Shell Script File(.sh) does not run from c# core on linux

问题

I am trying to run ".sh" file from c# core application.But it doesn't seem to be running properly.Here is my scenario.

I am working on .Net core project which is hosted on Linux environment.We are trying to create "PDF" in our project for which we have used "Apache FOP". Here i have created one "shell script" file "transform.sh" which internally calls "fop" with required parameters.Since developement is being done on windows machine we tested the same usinf "batch" file i.e. "transform.bat",but since we cannot use the "batch" file on linux enviornment we have created shell script file "transform.sh"

Following is the code from"transform.sh"

./fop -xml $1 -xsl $2 -pdf $3

Following is C# code from which i am calling the "shell script file

    var process = new Process
                        {
                            StartInfo = new ProcessStartInfo
                            {
                                UseShellExecute = false,
                                RedirectStandardOutput = true,
                                Arguments = string.Format("{0} {1} {2}", XML_filename, XSL_filename, output)                                
                            }
                        };

    process.StartInfo.FileName = "Path to shell script file";
    process.Start();
    process.WaitForExit();

Above code doesnot give any error but it also does not create the pdf file.If i directly run the shell script file from "Terminal" it works fine and create pdf file.

 ./transform.sh "/home/ubuntu/psa//PdfGeneration/ApacheFolder/XMLFolder/test.xml" "/home/ubuntu/psa/PdfGeneration/ApacheFolder/XSLTFolder/Certificate.xsl" "/home/ubuntu/psa/PdfGeneration/ApacheFolder/PDFFolder/t444t.pdf"

Please let me know if there is something wrong i am doing?How can i make the sheel script run on linux through C# core application. Thanks.

I was able to solve the issue,just thought that i should put my solution here so that it may help others in future...

As mentioned in Question i was not able to generate the PDF file through shell script on linux machine.After debugging as suggested by "@JNevill" I came to understand that the shell script file was not getting called from .net process itself.

So my first task was to make the shell script file called through .Net Process. After lots of searching through Net and trying out different solutions i got solution at How to perform command in terminal using C#(Mono).

So changed my code of calling the process as follow,

var command = "sh";
var myBatchFile = //Path to shell script file
var argss = $"{myBatchFile} {xmlPath} {xsltPath} {pdfPath}"; //this would become "/home/ubuntu/psa/PdfGeneration/ApacheFolder/ApacheFOP/transform.sh /home/ubuntu/psa/PdfGeneration/ApacheFolder/XMLFolder/test.xml /home/ubuntu/psa/PdfGeneration/ApacheFolder/XSLTFolder/Certificate.xsl /home/ubuntu/psa/PdfGeneration/ApacheFolder/PDFFolder/test.pdf"

var processInfo = new ProcessStartInfo();
processInfo.UseShellExecute = false;
processInfo.FileName = command;   // 'sh' for bash 
processInfo.Arguments = argss;    // The Script name 

process = Process.Start(processInfo);   // Start that process.
var outPut = process.StandardOutput.ReadToEnd();
process.WaitForExit();

After changing the code ,the ".sh" file got executed and i was able to generate the PDF file.

Also script of the ".sh" file i.e. (transform.sh) which was calling Apache FOP file i.e. "FOP.sh" also needed to be changed.

Initially code was

./fop -xml $1 -xsl $2 -pdf $3

Which i changed as follow,(Change was to give full path of the FOP file)

/home/ubuntu/psa/PdfGeneration/ApacheFolder/ApacheFOP/fop -xml $1 -xsl $2 -pdf $3
