I have console application ThirdPartyApplications.exe, that I have to run from windows service.
Console application give me reposes: OK, NOT OK and ERROR.
I need to capture these responses in my windows service.
I created function
using (var p = new System.Diagnostics.Process())
{
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = #"C:\ThirdPartyApplications.exe";
p.StartInfo.Arguments = "3";
p.Start();
string o = p.StandardOutput.ReadToEnd();
p.WaitForExit();
}
How can I capture this output?
EDIT
using (var p = new System.Diagnostics.Process())
{
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = #"C:\ThirdPartyBatch.bat";
p.StartInfo.Arguments = "file.zip -user.properties";
p.Start();
string o = p.StandardOutput.ReadToEnd();
p.WaitForExit();
}
Batch file is
#echo off
call run.bat %* 1>log\out.txt 2>log\err.txt
#echo code %ERRORLEVEL%
exit /B %ERRORLEVEL%
here, in my variable o, I do not get message "code 10"
if I have
#ECHO off
ECHO Hello
PAUSE
Here, I get message "Hello", but if I change batch file
#ECHO off
call run.bat %* 1>log\out.txt 2>log\err.txt
ECHO Hello
PAUSE
I do not get message "Hello"
Any help?
How can I capture this output?
Only when not running as a service.
An executable on Windows has to call specific APIs (directly as a Win32 application or indirectly under a framework like .NET), if it doesn't call these (eg. logic based on a command line switch1) then it is a normal executable.
When run as a service the executable is started by the Service Control Manager (SCM), and there is no access to standard output, error or input.
1 This can be useful when developing and debugging services: an "interactive" mode allowing easy running from the command line or within a debugger.

I would like to run an external .bat file using groovy script in soapUI. also would like to use the output generated from the external file as the value for the header
here is the script that I am using to run the bat file
String line
def p = "cmd /c C:\\Script\\S1.bat".execute()
def bri = new BufferedReader (new InputStreamReader(p.getInputStream()))
while ((line = bri.readLine()) != null) {log.info line}
here is the content of the bat file
java -jar SignatureGen.jar -pRESOURCE -nRandomString -mGET -d/api/discussion-streams/metadata -teyJ0eXAiOiJKV1QiLCJhbGciOiJIUzUxMiJ9.eyJjbGllbnQiOiIxIiwicm9sZSI6IllGQURNSU4iLCJleHAiOjI3NTgzMjU2MDIsInRpIjo3MjAwNiwiaWF0IjoxNTU4MzI1NjAyLCJwZXJzb24iOiI1In0.bbci7ZBWmPsANN34Ris9H0-mosKF2JLTZ-530Rex2ut1kjCwprZr_196N-K1alFBH_A9pbG0MPspaDOnvOKOjA
The following code:
def p = "ls -la".execute()
def err = new StringBuffer()
def out = new StringBuffer()
p.waitForProcessOutput(out, err)
p.waitForOrKill(5000)
int ret = p.exitValue()
// optionally check the exit value and err for errors
println "ERR: $err"
println "OUT: $out"
// if you want to do something line based with the output
out.readLines().each { line ->
println "LINE: $line"
}
is based on linux, but translates to windows by just replacing the ls -la with your bat file invocation cmd /c C:\\Script\\S1.bat.
This executes the process, calls waitForProcessOutput to make sure the process doesn't block and that we are saving away the stdout and stderr streams of the process, and then waits for the process to finish using waitForOrKill.
After the waitForOrKill the process has either been terminated because it took too long, or it has completed normally. Whatever the case, the out variable will contain the output of the command. To figure out whether or not there was an error during bat file execution, you can inspect the ret and err variables.
I chose the waitForOrKill timeout at random, adjust to fit your needs. You can also use waitFor without a timeout which will wait until the process completes, but it is generally better to set some timeout to make sure your command doesn't execute indefinitely.
I am beginning to think my search skills are lacking.
I trying to find any articles on how with Groovy, to open an interactive process, read its output and then write to the process depending on the output text. All I can find is how printing, reading and writing with files. Nothing about how to Write to a interactive process.
The process is asking for a password
Write the password to process
Something like this if possible:
def process = "some-command.sh".execute()
process.in.eachLine { line ->
if (line.contains("enter password")) {
process.out.write("myPassword")
}
}
This here works reading from the process output:
def process = "some-command.sh".execute()
process.in.eachLine { line ->
println line
}
Though it stops when the process is asking for input. It does not print out the line with the question.
Edit: Found out why it did not print the line with the ask password. It was not a new line. The question was a simple print (not println). How do I read when there is not yet a new line?
I have been told expect can be used, but I am looking for a solution which does not require a dependency.
1.bat
#echo off
echo gogogo
set /P V=input me:
echo V=%V%
this script waits for input just after :
gogogo
input me:
this means that eachLine not triggered for input me because no new line after it
however the previous line gogogo could be caught
and following script works for gogogo but does not work for input me
groovy
def process = "1.bat".execute()
process.in.eachLine { line ->
if (line.contains("gogogo")) {
process.out.write("myPassword\n".getBytes("UTF-8"))
process.out.flush()
}
}
groovy2
probably this could be optimized.. following script works without new line:
def process = "1.bat".execute()
def pout = new ByteArrayOutputStream()
def perr = new ByteArrayOutputStream()
process.consumeProcessOutput(pout, perr) //starts listening threads and returns immediately
while(process.isAlive()){
Thread.sleep(1234)
if(pout.toString("UTF-8").endsWith("input me:")){
process.out.write("myPassword\n".getBytes("UTF-8"))
process.out.flush()
}
}
I have a function as below :
function LONG ImportSSL(hMSI)
STRING exeDir;
STRING sslDir;
NUMBER nvSize;
LONG ret;
begin
nvSize = 256;
MsiGetProperty (hMSI, "SETUPEXEDIR", exeDir, nvSize);
sslDir = exeDir ^ "ssl\\myCertificate.pfx";
ret = LaunchAppAndWait(WINDIR, "certutil -f -p \"\" -importpfx \"" + sslDir + "\"", WAIT);
if (ret != 0) then return ret; endif;
return 0;
end;
by running Setup.exe as below:
MySetup.exe /v"/l*v c:\SetupLog.log"
I see the below error in log file :
CustomAction ImportSSL returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 16:25:25: ImportSSL. Return value 3.
but when I execute certutil -f -p "" -importpfx "C:\myCertificate.pfx" by command prompt there is no any error , and that certeficate imported into IIS.
How can I know the details of error?
Any help will be truly appreciated.
The problem solution will depend on the following: 1)Is certificate file being delivered by the installer, or is it supposed to be present on the target machine? Check that the installer delivers it as a permanent file, or support file (in [SUPPORTDIR]), or if the file really exists; 2) where this custom action is located? Normally actions like that should be placed after InstallFinalize.
I need to run a python script in windows system using groovy script.
Example:
python.exe c:/main.py argument1
I am new to groovy and I don't know, how to do it.
Please share me groovy syntax to run python as mentioned in the above example
I am preparing this script for jenkins.
so, "command".execute() is the right start.
But this command only starts a thread and you don't wait for the result.
try this code:
def task = "python main.py".execute()
task.waitFor()
println task.text
These lines start the execution, wait for it to finish and print the result.
To output already during execution for longer running tasks, I've written myself a small helper:
String.metaClass.executeCmd = { silent ->
//make sure that all paramters are interpreted through the cmd-shell
//TODO: make this also work with *nix
def p = "cmd /c ${delegate.value}".execute()
def result = [std: '', err: '']
def ready = false
Thread.start {
def reader = new BufferedReader(new InputStreamReader(p.in))
def line = ""
while ((line = reader.readLine()) != null) {
if (silent != false) {
println "" + line
}
result.std += line + "\n"
}
ready = true
reader.close()
}
p.waitForOrKill(30000)
def error = p.err.text
if (error.isEmpty()) {
return result
} else {
throw new RuntimeException("\n" + error)
}
}
This defines through meta programming a new method on String called executeCmd.
Put this on top of your file and then your line
"python c:/main.py".executeCmd()
This should show you all output during execution and it will help you to handle the paramaters the correcct way through the "cmd /c"-prefix. (If you just call execute on a string, you often run into problems with spaces and other characters in your command.
If you already have the parameters as a list and need some code which also runs on a *nix machine, try to call execute() on a list:
["python", "c:/main.py"].execute()
hope this helps

I'll apologise in advance, I'm new to groovy. The problem I have is I have 3 groovy scripts which perform different functionality, and I need to call them from my main groovy script, using the output from script 1 as input for script 2 and script 2's output as input for script 3.
I've tried the following code:
script = new GroovyShell(binding)
script.run(new File("script1.groovy"), "--p", "$var" ) | script.run(new File("script2.groovy"), "<", "$var" )
When I run the above code the first script runs successfully but the 2nd doesn't run at all.
Script 1 takes an int as a parameter using the "--p", "$var" code. This runs successfully in the main script using: script.run(new File("script1.groovy"), "--p", "$var" ) - Script 1's output is an xml file.
When I run script.run(new File("script2.groovy"), "<", "$var" ) on its own in the main groovy script nothing happens and the system hangs.
I can run script 2 from the command line using groovy script2.groovy < input_file and it works fine.
Any help would be greatly appreciated.
You cannot pass the < as an argument to the script as redirection is handled by the Shell when you run things from the command line...
Redirecting output from Scripts into other scripts is notoriously difficult, and basically relies on you changing System.out for the duration of each script (and hoping that nothing else in the JVM prints and messes up your data)
Better to use java processes like the following:
Given these 3 scripts:
script1.groovy
// For each argument
args.each {
// Wrap it in xml and write it out
println "<woo>$it</woo>"
}
linelength.groovy
// read input
System.in.eachLine { line ->
// Write out the number of chars in each line
println line.length()
}
pretty.groovy
// For each line print out a nice report
int index = 1
System.in.eachLine { line ->
println "Line $index contains $line chars (including the <woo></woo> bit)"
index++
}
We can then write something like this to get a new groovy process to run each in turn, and pipe the outputs into each other (using the overloaded or operator on Process):
def s1 = 'groovy script1.groovy arg1 andarg2'.execute()
def s2 = 'groovy linelength.groovy'.execute()
def s3 = 'groovy pretty.groovy'.execute()
// pipe the output of process1 to process2, and the output
// of process2 to process3
s1 | s2 | s3
s3.waitForProcessOutput( System.out, System.err )
Which prints out:
Line 1 contains 15 chars (including the <woo></woo> bit)
Line 2 contains 18 chars (including the <woo></woo> bit)
//store standard I/O
PrintStream systemOut = System.out
InputStream systemIn = System.in
//Buffer for exchanging data between scripts
ByteArrayOutputStream buffer = new ByteArrayOutputStream()
PrintStream out = new PrintStream(buffer)
//Redirecting "out" of 1st stream to buffer
System.out = out
//RUN 1st script
evaluate("println 'hello'")
out.flush()
//Redirecting buffer to "in" of 2nd script
System.in = new ByteArrayInputStream(buffer.toByteArray())
//set standard "out"
System.out = systemOut
//RUN 2nd script
evaluate("println 'message from the first script: ' + new Scanner(System.in).next()")
//set standard "in"
System.in = systemIn
result is: 'message from the first script: hello'
