alias ls does not work in screen

[Jingxin Feng]

Hello,

I set up alias ls as ls -F --color=auto in .bash_profile and it works fine. However, when I start screen, it does not work. Do I need any special setting in .screenrc? Thanks

system: 2.6.35.13-92.fc14.x86_64

.screenrc

hardstatus alwayslastline

hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{=kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B}%Y-%m-%d %{W}%c %{g}]'

# Default screens

......

altscreen on

shell $SHELL

Thanks a lot!
