Thanks! This worked out for me. It was strange though, the first time I ran it, nothing happened. After that, files were shown/hidden as one would expect (I'm on OS X 10.8.2). It'd be cool to be able to right click anywhere in the finder to get this option in the context menu ... Looks like one can only make this work if a file/folder is selected?

So helpful! Thank you!

Hi, thanks for script, but it doesn't work on OS X 10.8.4 and shows error: "-: -c: line 4: syntax error near unexpected token 'else' ". When I checked manual for UNIX & Linux Shell Scripting (If & Else), I found that correct is
if [ $is_shown = "FALSE" ]; (added semicolon) and it works fine now.

Works perfectly in OS X 10.9.2, thank you!

Works in Yosemite. Special thanks @iCoderman
