) and then somehow got wrong the mv command ( mv oldname* /User/Documents/NewName.txt ) which instantly did horrible things. I'll man mv later to figure out that part... However, I have noticed the Mac OS is not happy at all as I hosed my Pictures and other directories. Double-Tap select and drag and other things don't work. So, I am thinking I'll restore from my Time Machine, which requires a CNTRL R during boot. I tried googling and didn't find a solution so I'm hoping someone has gone through this and found a solution. I'm in Afghanistan, so I can't just go hop in the car and go to an Apple Store. I have the newer wireless keyboard (two batteries), a track pad, and a wired mouse. No wired keyboard. I can buy from an Afghan shop a PC Chinese-built keyboard, but I'm hoping I don't have to buy a keyboard I'll never use again.
