Unning DOS commands

Is there any way to run a command-line (DOS) command from within Java? For instance, If I wanted to run another app from a java program, and used a DOS command like app.exe -param1 -param2 ?

Is it possible to call ms-dos command in abap program?

Hi,
is it possible to call ms-dos command in abap program?
Thanks.

Hi Cemil,
You probably have your answer here:
[Re: DOS/Windows command in app server;
You create your external command with SM69 (you can test it with SM49).
Then you call this command with function module "SXPG_COMMAND_EXECUTE".
(See function group SXPT for all the calls to external commands).

How to run multiple DOS commands from a single Webutil Client_Host session?

Hello all,
I have a requirement where I need to create an interface with SVN from Forms for basic checkin-checkout of files.
So, I've been trying to use webutil client_host to open a command line session and issue svn commands.
For svn, sometimes I need to give multiple commands like change to a particular directory and then run an svn command.
But client_host takes in only one command at a time and I'm unable to issue a series of DOS commands to perform
a particular task.
Is there a way to do this?
Pls suggest.
Regards,
Sam

First your original question... You can put more than one DOS command on a single line, simply separate each command with an ampersand (&). For example:
mkdir c:\abc & cd abc & dir*
Regarding your concerns about performance, well that would depend on exactly what you mean. Using CLIENT_HOST (or HOST on the server) simply opens a shell (DOS in this case) then passes your command to it. The performance of performing this action really isn't measurable. Basically you are just pressing a button and you should get a near immediate action. As for the performance of executing each command, that has nothing to do with Forms. Once the command is passed to the shell, the rest is a function of the shell and whatever command you passed.
Having said that, if you were to write something sloppy like a loop (in pl/sql) which called CLIENT_HOST lots of times repeatedly, then yes there would be a performance problem because the pushing of the button will cause an exchange to and from the server and each cycle in the loop will do the same.
So the answer to how performance is impacted will depend on what exactly you need to accomplish. If it is a single call to CLIENT_HOST, this should be fine.

Is there a way to run dos commands on onther system?

Hi I have connected to a port of another system where windows is the operating system. So can I run dos commands on the other system through that network connection from my computer?

I'm not sure what you mean by "connected to a port of another system" . Which port using what software to which server?

Execute DOS command in current window!

All:
Here is my code :
import java.io.*;
public class BuildScript {
public static void main ( String[] args ) {
String[] command = {"C:\\winnt\\system32\\cmd.exe", "cls"};
try {
Process process = Runtime.getRuntime().exec ( command );
process.waitFor();
} catch ( InterruptedException e ) {
e.printStackTrace();
System.exit(-1);
} catch ( IOException e ) {
e.printStackTrace();
System.exit(-1);
System.out.println ( "DONE!" );
I just want to exeute some simple DOS command from Java application. And then I run this code, it hangs there for ever. I comments out "process.waitFor()", then it print out the "DONE" however it seems that it just open another console and clear that one and exit. For the main console I start my code, nothing happened.
Can anyone help me out how to execute the dos command in current console window.
Thanks

Can anyone help me out how to execute the dos command in current console window.Sorry to say but there is no way to do that.
The best way to clear the screen is to print a few hundred newlines.
Trust me, this is a frequently asked question.

Is it possible to run dos-command's in java?

I have a small security problem. I have a dos-based java prog. with login at the start og the program, but I have problems hiding the password. I have managed to hide the password when it is typed, but when you press enter and get to the next menu, it is only to press the up-key, and dos recover the last typed sentence. (The password...) I have been able to fine the dos-command "doskey /reinstall", which will clear the memory, but I haven't been able to implemet this in my java-prog.
Any tips/trics are appreciated.

I doubt that calling that in your program would help.
doskey is specific to the process. Running it by any means in java means that a new process will exist. You can verify this by open two console windows and running doskey in both. Nothing that you do in one will be reflected in the other.
I don't think your problem is a program problem. That means that it should not be solved by software but rather by management. For example you certainly wouldn't expect your program to make sure that someone wasn't standing behind the user when they typed their password right? And what if someone installs a key grabber on the computer? In that case any program, yours included, would have all the key presses logged to a file.
Alternatively if you might be able to solve it with one of the following...
- Recode the application to use a GUI. If there is no console the doskey isn't going to get anything.
- Write some JNI that bypasses the java input handling. If you handle the input directly then you can turn off echo
- Inspect the java source code for the VM. There might be a hidden method to turn echo off. Alternatively you can find the code responsible for this, modify them, and use them with the bootclass option to replace the ones in the VM. This solution is not distributable. And it might not be possible solely using java.

How to execute dos command in Java program?

In Perl, it has System(command) to call dos command.
Does java have this thing?
or any other way to execute dos command in java program?
Because i must call javacto compile a file when the user inputed a java file name.

Look in the Runtime class, it is implemented using the Singleton design pattern so you have to use the static method getRuntime to get its only instance, on that instance you can invoke methods like
exec(String command) that will execute that command in a dos shell.

Error while running DOS command in Java

Hi all,
I use "runtime" class to execute a DOS command "copy C:\\pathname\\*.* C:\\backupPathname\\". But I saw an error msg "CreateProcess: copy C:\pathname\*.* C:\backupPathname\ error=2".
I did create a folder C:\backupPathname\ before running the DOS command.
Pls help me all Java genius.

I ended up writing a small 'c' program and pasing the command in to it from java. The problem seems to be that in dos, unlike unix, the copy command is not a program, rather the command is interpreted by the command.com program.

Does MAC OS have a "route add" command similar to a DOS command?

Does MAC OS have a "route add" command similar to a DOS command?
I know that with DOS, you can type "route add 192.168.x.x MASK 255.255.x.x 192.168.x.x" to add a route on your PC,but does MAS OS X(10.4.9) have something similar to it? I have a network printer that my winXP can access but my MAC cannot. I was unable to ping it from both wINXP and MAC. But after I added the route to my winXP I was able to ping and print to it. I do not know if I can do the same to my MAC. Does anyone know what the command is?
Thank you in advance.

Yes, and Welcome! ...

True Billy, but even Windows hasn't completely got away from using the "DOS" word...Yeah - the command line/shell environment is based on that of the old DOS command interpreter. But Microsoft does not make the mistake of call it DOS.
In fact, with earlier versions of Windows NT, a 16bit DOS real-mode virtual machine was supported. This was very kewl.
Running a large BBS with multiple nodes back then required a DOS machine per node, an IPX network, and a Novell file server.Novell Netwars. ;)
Ahhhh! good old DOS... so many good programs written at that low level, outside the Windoze environment.Yeah.. cut my teeth on writing code for DOS. Still have all my old BIOS and assembler manuals for it. Wrote my own screen s/w (write to a buffer and then move it into the video buffer, instead of writing char wise to the video buffer via interrupts), mucking about with my own concurrent threading model (using very simplistic cooperative multitasking) and so on. Heck, wrote tons of s/w on DOS... :-)Yeah I've still got a copy of my old machine code programs for writing to buffers and screen memory switching for smooth animation. Run them nowadays and they run like sh!t off a shovel. And all my old coursework including writing an interpreted language and multi-window (dos based windows) editor, parser and the code to execute the language and display the output. Oooo, and so much other stuff.
Awesome back then as you got really intimate with the o/s and hardware. This is sorely lacking today in environments like Java. And I think the reason why so much code written today is less than optimal - to put it kindly.Exactly. Started for me on the Sinclair zx81 (writing Basic), then the Sinclair Spectrum (Basic and Assembly), then Sinclair QL (yes I really had one!) and then the BBC Master 128K (where I got to writing my own rom filing system and creating my own eproms, to integrate with the word processor for additional printing features etc. as well as storing games on rom for speedy loading - and I still have it and it still works!)
It's that level of working with the underlying memory and assembly language that gives you the understanding of how values are passed between code using the stack and registers, and how memory allocation and referencing is done etc. As you say... it's missed in a lot of todays teaching, which just seems too high level and misses the basic concepts of things such as datatypes and why they are different. I bet half the modern programmers wouldn't have a clue how to do multiplication or division of binary numbers using the carry flag.
