By default, aliases are only expanded in interactive shells. When you run a script, the shell is non-interactive.
I don't believe this is accurate.
Aliases defined within the script are expanded.
What often is the case is whether the "$ENV" file, typically ~/.bashrc,
is automatically sourced when starting a non-interactive instance of ksh.
The intended, primary purpose for aliases is to assist in your interactive
shell session. For example, I like the protection of the "-i" option of rm.
Thus I alias rm='rm -i'. But I would not like my scripts to pause, waiting
for my response, every time they remove a file.
If you really want to use aliases in a script, define them in the script.
Alternatively if certain aliases are used by many scripts, but them in a
separate file in your 'lib' directory and source them in with ". ~/lib/myaliases".
