hi all,
i installed minix 3.1.2a in my PC and then i compiled minix3.1.1 on it.
when i boot 3.1.1 and type in ls command it gives

ls :.:Invalid argument

where there is no argument
similarly in mv command
when i pass a valid file name it again says
Invalid argument


this problem is not there in 3.1.2a version

any clues will be hight appreciated


thanks in advance

regards
kanishk
