Problem with revealing a hidden folder I have a problem. I used command chflags hidden to hide a folder named !_TRANSCODE. Now I'm trying to undo this by typing chflags no hidden !_TRANSCODE and I get this error: -bash: !_TRANSCODE: event not found

Any help appreciated!
You should escape the !.

Try:

chflags nohidden \!_TRANSCODE


! is a special character to bash, it is used to refer to previous commands. A more extensive explanation can be found at: What is “-bash: !”: event not found"
