Use crontab to run the script of executing jar program regularly in centOS6

1. Write a simple Java program

public class testshell {
  public static void main(String[] args) {
    int count = 0;
    for (String arg : args) {
      System.out.println("The " + (++count) + " parameter: " + arg);
    }
  }
}

Package the above program into centOS6

2. Write a shell script

#!/bin/bash
export JAVA_HOME=/usr/local/jdk1.8.0_91
export PATH=$JAVA_HOME/bin:$PATH
A=`date`
java -cp /root/Desktop/testshell.jar com.testshell "$A" >>/root/Desktop/c.txt

Here, please note that the absolute path address of the jar package in the Java environment variable is written

3. Edit the timer file (crontab -e)

*/1 * * * * /root/Desktop/b.sh
