Question

I’ve been trying to run my java program overnight but I need to restart it sometimes to save it’s progress and completely reboot the machine. After a few hours I have the program save its progress and execute a little restart file to restart the program.

void restartServer() {
    try {
        Runtime rt = Runtime.getRuntime();
        rt.exec("./restart.bat");
    } catch (java.io.IOException err) {
        logError(err.getMessage());
    }
}

Inside restart.bat I have:

echo Restarting Server
killall -9 java
sleep 2;
nohup java -Xmx200m -classpath bin server.Main;

However it doesn’t work. It says:

[root@linode java]# ./restart.bat
Restarting Server
: no process killed
: command not found 3:
nohup: appending output to `nohup.out'
: command not found 4:
[root@linode java]#

Why does it say no process killed when there is a java process running? And why does it say command not found? It never restarts the program either.

Answer 1

How about putting #!/bin/sh or something like it as the first line of your restart.bat

BTW, .bat is a very poor choice of extension on linux system.
