java調用shell命令並獲取執行結果的示例

使用到Process和Runtime兩個類，返回值通過Process類的getInputStream()方法獲取

package ark;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;

public class ReadCmdLine {
public static void main(String args[]) {
Process process = null;
List<String> processList = new ArrayList<String>();
try {
process = Runtime.getRuntime().exec("ps -aux");
BufferedReader input = new BufferedReader(new InputStreamReader(process.getInputStream()));
String line = "";
while ((line = input.readLine()) != null) {
processList.add(line);
}
input.close();
} catch (IOException e) {
e.printStackTrace();
}

for (String line : processList) {
System.out.println(line);
}
}
}
調用shell腳本，判斷是否正常執行，如果正常結束，Process的waitFor()方法返回0

public static void callShell(String shellString) {
try {
Process process = Runtime.getRuntime().exec(shellString);
int exitValue = process.waitFor();
if (0 != exitValue) {
log.error("call shell failed. error code is :" + exitValue);
}
} catch (Throwable e) {
log.error("call shell failed. " + e);
}
}
