   This has been answered more than adequately in the comp.unix.shell
   newsgroup.

   The correct answer, which you seem not to like, is, "Don't use
   aliases; use functions."

   that.

   As I said before, this works for me in both 2.05b and 3.0.

   I also suggested adding "shopt -s expand_aliases" to the script.
   You replied that is wasn't necessary. You didn't try it and still
   complained that your script didn't work.
