java 代码执行linux命令

在做一个java执行pyhton脚本命令时在网上找了许多方案都不行，最后在stackoverflow上
找到，执行脚本的时候需要带上shell的版本，类似于bash，zsh。看了下服务器上的是zsh，

于是优化代码如下：

package com.xiamu.utils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.BufferedReader;
import java.io.InputStreamReader;
/**
 * Description: 调用脚本帮助类
 *
 * @author haoyuan.yang
 * @version 1.0
 * @date: 2017/3/10
 * @since JDK 1.8
 */
public class PythonUtil {
	private static final Logger logger = LoggerFactory.getLogger(PythonUtil.class);
	/**
	 * Description:调用系统命令
	 *
	 * @author haoyuan.yang
	 * @version 1.0
	 * @date: 2017/3/10 17:55
	 * @since JDK 1.8
	 */
	public static void executeCommand(String command) {
		try {
			Process proc = Runtime.getRuntime()
					.exec(new String[] { "zsh", "-c", command });
			proc.waitFor();
			BufferedReader reader = new BufferedReader(
					new InputStreamReader(proc.getInputStream()));
			StringBuilder sb = new StringBuilder();
			String line;
			while ((line = reader.readLine()) != null) {
				sb.append(line).append("\n");
			}
			logger.info("execute command {} , result is {}", command, sb.toString());
		}
		catch (Exception e) {
			logger.info("execute command {} fault, e={}", command, e.getMessage());
		}
	}
}
