> This script:

> #!/bin/sh
> echo hello >hello.txt
> ls -l
> cat hell*
> cat < hell*

> gives me:

> $ ./t.sh
> total 2
> -rw-r--r-- 1 vp01mkf Domain Users  6 Aug 12 19:51 hello.txt
> -rwxr-xr-x 1 vp01mkf Domain Users 60 Aug 12 19:51 t.sh
> hello
> ./t.sh: line 5: hell*: No such file or directory

> But if I change line1 to
> #!/bin/bash
> I get
> hello
> hello
