If I recall correctly, /etc/profile, /etc/profile.d/*, and
~/.bash_profile are only eval'd in an interactive (login) shell.  You
probably want to place your alias in ~/.bashrc so it will be used in
all shells.

Working manually, could also define foo as a function instead of an
alias, and then export it:

[pfrields at localhost ~]$ foo() { ls -ld; }
[pfrields at localhost ~]$ foo
drwxr-xr-x 193 pfrields pfrields 12288 2008-12-01 09:00 .
[pfrields at localhost ~]$ export -f foo
[pfrields at localhost ~]$ bash
[pfrields at localhost ~]$ foo
drwxr-xr-x 193 pfrields pfrields 12288 2008-12-01 09:00 .
[pfrields at localhost ~]$ exit
