From the man page:
Quote:
Aliases are not expanded when the shell is not interactive, unless the
expand_aliases shell option is set using shopt (see the description of shopt under
SHELL BUILTIN COMMANDS below).
I never realized that before now. I guess it's since I can't think of a time when I've ever used aliases in a bash script...
In fact, I don't think I've ever used shopt before either, although I use disown every now and again...
