下面是两个执行Linux命令的例子:

包含文件：
import java.io.InputStreamReader;
import java.io.LineNumberReader;

/**
* 执行shell命令
*String[] cmd = { "sh", "-c", "lsmod |grep linuxVmux" }或者
*String[] cmd = { "sh", "-c", "./load_driver.sh" }
*int tp = 1 返回执行结果 非1 返回命令执行后的输出
*/
public String runCommand(String[] cmd,int tp){
StringBuffer buf = new StringBuffer(1000);
String rt="-1";
try {
Process pos = Runtime.getRuntime().exec(cmd);
pos.waitFor();
if(tp==1){
if(pos.exitValue()==0){
rt="1";
}
}else{
InputStreamReader ir = new InputStreamReader(pos.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String ln="";
while ((ln =input.readLine()) != null) {
buf.append(ln+"
");
}
rt = buf.toString();
input.close();
ir.close();
}
} catch (java.io.IOException e) {
rt=e.toString();
}catch (Exception e) {
rt=e.toString();
}
return rt;
}
/**
* 执行简单命令
* String cmd="ls"
*int tp = 1 返回执行结果 非1 返回命令执行后的输出
*/
public String runCommand(String cmd,int tp){
StringBuffer buf = new StringBuffer(1000);
String rt="-1";
try {
Process pos = Runtime.getRuntime().exec(cmd);
pos.waitFor();
if(tp==1){
if(pos.exitValue()==0){
rt="1";
}
}else{
InputStreamReader ir = new InputStreamReader(pos.getInputStream());
LineNumberReader input = new LineNumberReader(ir);
String ln="";
while ((ln =input.readLine()) != null) {
buf.append(ln+"
");
}
rt = buf.toString();
input.close();
ir.close();
}
} catch (java.io.IOException e) {
rt=e.toString();
}catch (Exception e) {
rt=e.toString();
}
return rt;
}

=================================
上述函数放在一个类中,需要的时候直接调用。
