Oh, really?
On my RH8 box I just get:
------------------------------<snip!>------------------------------
[EMAIL PROTECTED] dk]$ cat foo.sh
#!/bin/sh
function helloworld() {
echo "Hello, World!"
}
helloworld ();
[EMAIL PROTECTED] dk]$ ./foo.sh
./foo.sh: line 7: syntax error near unexpected token `;'
./foo.sh: line 7: `helloworld ();'
------------------------------<snip!>------------------------------
This isn't C. To invoke helloword, you just put it as a line on it's own:
> helloworld
If you wanted to pass args, they would just be words following the
command:
> helloworld arg1 arg2 arg3
The brackets are only used in the definition, not the invocation.

On cygwin, sh is in fact bash. At least, it is these days. Formerly, it
used to be ash, and that's the version you have on your machine; and the
syntax for functions you are using only works in bash.
Either specify /bin/bash in the shebang, or update your cygwin install
(specifically the bash package).
