In Windows cmd, how do I prompt for user input and use the result in another command?

I have a Windows .bat file which I would like to accept user input and then use the results of that input as part of the call to additional commands.

For example, I'd like to accept a process ID from the user, and then run jstack against that ID, putting the results of the jstack call into a file. However, when I try this, it doesn't work.

Here's my sample bat file contents:

@echo off
set /p id=Enter ID: 
echo %id%
jstack > jstack.txt

and here's what shows up in jstack.txt:

Enter ID: Terminate batch job (Y/N)?
prompt batch-file windows

Try this:

@echo off
set /p "id=Enter ID: "

You can then use %id% as a parameter to another batch file like jstack %id%.

For example:

set /P id=Enter id: 
jstack %id% > jstack.txt

You can try also with userInput.bat which uses the html input element.

enter image description here

This will assign the input to the value jstackId:

call userInput.bat jstackId
echo %jstackId%

This will just print the input value which eventually you can capture with FOR /F :

call userInput.bat

I have a little cmd I use when preparing pc to clients: it calls the user for input, and the rename the pc to that. 

@ECHO "remember to run this as admin."
@ECHO OFF
SET /P _inputname= Please enter an computername:
@ECHO Du intastede "%_inputname%"
@ECHO "The pc will restart after this"
pause
@ECHO OFF
wmic computersystem where name="%COMPUTERNAME%" call rename name="%_inputname%"

shutdown -r -f

One other way which might be interesting. You can call a powershell script from where you can do pretty much anything, and send the data bach to cmd or do other stuff with something like this.

set var=myvar; 
call "c:\input2.cmd" %var%.

Its kind of more flexible (You can send the data the same way with powershell).

So in your cmd, write this considering the ps script is in C::

PowerShell.exe -ExecutionPolicy unrestricted -Command "& {. C:\Input.ps1}"

And in your input.ps1 script, write this:

$var = Read-Host -Prompt "Your input"
Write-Host "Your var:",$var
#Do stuff with your variable
