There is certainly a way: You have to define the aliases in
the right rc file or profile. This depends on your login shell
(unfortunately you didn't mention which shell you're using).
For example, the zsh uses the following rc/profiles:
~/.zshenv read by EVERY zsh
~/.zprofile read by LOGIN shell only
~/.zshrc read by INTERACTIVE shell only
/.zlogin read by LOGIN shell only
So if you want to be really sure, put your aliases, functions,
variables, whatever into ~/.zshenv, which will be read by every
invocation of zsh. However, aliases are only useful for
interactive shells, so it is better to put them into ~/.zshrc
to avoid unnecessary overhead. Putting them in ~/.zprofile or
~/.zlogin wouldn't work with ``su -m'', because it doesn't run
a login shell.
All of that can be different with different shells. You should
read the section about startup files in the manpage of your
shell.

Oliver
