import java.io.BufferedReader; import java.io.InputStreamReader; public class Shell { public static void main(String[] args) { String command = "ls -l"; test(command); } public static void test(String command) { Process process = null; try { process = Runtime.getRuntime().exec(command); BufferedReader reader = new BufferedReader( new InputStreamReader( process.getInputStream())); String data = ""; while((data = reader.readLine()) != null) { System.out.println(data); } int exitValue = process.waitFor(); if(exitValue != 0) { System.out.println("error"); } } catch(Exception e) { e.printStackTrace(); } } }
Process exec(String command) :在一個單獨的執行緒中執行此命令
waitFor()命令執行成功返回0,getInputStream()獲取命令的輸出
- Process exec(String command)
- 在單獨的程序中執行指定的字串命令。
