Just all of a sudden in the middle of a session, I can't get the "cd" command working! Whenever I try to CD to anything, I get: "-bash: .: /Users/Dauber: is a directory" The only time I get anything different is if I try to CD to a directory that doesn't exist, in which case I get, "No such file or directory." Rebooting didn't solve the problem. The only way around this is instead of "cd" I use "/usr/bin/cd" -- which is weird because no other commands in that directory have this issue. Any thoughts??? Oh, btw...OSX 10.11.4.
