Caveat: I am, by no means, a Unix geek. I'm all about web programming; doing stuff to my own machine is literally a different language, so I'm not surprised if I caused whatever the problem is. That said: I was trying to install a development copy of WordPress on my MBP using these directions, which start you off with installing MySQL. I downloaded & installed MySQL. The next step was turning MySQL on, and that's when things went wonky. Every sudo command (including stuff like "sudo ls") results in "command not found." A search turned up another thread in which the op was asked to do "which sudo" and "echo $PATH". I got "command not found" for the first, and for the second I got... /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/mysql/bin Unfortunately I have no earthly clue what that might mean. I did try turning MySQL on via the prefpane, so I don't know if that could've broken something? Or if my inept attempts to get PHP running a few months ago (which eventually were successful, but not without a good bit of mucking about) could be at the root of the problem? As I said, this is all Greek to me, so while any help is appreciated, help given in short syllables is appreciated more.
