    If so, his perl is broken. Quote rand,

    Automatically calls srand unless srand has already been called.

    >perl -e"print rand 1"

    Is there another way I can put the rand arguement in there? I have a text file with about 90000 lines and I just need to pick 300 lines randomly from it. Sorry for all the questions. I'm truly still a novice at this.
