Wow! people get emotional about this.
Even though sh->bash is common, it is "wrong", and causes some valid 
Unix scripts to fail on Linux.
The alternative just breaks thousands of "incorrect" scripts :-)

Anyway, I suggest you stop learning both. Who can respect a shell
where wildcard expansion leaves the wilcard as a literal when it doesnt 

$ ls
a1 a2 a3 b1
$ echo a*
  a1 a2 a3
$ echo foo*

What was Steve thinking?
