IS there an easy way to execute a shell command and capture its output...

From an application? I am thinking of using fork and then waiting for the PID to finish and write the output to a file which I then read, but this seems clunky. Also there are big warnings about frameworks getting hosed if you use fork, although the "Forked" process will exec the shell command and the one that gets the PID the original process might be 'safe' from this framework corruption. I am not certain of this, it is just a guess.
If there was something like a process class where I could specify the executable and parameters, and read from it's std out until the process completed, that would be better. Or even get a callback when the process exited and an asynchronous callback for each line of data it produced.

That was just in response to OrangeKay implied accusation that I was some kind of hard-core Microsoft programmer that sneered at apple programmers.
You may want to book mark this, I will go over a brief history which should clear a lot of things up, about me, and about what I am doing.
Lets turn the clock back to 1998: I graduate from a university with a BS in Computer science. I had been interning at a local defense contractor writing missile testing software. This was on a proprietary hardware and so there was no "Microsoft" involved. At this point I think Bill Gates = Satan. Microsoft = Kingdom of Evil.
I get a job as a video game programmer. I write code from the Playstation, then the Playstation 2 and Gamecube. I do this for several years and again I have zero interest / knowledge of the Microsoft world beyond it being the OS which I am forced to use to play my games on. I had fought this by trying to use OS Warp and other things, but eventually since I mainly had a PC for games I had to get a windows OS, the first being NT 3.51 and then Win98 cause NT4.0 didn't support past directx 3 and everyone was using directX 5 or 6 (I do not remember).
As video game companies go, they do not last. Everyone wants to write video games, anyone with some cash wants to start a company. 1 in 1000 will make it 5 years. Needless to say, as our company began to tank, I got laid off, along with my entire team. I have cash in the bank, no big deal, right?
Well the economy started to suck, video game developers were closing down like crazy so the market was saturated with x-video game developers. 2 Years go by, no job, and almost no money. Then I get a call from some guy who wants me to come for an interview about 75 miles away. It is in a place I do not want to go. So they interview me, and ask me a bunch of general programming questions.
I leave the place, and by the time I get home there is a message on my machine asking me if I would take the job at a ridiculously high salary (I live in an area where the cost of living is very low). Well I am about out of money and its a job offer with a huge salary, so I take it.
I get there and guess what? I get to work on this "agent" that runs on windows boxes. I have NO IDEA how to program on windows. Windows is evil, why would I want to taint myself with this vile Microsoft APIs? I really have no choice, I have to learn how to develop on windows. I get to use visual studio 6, which I do not understand because I used the Borland compilers (Borland != Microsoft).
Well I start to slug through it all and get familiar with MSDN and CodeProject and CodeGuru. As the years pass, I begining applicate the examples and detailed documentation that MSDN has. I have a start page on MSDN which covers every category of operation which will take you through a tree of choices and lead you to the exact area related API calls you will need to use to do whatever you want. Now I do not think MS = Evil anymore. I switch to DevStudio 2005 which is really nice. The debugging, IDE, and everything is great.
Now the other half of this application resides on a server. That server is a Linux box, and the server app is written in Java. My stuff is still C++.
One day, I get a request, and a eMac with 10.4 PPC to make a Mac version. Now I am at the point of Mac programming as I was with Windows when I started. I didn't know anything about it. I was looking for CodeWarrior cause I used that in the past, but alas, CodeWarrior is no more. I get XCode. I see all sorts of options to make a project. BSD project, Carbon, Cocoa, etc... What the heck any of these. I can guess the BSD one is very basic, but I do not understand Carbon vs Cocoa.
So what do I do? I make a basic carbon app and make a basic Cocoa app. The carbon app looks like some kind of C++ framework. The Cocoa app? "Is this another language like Java or C#? It doesn't look like a C++ language."
Guess which choice I make. Carbon. I struggle through this looking at the docs, posting on CodeGuru and whatnot until someone finally tells me about these forums and warns me about how unfriendly people are. So I make an account and start asking questions. I eventually get my app to be multi-platform to run on windows and Mac by using some API abstractions which are easy to do since I had abstracted the Windows API by my own class wrappers.
I ask a lot of questions, very few are ever answered because I am not asking about simple things, like making windows and how to get button clicks and that stuff. I am asking stuff like, "How do you change the DNS? or How do I know when a user is about to log out?" Currently on my side list as I type this, I have 27 unresolved questions. I probably found workaround for most of them, or figured it out eventually.
On this forum mostly people are helpful when the do respond, except for OrangeKay. He definitely has a chip on his shoulder.
Over the past few years my Opinion of MS has improved greatly while my opinion of Macs (from the programmer's point of view) has dropped considerably. XCode still isn't as good as VS6 which is like 15 years old, never mind Dev studio 2005 or 2008. The documentation is scattered, not easy to find, occasionally wrong, or simply missing. The examples may not even compile or contain non-existent functions. It is unbelievable how bad it is.
If Steve Jobbs wants to really get a large coder population he ought to spend some of those billions (or is it trillions) of dollars on a team that will re-write the current documentation in a correct, easy to understand, with full examples, arranged in a logical manner for everyone to use. He should say, "See MSDN online? I want something like that, only better, it has to be MUCH better." Then he should say to the XCode team, "Look at DevStudio 2008. XCode should do EVERYTHING that does. Once that is done, IMPROVE XCode even more to make 2008 look like a joke."
To bad the Developer aspect of the "Apple Experience" has not gotten "End User" treatment. Then it would be a joy to develop on Macs.
So here I am asking for help on certain things. You wonder why I do not use Cocoa. Maybe I should, maybe I shouldn't. My first look didn't look promising, and a quick look at the docs is all about GUI's. My app has NO GUI. Again, Cocoa? Maybe it will still work, but the examples and stuff I see are all about GUIs.
When I get time, I will look at cocoa even further. MFC on windows is MOSTLY about GUI stuff, but there is a small section of it that does not deal with GUIs. CString is a great MFC class. I had to get rid of it though cause Mac's do not have a similar class. I use CStdString which is a platform agnostic CString replacement.
I hope you are all a little more enlightened. BTW my Application which runs on Mac's and PCs on no less then 3 MILLION Machines has not crashed ONCE in the past 2 years. There have been bugs, but nothing that crashed it. The bugs were mostly unforeseen situations, like what if the guy has 15 network adapters that are all LIVE? I didn't plan for that, there were complications, the server got some strange data, but it didn't crash (My app, not the server. It crashes on occasion still). Are there bugs in my code? I am sure there are, but I do not know of any, because if I did, it would be fixed.

Execute dir command and get output

Hi,
Is it possible to execute a command such as dir,md or copy using a java prorgam.Plz tell me how to do this.
Thanks a lot,
Chamal.

You can get that dir info from java.io.File.listFiles(), of course.
But if you just want to run OS commands you can do it with java.lang.Runtime:

Having trouble in running a unix command and getting the output

Hi,
I am trying to run a unix command from within the java code. I am not able to make it work. I am enclosing the code and the error message that I am getting. Any help is highly appreciated.
import java.io.*;
public class RunCommand {
    public static void main(String args[]) {
        String s = null;
        try {
            Process p = Runtime.getRuntime().exec("cat UNIX_ASCII_TEXT_FILE | A_UNIX_PROGRAM -d");
            BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
            BufferedReader stdError = new BufferedReader(new InputStreamReader(p.getErrorStream()));
            // read the output from the command
            System.out.println("Here is the standard output of the command:\n");
            while ((s = stdInput.readLine()) != null) {
                System.out.println(s);
            // read any errors from the attempted command
            System.out.println("Here is the standard error of the command (if any):\n");
            while ((s = stdError.readLine()) != null) {
                System.out.println(s);
            System.exit(0);
        catch (IOException e) {
            System.out.println("exception happened - here's what I know: ");
            e.printStackTrace();
            System.exit(-1);
}The error message that I am getting is
Here is the standard output of the command:
SLu|%%$$=
Here is the standard error of the command (if any):
cat: cannot open |
cat: cannot open A_UNIX_PROGRAM
cat: cannot open -dLooks like the cat command is working and not the pipe command and the command after the pipe. But when I run the UNIX command from the command prompt I get the expected result.

You might read this article and see if its approach works.

Calling the standard program in program and getting its output in int table

Hi there,
I have a requirement, where I need to call the standard program (of transaction CJI3) in my Y program. CJI3 transaction produces a ALV GRID output. I need to use that data for further processing. I am getting following problems:
1. I tried to use SUBMIT ... EXPORTING TO MEMORY statement. I need to pass the company code for the selection, but the company code is in the dynamic selection. So not getting how to pass them.
2. Just a doubt. Can we export the ALV GRID to the memory an retrieve it back using import?
3. I did tried to use SUBMIT ..... statement using only the parameters which are on the selection screen. However the control went to CJI3 transaction and gave an error message 'Please select "from database" or "from archive" '. Did not understood that, any IDEA?
Or is there any other way with which I can accomplish my requirement of getting the data in my program to manipulate, other than SUBMIT.
Points will be rewarded.
Thanks,
Ganesh Khumse

Hi,
point 1:
SUBMIT ... EXPORTING TO MEMORY will never work, because it displays the information in an ALV grid and that grid is waiting for user interaction for manipulating the information.
point 2:
no, you cannot export the content of an ALV grid to the memory
point 3:
must you get records in an internal table or must you feed the transaction, so that this one performs a task ?? for first option read below and for the other option you might work with BDC and Transaction Recorder.
what you have to do is read the code of transaction CJI3 in order to understand what it does, where the information is read from and what is the internal table that passes the values to the ALV Grid. You might find a user exit in the code for manipulating that information or you might create an enhancement point if there´s no user exit.

How to execute some code in command line, and read its output?

I'v found here http://www.sap-advisor.com/abap-coding/how-to-execute-operating-system-commands-from-within-sap/ that I can execute commands from the windows command line for example inside SAP.
But I want to take it one step further and read its output. is it possible?

Hi RagnaRock,
one possible approach can be outputting the results of the command into a text file (i.e. "command >result.txt"), and then read this file from SAP/ABAP.
I hope this helps. Kind regards,

How to execute Linux command from Java app.

Hi all,
Could anyone show me how to execute Linux command from Java app. For example, I have the need to execute the "ls" command from my Java app (which is running on the Linux machine), how should I write the codes?
Thanks a lot,

You can use "built-in" shell commands, you just need to invoke the shell and tell it to run the command. See the -c switch in the man page for your shell. But, "ls" isn't built-in anyays.
If you use exec, you will want to set the directory with the dir argument to exec, or add it to the command or cmdarray. See the API for the variants of java.lang.Runtime.exec(). (If you're invoking it repeatedly, you can most likely modify a cmdarray more efficiently than having exec() decompose your command).
You will also definitely want to save the returned Process and read the output from it (possibly stderr too and get an exit status). See API for java.lang.Process. Here's an example
java.io.BufferedReader br =
new java.io.BufferedReader(new java.io.InputStreamReader(
Runtime.getRuntime().exec ("/sbin/ifconfig ppp0").
getInputStream()));
while ((s = br.readLine()) != null) {...

Your code is probably good to run a program, that does not use terminal capabilities.
Program "top" is a little bit more complicated - you have to run it with a real terminal.
Try to run "xterm -e top". You can find an example how to run an external program
from java code in cnd/gdb module on http://cnd.netbeans.org
For example, take a look at openExternalProgramIOWindow() method on this page:
http://cnd.netbeans.org/source/browse/cnd/gdb/src/org/netbeans/modules/cnd/debugger/gdb/proxy/Attic/GdbProxyCL.java?rev=1.1.2.6.2.5&only_with_tag=release551_fixes&view=markup
It runs a command with external terminal.

Execute Linux Command via JSP

How can I execute Linux commands through a JSP page on a Red Hat Linux 6.1 Machine using Tomcat 3.0
Please Mail your answer
[email protected]

Hi Nick,
Thankx a lot, for suggestion,
I wanted to make a page which gives me a text box to write a command and below it shows the result of that command,
Say , I m in directory "/home/dhiraj"
and I write in command text box : "pwd"
it should give me the currrent path in result , which I can show in form of HTML as Results ,
(may be in a String form..)
same way if I write in command box : "ls -l"
it should Return me (say a String) the directory listing of the current path in result,
I have already tried the Runtime & Process class ,
Runtime rt = Runtime.getRuntime();
Process p =null;
p = rt.exec("command here");
p.waitFor();
it has following problems:
1) This way I m not able to get the result ..
2) I tried to make a zip file via my program it did not threw any exception , but could not execute...
I was confused is it 'coz of permission ( rights problem) or some programmatical error as the same program runs via a Java Class file ..
desperately waiting for ur suggestions

Jarred swing app and getting console output

Hi,
I've created a jar app using eclipse that starts a swing application. The jar works fine, but I was curious if there was a way to double-click the file and get console output as well. When I start the program through the command line, I can get my output, but double-clicking the icon doesnt' start up a console. Is there a way to accomplish this?
Thanks

Normally in Windows systems the javaw executable is assigned to the jar extension. javaw is a jvm without console. You might want to change that and assign java to jar but be aware, that this affects all jar files.
If you want to do that just for that jat file I would write a bat file which starts the application using java.

Need to execute Linux Commands in JSP

I think you might need the java 'robot' class.
However, a JSP page displayed on a browser is running in a secure enviornment that will probably not let you access the computer its running on. Instead, create a serlvet back on the server that runs the robot class. The servlet will send the data to the jsp page for display. The jsp page can send commands to the servlet which will execute it via its robot class.

Executing external command and program in background

Hi,
how to execute external command and external program in background.
please provide me some tips on the same.
while creating external command, what is the significance of "operating system command" and "parameters for operating system command".
Thanks,
Dinesh.

Hi,
You can define external commands using transaction code SM69.
External commands are commands which would be executed at your operating
system with or without parameters.
Operating system commands are those which you execute at OS level like
mkdir, cat, rm, cp, ls
Parameters are options that you add to os commands to get more functionalities.
like, < ls -l > : will give you a long listing of files where " l " is the parameter
< ls -lt > : will give you a long listing with last changed file at top where " lt " is the parameter.
You can mention these in SM69 when you define the external commands.
Now, in order to execute these in your background job. In the steps click on "external command" and give your command name in SM36 while creating your job.
" Points for solution ".
Thanks and Regards,
Sandeep.
