How to input command line arguments to a dotnet c# program using bash scripts?

I have a simple c# program that expects command line input (from Console.ReadLine()) when ran. There's a lot of inputs I have to provide, so I was wondering how I could automate this process. I currently have a shell script that attempts to do this, but it's not working.
#!/bin/sh
dotnet run #run the program
1 #input first argument (this failed so I tried echo 1 instead but no luck)
# <- rest of command line inputs on each line
Not really familiar with shell scripts, and I'm not fixed on this solution if you had another solution in mind. My OS is MacOS.

OK, so what I tried was this:
I made a little mcve-Console App: (dotnet 6)
var input = Console.ReadLine();
while( !string.IsNullOrEmpty(input) )
{
Console.WriteLine("User input: {0}", input);
input = Console.ReadLine();
}
Then I made a little input.txt
This is a Text.
This is another Text.
1
2
3
This is the final Text.
and finally run.sh as follows:
#!/bin/sh
dotnet run < "input.txt"
Output was
User input: This is a Text.
User input: This is another Text.
User input: 1
User input: 2
User input: 3
User input: This is the final Text.
/bin/sh is linked to dash shell in my case.
If in run.sh you replace "input.txt" with "$1", then you can call it with ./run.sh whateveryourinputfileis.txt to make a little more flexible.

Get git result from commad using powershell and pipeline in c#

Hi I am trying to create some sort of hybrid using power shell and c# as managing tool, so simple script in powershell that checks repo status
$git_status = git status
Write-Output $git_status
Now using Pipeline and Run
using (Runspace runspace = RunspaceFactory.CreateRunspace())
{
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(powershellScript);
pipeline.Commands.Add("Out-String");
Collection<PSObject> results = pipeline.Invoke();
runspace.Close();
StringBuilder output = new StringBuilder();
foreach (PSObject obj in results)
{
output.AppendLine(obj.ToString());
}
return output.ToString();
}
But I am getting empty result, when I run script in IDE power shell result looks like for example:
Write-Host "$git_status"
On branch master Your branch is up-to-date with 'origin/master'. Changes to be committed:
(use "git reset HEAD ..." to unstage) modified: DeviceDatabase/Platforms.xml
What can i do to get that response back to c# procedure?

Write-Host will only print output to terminal, but it will not pass it to stdout. If you want to get the output - use Write-Output.
Write-Host is there to build UX: change output text color, etc. For anything else use Write-Output if you want to have your scripts as tools that can be combined to solve larger problems.
You can find a better explanation here. I'll use example code from the link to expand a little:
function Receive-Output
{
process
{
# catch input from pipe and print it in green
Write-Host $_ -ForegroundColor Green
}
}
# this will print green text, because it was passed to Receive-Output
Write-Output "this is a test" | Receive-Output
# this will print white text, because it was not passed to Receive-Output
# there's a good chance "this is a test" will already be printed by the time Receive-Output gets called
Write-Host "this is a test" | Receive-Output
Edit:
As git status prints a colorful text we can safely assume it's using Write-Host in PowerShell. Based on how Posh-Git reads git status into an object I've compiled a little example code that should solve your problem:
> $status = (git -c color.status=false status)
> Write-Output $status
This is the output I get (Windows 10, PowerShell Core 6.0):

Jenkins build blocks because of a windows form

We have a .net application where it checks whether the build is on release mode and open up a simple windows form to input the version as a pre build event. I made this form to automatically close in 10 seconds if the user does not give an input. But unfortunately, in Jenkins, the build gets stuck on this step without going forward. So my guess was since Jenkins runs on command line it waits until the user input for continue. But even when I add automatically close the form it does not continue. Is there a way to build this job without UI blocking Jenkins?

You are not using Jenkins in the optimal way. Here are a few tips to help you out:
Get rid of your windows form to increment version
Add a CommonAssemblyInfo.cs in your visual studio solution with an initial version number
Force Jenkins to increment the version automatically [described below]
Commit the file by jenkins using git publisher or using svn.exe with commit flag
Reading Version number using powershell:
param([string]$assemblyInfoPath, [string]$workSpace)
$contents = [System.IO.File]::ReadAllText($assemblyInfoPath)
$versionString = [RegEx]::Match($contents,"(AssemblyFileVersion\("")(?:\d+\.\d+\.\d+\.\d+)(""\))")
Write-Host ("AssemblyFileVersion: " +$versionString)
$version = gc $assemblyInfoPath | select-string -pattern "AssemblyVersion"
$version -match '^\[assembly: AssemblyVersion\(\"(?<major>[0-9]+)\.(?<minor>[0-9]+)\.(?<revision>[0-9]+)\.(?<build>[0-9]+)\"\)\]'
$BuildVersionNumber = $matches["major"]+"."+$matches["minor"]+"."+$matches["revision"]+"."+$matches["build"]
Write-Host ("WorkSpace: " + $env:WORKSPACE.ToString()+"\version.txt")
#[Environment]::SetEnvironmentVariable("BUILD_NUMBER", $BuildVersionNumber, "Machine")
$path = $env:WORKSPACE.ToString() + "\version.txt"
$BuildVersionNumber | out-file -encoding ASCII -filepath $path
Increment Version using powershell:
#
# This script will increment the build number in an AssemblyInfo.cs file
#
param([string]$assemblyInfoPath, [string]$workSpace)
$contents = [System.IO.File]::ReadAllText($assemblyInfoPath)
$versionString = [RegEx]::Match($contents,"(AssemblyFileVersion\("")(?:\d+\.\d+\.\d+\.\d+)(""\))")
Write-Host ("AssemblyFileVersion: " +$versionString)
#Parse out the current build number from the AssemblyFileVersion
$currentBuild = [RegEx]::Match($versionString,"(\.)(\d+)(""\))").Groups[2]
Write-Host ("Current Build: " + $currentBuild.Value)
#Increment the build number
$newBuild= [int]$currentBuild.Value + 1
Write-Host ("New Build: " + $newBuild)
#update AssemblyFileVersion and AssemblyVersion, then write to file
Write-Host ("Setting version in assembly info file ")
$contents = [RegEx]::Replace($contents, "(AssemblyVersion\(""\d+\.\d+\.\d+\.)(?:\d+)(""\))", ("`${1}" + $newBuild.ToString() + "`${2}"))
$contents = [RegEx]::Replace($contents, "(AssemblyFileVersion\(""\d+\.\d+\.\d+\.)(?:\d+)(""\))", ("`${1}" + $newBuild.ToString() + "`${2}"))
[System.IO.File]::WriteAllText($assemblyInfoPath, $contents)
$version = gc $assemblyInfoPath | select-string -pattern "AssemblyVersion"
$version -match '^\[assembly: AssemblyVersion\(\"(?<major>[0-9]+)\.(?<minor>[0-9]+)\.(?<revision>[0-9]+)\.(?<build>[0-9]+)\"\)\]'
$BuildVersionNumber = $matches["major"]+"."+$matches["minor"]+"."+$matches["revision"]+"."+$matches["build"]
Write-Host ("WorkSpace: " + $env:WORKSPACE.ToString()+"\version.txt")
#[Environment]::SetEnvironmentVariable("BUILD_NUMBER", $BuildVersionNumber, "Machine")
$path = $env:WORKSPACE.ToString() + "\version.txt"
$BuildVersionNumber | out-file -encoding ASCII -filepath $path
Usage in Jenkins:
Version Format in CommonAssembly: 1.0.0.0
After incrementing: 1.0.0.1

As Tom mentioned in the comments, you should look add the option to start your forms application with a parameter that indicates that the main form should not be shown and some magic should happen. For example, check for a "/s" and let the application run silently if it is present:
MyWinformsApplication.exe /s
Also, as Tom mentioned, a console application can still open a window and this is really useful to have in Jenkins as you can then write insightful messages to the console which will be logged by Jenkins. You can always use these at a later stage to check if something went wrong.
As an additional note - if you add Console.WriteLine() to your WinForms application, Jenkins will pick the string up and add it to the console log.

Parse into Website

I have a file (text or csv) that I generate that has a list of part numbers. I need to take this list, and download some spec sheets for these parts automatically and then print. Once on the website, I need to input the part number, then print the results. What's the best way to do this?
Okay everyone, here's what I was doing before, but it would take over an hour to process on a progress 4gl (version 9.1) database into a QAD environment v8.6e on a Unix Red-Hat server:
FNAME=`date +%y%m%d%H%M%S`
echo requiredmcpartno=$1 | lynx -accept_all_cookies -nolist -dump -post_data 75.144.##.###/specdata/specdata.asp 2>&1 | tee $FNAME | lp -d$2 >>/apps/proedi/####/ftp/log/brownart.log
grep "Unit of Issue" $FNAME | cut --delimiter=: --fields=2 | awk '{print $1}'
grep -q "PACKAGING SPEC IS OBSOLETE FOR THIS PART NUMBER" "$FNAME"
if [ $? -eq 0 ]; then
echo 0
echo nopic
exit
fi
cd /apps/proedi/####/ftp/ftpscripts
rm -fr 184.168.##.###/ 75.144.##.###/ www.google-analytics.com/ 2>&1 >>/apps/proedi/####/ftp/log/brownart.log
wget -p -m -k -K -E -H --cookies=on --post-data="requiredmcpartno=$1" 75.144.##.###/specdata/specdata.asp >/dev/null 2>&1
/apps/proedi/####/ftp/ftpscripts/printspec.sh $1 $2 >>/tmp/printspec.log 2>&1
cat /apps/proedi/####/ftp/ftpscripts/"$1".pt
rm -f /apps/proedi/####/ftp/ftpscripts/"$1".pt
>>/apps/proedi/####/ftp/log/brownart.log
rm $FNAME 2>&1 >>/apps/proedi/ford/ftp/log/brownart.log
Then printspec.sh script:
file=184.168.70.174/partandpackagingphotos/PhotoDetailsSpecdata.aspx\?p\=$1.html
if [ ! -f "$file" ]; then
echo nopic >/apps/proedi/ford/ftp/ftpscripts/"$1".pt
exit
fi
grep -q "No Pictures Available for this Part Number" "$file"
if [ $? -eq 0 ]; then
echo nopic >/apps/proedi/ford/ftp/ftpscripts/"$1".pt
exit
fi
html2ps -i .7 184.168.70.174/partandpackagingphotos/PhotoDetailsSpecdata.aspx\?p\=$1.html | lp d$2 -s
echo picfnd >/apps/proedi/ford/ftp/ftpscripts/"$1".pt
The wget command takes way to long to process in Unix. Our customer may send us a conveyance file with 150-200 parts 8-9 times a day, and we need to download all of the pictures associated with each part every time we receive parts.
I was thinking of just making a flat file(text or csv), then have the user run a batch file on their windows computer to connect to the unix server, and download the file to their computer. After this, then have either the same batch job, or an excel template or something on the windows side download the pictures and print the spec sheets to their default printer.
Sorry for not posting all of this initially.

The first thing that I would try is to break the process into two or more independent pieces and run them in parallel. The scripts above appear to take a part number as a parameter. I would guess that whatever is feeding them the part number is working from a list (the "conveyance file"?) That list would be the obvious place to make the split.
If you do it in such a way that the number of concurrent processes is configurable it should be simple to find the "sweet spot". Supposing that the list of parts to be downloaded is in a table called "part" with fields "needsDownload" and "partNum". For the sake of simplicity we will assume that partNum is an integer and that the actual part numbers needing download are randomly distributed. If you are driving this process with Progress 4GL code you might write a control program something like this:
/* control.p
*
* to run two "threads":
*
* _progres -b dbName -p control.p -param "1,2" > control.1.log 2>&1 & # 1 of 2
* _progres -b dbName -p control.p -param "2,2" > control.2.log 2>&1 & # 2 of 2
*
*
*/
define variable myThread as integer no-undo.
define variable numThreads as integer no-undo.
myThread = integer( entry( 1, session:parameter )) - 1. /* this just allows the "1 of 2" stuff to be more "human sensible" */
numThreads = integer( entry( 2, session:parameter )).
for each part exclusive-lock where needsDownload = true and (( partNum modulo numThreads ) = myThread ):
os-command value( "getpart.sh " + string( partNum )).
needsDownload = false.
end.
Of course the problem might be that the external system is too slow. No amount of programming on your end will fix that.

Batch to copy files to another folder with breaks

I need a script, prefferably a windows batch or C# to do as following:
Show a prompt that first ask for the source folder,
then it should ask for the destination folder. At last, it shall ask how many files it should copy to the destination, from the source.
// We talk about aprox 100.000 files and they can be moved in random order.
After the process has been run, the program shall make a break of 10 minutes, then loop the process it was told to earlier, by previous answers to the prompt.
I've tried a little, but haven't found a solution. As far as i can see, XCOPY is unable to work around all these criterias.
Thanks in advance,
Mark

RoboCopy (the See also section might interest you as well) or
(more recent:) RichCopy (download)

You can use something like this:
string source = Console.ReadLine();
string destination = Console.ReadLine();
int numberOfFilesToCopy = int.Parse(Console.ReadLine());
DirectoryInfo di = new DirectoryInfo(source);
var files = di.GetFiles();
for(i=0;i < math.Max(files.Length, numberOfFilesToCopy);i++)
{
files[i].CopyTo(destination);
}

In C# using System.IO.File.Copy(sourceFileName,destFileName) followed by a System.IO.File.Delete(path) will do the "move" for you. You can create a simple console app that takes in the information you need and then does the work.
Have a look at the docs for System.IO.File for more info on File operations.

I'm not sure this fulfills all your requirements, but it may be useful to have a look at robocopy (robocopy /? in the command line).

Don't think I missed anything =D
