Package org.eblocker.server.common.system.unix

Class ScriptRunnerUnix

java.lang.Object

org.eblocker.server.common.system.unix.ScriptRunnerUnix

All Implemented Interfaces:

ScriptRunner

public class ScriptRunnerUnix
extends Object
implements ScriptRunner

Runs a script with a sudo wrapper.

Since we can not send the SIGTERM signal to the script in order to stop it (the script runs as root, this server does not), we need a special kill script.
