【JAVA 中执行Shell】

jShell.java

/*
* jShell.java
* class jShell is used for executing shell command
* USAGE:
* jShell obj=new jShell(shellCommand);
* obj.startErr();
* obj.startOut();
* obj.startIn();
* You can Interupt I/O thread when nessasary:
* obj.interruptErr();
* obj.interruptOut();
* obj.interruptIn();

CODE: mainC.java

public final class mainC {
public static void main(String[] args) {
jShell shell=new jShell("ls -l");
shell.startErr();
shell.startIn();
shell.startOut();
}
}

PS:

Process process=Runtime.getRuntime().exec("");中产生停滞（阻塞，blocking），怎么解决？
---------------------------------------------------------------

这个是因为Runtime.getRuntime().exec()要自己去处理stdout和stderr的。
所以如果你想让程序正常运行的话，请务必将上述用别的线程流取走。

【JAVA中执行bat】

>test.bat
haha
exit 99

>RuntimeTest.java
public class RuntimeTest {

public static void main(String[] args) {
try {
Process process=Runtime.getRuntime().exec("test.bat");
StreamGobbler errorGobbler = new StreamGobbler(process.getErrorStream(), "ERROR");

// kick off stderr
errorGobbler.start();

StreamGobbler outGobbler = new StreamGobbler(process.getInputStream(), "STDOUT");
// kick off stdout
outGobbler.start();

process.waitFor();
System.out.println(process.exitValue());
} catch(Exception e) {}
}
}

>StreamGobbler.java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintWriter;

public class StreamGobbler extends Thread {
InputStream is;
String type;
OutputStream os;

StreamGobbler(InputStream is, String type) {
this(is, type, null);
}

StreamGobbler(InputStream is, String type, OutputStream redirect) {
this.is = is;
this.type = type;
this.os = redirect;
}

public void run() {
try {
PrintWriter pw = null;
if (os != null)
pw = new PrintWriter(os);

InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null) {
if (pw != null)
pw.println(line);
System.out.println(type + ">" + line);
}
if (pw != null)
pw.flush();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
