You're using a bash feature, so make sure your script is being executed
by bash, not by /bin/sh.

If you explicitly type "sh myscript" then that's the problem right there.
Type bash instead of sh.

If you type "./myscript" or "myscript" (if PATH contains it) then the
interpreter is chosen by the shebang header.  So make sure the header
is #!/bin/bash or equivalent.  #!/bin/sh will not work.
