[英]Java: Run multiple shell commands?
OK. 好。 I've been looking everywhere on how to execute multiple commands on a single command prompt from java.
我到处都在寻找如何从Java在单个命令提示符下执行多个命令的地方。 What i need to do is this, but not in command line, in code.
我需要做的是执行此操作,而不是在命令行中执行代码。
Execute: 执行:
cd C:/Android/SDK/platform-tools
adb install superuser.apk
..Basically i want to run adb commands from a program!!! ..基本上我想从程序中运行adb命令!!! Here is my java code so far:
到目前为止,这是我的Java代码:
MainProgram.java MainProgram.java
public class MainProgram {
public static void main(String[] args) {
CMD shell = new CMD();
shell.execute("cmd /K cd C:/Android/SDK/platform-tools"); //command 1
shell.execute("cmd /C adb install vending.apk"); // command 2
}
}
CMD.java CMD.java
import java.io.BufferedReader;
import java.io.InputStreamReader;
public class CMD {
CMD() {
}
// THIS METHOD IS WHERE THE PROBLEM IS
void execute(String command) {
try
{
Process p = Runtime.getRuntime().exec(command);
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
// read the output from the command
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
}
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
}
catch(Exception e){
e.printStackTrace();
}
}
}
So what happens is...i can run the first command, but that cmd terminates and when i execute the 2nd command, a new cmd is created, hence i get an error because im not in the right directory. 所以发生的是...我可以运行第一个命令,但是该cmd终止,当我执行第二个命令时,会创建一个新的cmd,因此由于im不在正确的目录中,因此我得到了一个错误。 I tried a single string command "cmd /C cd C:/blablabla /C adb remount", but that just froze up...
我尝试了单个字符串命令“ cmd / C cd C:/ blablabla / C adb remount”,但是那只是冻结了...
Essentially, command 1 is executed and terminated, then command 2 is executed and terminated. 本质上,命令1被执行并终止,然后命令2被执行并终止。 I want it to be like this: command 1 executed, command 2 executed, terminated.
我希望它是这样的:执行命令1,执行命令2,终止。
Basically i'm asking how can i run both of these commands in a row on a single command prompt??? 基本上我问我如何在单个命令提示符下连续运行这两个命令?
My final target is to have a JFrame with a bunch of buttons which execute different adb commands when clicked on. 我的最终目标是拥有一个带有一堆按钮的JFrame,这些按钮在单击时会执行不同的adb命令。
Easiest way is to make a batch file then call that from program of course you could just say 最简单的方法是制作一个批处理文件,然后从程序中调用该文件,您当然可以说
C:/Android/SDK/platform-tools/adb install superuser.apk
there's no need to cd to a file if you name it directly 如果直接命名,则无需CD到文件
although what you are looking for is already made in ddms.bat which provides a complete visual link to adb 尽管您正在寻找的东西已经在ddms.bat中完成,它提供了到adb的完整可视链接
Create file as something.bat
and set the contents to: 将文件创建为
something.bat
并将内容设置为:
cd C:/Android/SDK/platform-tools
adb install superuser.apk
Then call: 然后致电:
Process p = Runtime.getRuntime().exec("something.bat");
all commands in the bat file are executed. bat文件中的所有命令都将执行。
