This is a script to check if a TMW server is alive. By default, it checks the main server, but it takes 2 optional arguments: the hostname and the port. You can finger the login server and the char server, but not the map server. For example, $ tmwa-finger caliban.homeip.net $ tmwa-finger server.themanaworld.org 6902 $ tmwa-finger server.themana…

    echo "$1" >&2
    exit 1
}

    read -N1
    byte=$(printf %d \'"$REPLY")
    read $1 <<< "$byte"
}
readword() {

    readbyte low

    read $1 <<< $((high*256 + low))
}

    test $1 -eq 1
