Running 5 commands using array elements and waiting between?

Hi All,
Trying to learn PS so please be patient with me ;)
System: PSv3 on Win2012 server running WSUS role
I am wanting to execute 5 commands using a 'foreach' loop but wait until one finishes before moving onto the next. Can you please check out what I have and provide some suggestions of improvement? or scrap it completely if it's rubbish :(
Current code:
#### SCRIPT START ####
#Create and define array and elements
$Array1 = @(" -CleanupObsoleteComputers"," -DeclineSupersededUpdates -DeclineExpiredUpdates"," -CleanupObsoleteUpdates"," -CleanupUnneededContentFiles"," -CompressUpdates")
#Run the cleanup command against each element
foreach ($element in $Array1) {
Get-WsusServer | Invoke-WsusServerCleanup $element -Whatif
#### SCRIPT END ####
I am assuming that I need to use @ to explicitly define elements since my second element contains two commands with a space between?
The cleanup command doesn't accept '-Wait' so I'm not sure how to implement a pause without just telling it to pause for x time; not really a viable solution for this as the command can sometime take quite a while. They are pretty quick now that I do
this all the time but just want it to be future proof and fool proof so it doesn't get timeouts as reported by others.
I have found lots of code on the net for doing this remotely and calling the .NET assemblies which is much more convoluted. I however want to run this on the server directly as a scheduled task and I want each statement to run successively so it
doesn't max out CPU and memory, as can be the case when a single string running all of the cleanup options is passed.
Cheers.

Thank you all for your very helpful suggestions, I have now developed two ways of doing this. My original updated (thanks for pointing me in the right direction Fred) and Boe's tweaked for my application (blew my mind when I first read that API code
Boe). I like the smaller log file mine creates which doesn't really matter because I am only keeping the last run data before trashing it anyway. I have also removed the verbose as I will be running it on a schedule when nobody will be accessing it anyway,
but handy to know the verbose commands ;)
Next question: How do I time these to see which way is more efficient?
My Code:
$Array1 = @("-CleanupObsoleteComputers","-DeclineSupersededUpdates","-DeclineExpiredUpdates","-CleanupObsoleteUpdates","-CleanupUnneededContentFiles","-CompressUpdates")
$Wsus = Get-WsusServer
[String]$Logfile = 'C:\Program Files\Update Services\LogFiles\ArrayWSUSCleanup.log'
[String]$Logfileold = 'C:\Program Files\Update Services\LogFiles\ArrayWSUSCleanup.old'
If (Test-Path $Logfileold){
Remove-Item $Logfileold
If (Test-Path $Logfile){
Rename-Item $Logfile $Logfileold
foreach ($Element in $Array1)

Write-Output "Performing: $($Element)" | Out-File -FilePath $LogFile -Append -width 100
. Invoke-Expression "`$Wsus | Invoke-WsusServerCleanup $element" | Out-File -FilePath $LogFile -Append -width 100

Run shell commands using java program

Hi guys,
I am trying to run shell commands like cd /something and ./command with arguments as follows, but getting an exception that ./command not found.Instead of changing directory using "cd" command I am passing directory as an argument in rt,exec().
String []cmd={"./command","arg1", "arg2", "arg3"};
File file= new File("/path");
try{
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec(cmd,null,file);
proc.waitFor();
System.out.println(proc.exitValue())
BufferedReader buf = new BufferedReader(new InputStreamReader(proc.getInputStream()));
catch(Exception e)
{e.printStackTrace();
So can anyone please tell me what is wrong with this approach? or is there any better way to do this?
Thanks,
Hardik

What gives you the idea that the process to execute is called "./command"? If this is in Windows, it is "cmd.exe" for example.It does not have to be cmd.exe in Windows. Any executable or .bat file can be executed as long as one either specifies the full path or the executable is in a directory that is in the PATH.
On *nix the file has to have the executable bit set and one either specifies the full path or the executable must be in a directory that is in the PATH . If the executable is a script then if there is a hash-bang (#!) at the start of the first line then the rest of the line is taken as the interpreter to use. For example #!/bin/bash or #!/usr/bin/perl .
One both window and *nix one can exec() an interpreter directly and then pass the commands into the process stdin. The advantage of doing this is that one can change the environment in one line and it remains in effect for subsequent line. A simple example of this for bash on Linux is
import java.io.OutputStreamWriter;
import java.io.Writer;
public class ExecInputThroughStdin
    public static void main(String args[]) throws Exception
        final Process process = Runtime.getRuntime().exec("bash");
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getErrorStream(), System.err)).start();
        new Thread(new PipeInputStreamToOutputStreamRunnable(process.getInputStream(), System.out)).start();
        final Writer stdin = new OutputStreamWriter(process.getOutputStream());
        stdin.write("xemacs&\n");
        stdin.write("cd ~/work\n");
        stdin.write("dir\n");
        stdin.write("ls\n");
        stdin.write("gobbldygook\n"); // Forces output to stderr
        stdin.write("echo $PATH\n");
        stdin.write("pwd\n");
        stdin.write("df -k\n");
        stdin.write("ifconfig\n");
        stdin.write("echo $CWD\n");
        stdin.write("dir\n");
        stdin.write("cd ~/work/jlib\n");
        stdin.write("dir\n");
        stdin.write("cat /etc/bash.bashrc\n");
        stdin.close();
        final int exitVal = process.waitFor();
        System.out.println("Exit value: " + exitVal);
}One can use the same approach with Windows using cmd.exe but then one must be aware of the syntactic differences between commands running in .bat file and command run from the command line. Reading 'help cmd' s essential here.
The class PipeInputStreamToOutputStreamRunnable in the above example just copies an InputStream to an OutputStream and I use
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
public class PipeInputStreamToOutputStreamRunnable implements Runnable
    public PipeInputStreamToOutputStreamRunnable(InputStream is, OutputStream os)
        is_ = is;
        os_ = os;
    public void run()
        try
            final byte[] buffer = new byte[1024];
            for (int count = 0; (count = is_.read(buffer)) >= 0;)
                os_.write(buffer, 0, count);
        } catch (IOException e)
            e.printStackTrace();
    private final InputStream is_;
    private final OutputStream os_;
}

First of all, I would have to say that getting in touch with you is a nightmare and I am not at all happy that I can't just email or live chat with someone who can help! I am not a technical person, I just want to be able to use Photoshop Elements and get on with it. I bought Photoshop Elements via Amazon some months ago and it worked fine. I then got a message that advised that the trial version would expire, which it subsequently has (I have been trawling your site for weeks and weeks trying to find an email or phone contact to get some assistance). Relucltantly, I am now typing this - and I suspect it will not help in the slightest! I bought the FULL not TRIAL edition of Photoshop Elements and I have contacted Amazon who confirmed this, but say I need to contact you. Can you please let me know how I can resolve this?

Running unix command using java shows error

Hi All,
I am trying to run UNIX move command using Java exec method but its throwing error, unable to rename. Here below is the code i am trying to run to move all files from one directory to another directory. source and destination directory exists.
public class Demo
    public static void main(String args[])
        try
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("mv /home/demo1/* /home/demo2");
            int exitVal = proc.waitFor();
            System.out.println("Process exitValue: " + exitVal);
        } catch (Throwable t)
            t.printStackTrace();
}if i give "mv /home/demo1 /home/demo2" in exec method, its working, with * character its giving problem.
Please help me in resolving the problem.
Thank you

Characters like *, >, &, |, etc. are interpreted by the command shell--that is by the bash, zsh, etc. programs. When you execute a command with ProcessBuilder or Runtime.exec, you're not going through one of those shells, so their interpretation of those characters is not available.
In your code, the character * is being delivered directly to the mv command (which doesn't think * is anything special), as opposed to being turned into a list of files and directories as it would be when it's interpreted by the shell. The mv command doesn't know anything about the * character being special.
If you want to have those shell interpretations, you need to execute the command through a shell. One example is like so, but a) you'll want to read up on the methods in exec() that take arrays of String, and b) you'll want to read up on ProcessBuilder, and c) you'll need to check your shell's man pages to see the exact syntax and arguments.
runtime.exec("/bin/bash -c 'mv x/* y'");

Problem in running system commands using Runtime()

hi,
i am trying to run the "dir" command in windows OS using Runtime(). But while
executing the program i am getting
java.io.IOException: CreateProcess: dir error=2 error. But if i replace the "dir" command by "notepad" command its working fine. below is the source code.
class testing
public static void main(String args[])
     try{
Runtime rt=Runtime.getRuntime();
Process p=rt.exec("dir"); //Generating Errors
//Process p=rt.exec("notepad"); //Working Fine
     }catch(Exception e){System.out.println(e);}
}plzz help me out.
thanx

thats fine its working. i made two changes. First i used an array to send the
arguments. if we directly use "cmd.exe /c dir" then its converting "/C" to "\C" thus
producing the error. so i used
Runtime rt=Runtime.getRuntime();
String args1[]={"cmd.exe","/C","dir"};
Process p=rt.exec(args1);But then i got no error no output. From other forums i came to know about capturing the data using input streams and i included the following code.
BufferedReader Resultset = new BufferedReader
     (new InputStreamReader(p.getInputStream()));
String line;
while ((line = Resultset.readLine()) != null)
     {          System.out.println(line);          }Now its working fine. Thanx for ur help.

Running System commands using Runtime.exec()

I'm trying to run an example from "The Java Programming Language" book by Arnold, Gosling and Holmes. I'm trying to run a system level command and get the results. The code looks like:
public static String[] runCommand(String cmd) {
String[] outputData= null;
String[] cmdArray = {"/usr/bin/ls", "-l", "/tmp"};
try {
Process child = Runtime.getRuntime().exec(cmdArray);
InputStream in = child.getInputStream();
InputStreamReader reader = new InputStreamReader(output);
BufferedReader = new BufferedReader(reader);
// read the commands output
int counter = 0;
String line;
while ((line = input.readLine()) != null)
outputData[counter++]= line;
if (child.waitFor() != 0){ // error when it's not 0
System.out.println("Couldn't run the command.");
System.out.println("It produced the following error message : " + child.exitValue());
outputData = null;
} catch (Exception e){
System.out.println("It got here!");
System.out.println("It produced the following error message : " + e.getMessage());
outputData = null;
return outputData;
It gets to the while line, trys to run the input.readLine() and kicks out the exception that looks like:
It got here!
It produced the following error message : null
I know it gets to the input.readLine() because I had a whole lot more try blocks in there, but for simplicity left it out (so it look like the code in the book, which I tried originally). When I run the same command from the command line (on our Sun Solaris 2.8 system) I get results back. I'm not sure what I'm doing wrong. Any help would be greatly appreciated. Thanks.

String[] theCommand = {"csh", "/export/home/gls03/sasstuff/runsas.csh", "/export/home/gls03/sasstuff/gary2.sas"};
These generate the same error. I'm thinking this is a sas-specific problem.
Thanks for any help. Gary

Running OS command using DBMS_PIPE

Hi,
I have reproduce the exemple in the documentation DBMS_PIPE - Example 3: Execute System Commands using the proc daemon.pc. It works, the commands are getting executed, but I have no control over them. What I need is for the calling PL/SQL function to wait for the OS command to finnish before continuing with the execution the PL/SQL function.
Any hint would be appreciated. Thanks.

1) generate a corrective action which is not happening (note that on line 2 above it seems like a corrective action was initiated but i don't know how this happened and this is the only occurrence)
2) run an OS command when the alert is initiated to
Questions:
1) why is the system not generating any corrective actions
2) how can i set OEM to run an OS command
Thank you for your help

On 10g+ I'd definitely give this a go.

Run dos command that starts program and program stay open

I'm running the following code,
string m_file= "c:\program\program.exe" ;// runs a program
Process myProcess = new Process();
myProcess.StartInfo.FileName = @programtextBox.Text.Trim();
myProcess.StartInfo.Arguments = m_file;
String m_arguments = myProcess.StartInfo.Arguments.ToString().Trim();
myProcess.Start();
It works fine except I need the program to stay open that this command starts. But it closes while it's in the process of starting.

I had a mistake in what I posted in my code. Here it is again with corrections, and more detail.
string m_run= "c:\my programs\adobe\photoshope.exe" //This is saved in the program and can be set to any program the user wants to use. it's saved in the programtextBox.Text noted eailer, which is saved to the hard drive.
string m_file= "c:\file\anypicture.jpg" ;// picture that is selected in the interface.
Process myProcess = new Process();
myProcess.StartInfo.FileName = m_run;
myProcess.StartInfo.Arguments = m_file;
String m_arguments = myProcess.StartInfo.Arguments.ToString().Trim();
myProcess.Start();
This is a windows form program.
It looks to me like you're either redacting or modifying your actual code before posting. I could be wrong about that, but I'm pretty sure because:
If you were calling Process.Start() against program files/adobe/photoshope.exe I believe that you'd get a Win32 Exception since I don't think that file exists in any photoshop installation.
I sincerely doubt that you're actually working with "file/anypicture.jpg."
I'm confused by the declaration of m_arguments which is never used. I assume it is in fact used somewhere in your code.
Finally, you have stated that the program to open files with is pre-defined, so I suspect that data is actually being pulled from a variable instead of from a hard string as in your "example."
If that's the case then you might as well go shoot yourself in the foot, since that would do exactly as much good as asking for help with broken code and then posting pseudo-code instead of what doesn't work. It's like telling an auto mechanic your
car dies every time you hit 22 miles per hour, while delivering your bicycle for service.

Running System Commands using Java

HI,
I am developing an application using java which requires some system commands to be run.For example i have to write a java function which can program the windows scheduler to run a particular executable at some time & another one to initiate an ftp.I however do not know how to execute the corresponding commands from java.Is there any way or some specific api(similar to the system command in c) that i can use to perform these operations.I am using j2sdk 1.4.0_01 on a win 98 machine to develop the application.

See [url http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html]java.lang.Runtime

          } catch (Exception exp) {
               exp.getMessage();

I would expect error messages to be output on stderr not stdout and you only read stdout. You should read, digest and implement the recommendations in http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html .
