Hi,

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

Is that correct behaviour. I guess so, but why? And what is the rule?
