Restart Linux

[xLosT]

How can i restart tfs only at scheduled time on linux?
I thought i'd do it for crontab, but how do i go back to the screen before running tfs


@edit
i creat sh with directory and work

#!/bin/bash
ulimit -c unlimited
while true; do cd /home/otserv && ./tfs; done

one more question, how do i see the tfs screen with pid id

In you server path, first you need save screen session with one name:
screen -A -S tfs

Later you run the file:
./restart.sh

So when you close the console window and enter again,
for see the screens with pid, only you do:
screen -x

Now appear a list of screens, finally you do:
screen -x pid
