[Linux] Auto Start Linux If Server Crash

[Fyruz]

Hello everyone, I am searching for a script or command on linux that if the server crash, or get down, it will automatically get online.
I want this script because I have a global server save each 24 hrs. and when the server save occurs my server shutdown (because i configure like that) but the server stays closed, thats why I want this script.
thank u

I know that this thread has few moths, but it is high on the Google's search list, so I responded, because it can be useful for someone else.
Bash script for Linux to keep server online after shutdown.
Tested under Ubuntu 13.10 with TFS version 1.0.

You can download it from assets.sekai.eu .
Move script into directory where you store your server executable. Remember to add executable permission for this file:

chmod +x keep-server-online.sh

You can run it as follows:

cd pathToYourOTS
./keep-server-online.sh serverExecutableFilename

For example if you keep your server in /srv/ots directory and your executable filename is tfs:

cd /srv/ots
./keep-server-online.sh tfs
