Bash Version: 2.04
Patch Level: 0
Release Status: release

Description:

I'm trying to emulate ksh's exported aliases and I'm having a problem
with 'shopt -s expand_aliases':  it doesn't seem to stay on between my
BASH_ENV file and my script.

Repeat-By:

For example, given these two files:

$HOME/my_bash_env:
echo Welcome to my_bash_env
echo This is bash $BASH_VERSION
shopt -s expand_aliases
shopt expand_aliases
echo

./my_script:
#!/usr/local/bin/bash
echo Welcome to my_script
shopt expand_aliases

Then

BASH_ENV=$HOME/my_bash_env ./my_script

Produces this:

Welcome to my_bash_env
This is bash 2.04.0(1)-release
expand_aliases  on

Welcome to my_script
expand_aliases  off

How did expand_aliases get turned off?  Is it a bash bug?

I've looked in bashref.info, the bash FAQ and Deja -- but I didn't find
an answer.

Any aliases I set in my BASH_ENV file are still set but they don't
expand since expand_aliases is off.

Thanks.
