GRASS installation problem

[Wengui Su]

Hi, everybody

I just installed GRASS binary distribution for Linux on my Official RedHat Linux4.1 box. Everything is fine except when I start GRASS, it does not stay in GRASS, and instead, goes into shell. That mean I cann't use any GRASS commands. When I type exit, it goes back to GRASS and quit. There is no error message come up. Any idear about this?

thanks
