| Aliases are not used in bash scripts, unless bash is invoked in POSIX
| compatibility mode, or the "expand_aliases" shopt is turned on.
I think that's what must have happened ... the infinite loop of
echo commands suggests that the function definition
cmd() { echo "$@" ; }
was converted by the alias info
echo() { echo "$@" ; }
and when you see that, it is obvious why cmd a b c (which becomes echo a b c)
just runs echo which runs echo which runs echo which ...
Whether POSIXLY_CORRECT is in the environment (that's what I did to get
the described behaviour) or for some other reason bash is set up to
operate in posix mode, it is fairly clear that is what happened.
Yet another reason to never use aliases, for anything, anywhere, they're
an abomination, and rarely accomplish what one might expect.
