How can I run cmd from batch file and add text to

Question

I want to make file.bat that should run my jar only when user press enter. Bat must run and does't execute anything without user press enter. In cmd should be printed:

java -jar crawler-1.0.jar

A part from that user could change this.text

How can I do this?

Answer 1

Try this:

@echo off
Echo java -jar crawler-1.0.jar
set /p =
java -jar crawler-1.0.jar
Echo.
pause

That way, the program will start only if the user hits enter (and not any other key). Also, the window should remain to show the output from the program.

Answer 2

You can always just echo the command, then pause before running the command, not perfect, but it works:

ECHO java -jar crawler-1.0.jar
pause
java -jar crawler-1.0.jar

Answer 3

@echo off
cls
echo java -jar crawler-1.0.jar
echo Press ENTER to continue
pause > nul
<insert command to execute here after user press a button>

1. line = standard start of batch-file
2. line = clears the screen so that only your wanted text will appear
3. line = displays the text you wanted
4. line = tells the user what to do (it will actually activate regardless of key entered; you can't choose that) [optional of course]
5. line = regular pause command - > nul does only hide the "press a key" in favour of your 4th line custom message, or no message at all
6. line = enter your desired run code

I can't comment, so answer to comment question is here:

@echo off
:start
cls
echo java -jar crawler-1.0.jar
echo Press ENTER to continue
pause > nul
<insert command to execute here after user press a button>
goto start

Answer 4

Excuse me. I think that the real goal of this question is: "How to prefill the cmd.exe command-line input with an editable string", so the user may just press Enter key to execute the prefilled input, or edit it in any desired way. I copied the method below from this post:

@if (@CodeSection == @Batch) @then

@echo off
rem Enter the prefill value in the keyboard buffer
CScript //nologo //E:JScript "%~F0" "java -jar crawler-1.0.jar"
goto :EOF

@end

WScript.CreateObject("WScript.Shell").SendKeys(WScript.Arguments(0));
