This doesn't really seem like a sufficient explanation. Putting such things in
.profile is pretty standard too. .profile should only ever be run by login
shells -- not even all interactive shells -- in the first place.
Moreover, bash at least will not expand aliases for non-interactive shells:
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).
So either this user has this expand_aliases shell option set. Or he's using
Solaris's /bin/sh which is a non-POSIX ksh derivative and that shell is both
1) running .profile for a non-interactive shell (which is utterly bogus) and
2) expanding aliases for a non-interactive shell.
I'm skeptical that it's doing that and if it is then it would be causing
problems for virtually any /bin/sh script. *Many* users would have commands in
.profile that are intended to only run once at login time.
I suspect something stranger going on. Perhaps /bin/sh on this machine is bash
and this user has some environment variable set that enables this non-standard
behaviour?
