linux will surely command - program running in the background - nohup, &

In Linux, allowing a program to run We usually use & at the end of the program running in the background to let the program automatically in the background.

For example, we want to run a Java program in the background:

　　 java -Xms512M -Xmx512M -Xmn200m -Xss4m -jar  project.jar  &。

But there are not many programs like Java, & does not work for some programs, then we can use nohup command:

　　nohup java -Xms512M -Xmx512M -Xmn200m -Xss4m -jar  project.jar 。
