Greetings!

cp is the unix "copy" command. The directory listing (ls) you did of the /lib directory showed the library file. But it looked kind of odd that it seemed to span multiple lines with multiple zeros. So, you copied the file that looked like it had the wrong name to the proper name. That seemed to do the trick.

Congrats on the promotion!!! Did you ever get credit for you posts under your old username?

Edit: before anyone asks, I recommended the copy rather than the move (mv) because I was not sure if it was a typo or not, and wanted to keep the old file in place, just in case...
