Does Darwin/MacOS modify Bash?

Question

I\'m wondering about the portability of Bash scripts that use Bash built-in commands.

I understand that each flavor of UNIX tends to modify various UNIX utilities. B

Answer 1

bash version 4 is not shipping on Darwin or MacOS Lion. so the mac does not support the improvements to the read command, etc which is unfortunate.

cygwin has bash 4.1.10
