How can I suppress the "terminate batch job" in cmd.exe [closed]

I'm looking for a mechanism for suppressing the "Terminate batch job? (Y/N)" invitation that I get whenever I press CTRL-C in a program started from a batch file:

batch file: jsshell.bat:

@echo off
java -jar build-scripts\contrib\rhino1.7R1.jar

and then starting it on cmd shell by:

> jsshell.bat

which gives me a shell that can be exited by CTRL-C but after invoking CTRL-C I get a "Terminate batch job (Y/N)?" message which is nasty and annoying. How can I get it to just exit without me having to press 'y'?

FWIW, this add-on app solves the problem via a setting, and brings much more goodies. code.google.com/p/clink Can't add as answer since it's closed. – Grilled 3/4, 2013 at 6:47

Don't forget to consider working around the problem by avoiding batch scripts.

Doskey macros can replace one-liner batch scripts like the one quoted above. (Load them up in your Autorun script.)
Cscript.exe is available on every modern Windows machine and can run JavaScript and VBScript programs from the command line
If you add file extensions for your favorite scripting language (Perl, Python, Ruby, etc.) to your PATHEXT environment variable and add the script to your path, you can execute them directly without a batch script.

All good points. However I am aiming for this to work out of the box after stuff is checked out from SVN. So adding things to PATHEXT or autorun doesn't work. – Ragen 18/11, 2009 at 22:30

Your users had to install Java, right? This is just one more step. – Luminal 23/11, 2009 at 17:14

@cellcortex: Note also that VBScript is already in Pathext. – Tumbrel 16/3, 2011 at 21:2

I realize this is really old, but I found the question so here's a super helpful guide for implementing the first method listed above Doskey is to Windows as Alias is to Unix. Pretty much allows you to replicate the Unix command 'alias'. Good stuff. – Robinetta 13/3, 2015 at 6:45

At this site, I finally found an effective solution:

script.cmd < nul

To not have to type this out every time I made a second script called script2.cmd in the same folder with the line above. You may want to reverse the names. Works for me, but tested so far on XP only.

The behaviour is implemented in the cmd.exe source code, and isn't possible to turn off without modifying cmd.exe. However you can modify cmd.exe to not show the message.

holy crap that is some hard core fix. Surely there has to be a less obtrusive way? – Plucky 5/8, 2009 at 17:29

When's the last time you got your NOOP on? Okay, not such a good solution if you wanted anyone else to use. – Schnook 5/8, 2009 at 18:13

Thanks, but patching cmd.exe is something I would rather not like to do. – Ragen 16/8, 2009 at 14:23

Doesn't work on Windows 7; cmd.exe has changed substantially. – Luminal 16/10, 2009 at 21:37

@Dan Fabulich Works perfectly well on Windows 7, don't mislead people. – Lactoscope 23/5, 2015 at 21:1

Here it is - I remember I saw it somewhere - how to do it on Windows 7: axil.github.io/patching-cmdexe.html – Lactoscope 24/5, 2015 at 16:29

@Microsoft, are you listening?? – Halliehallman 25/3, 2020 at 14:52

Someone do this in official Microsoft repo, please – Milfordmilhaud 29/5, 2021 at 13:26

FWIW, piping 'N' as the input for a command worked me for some batch files (but I actually wanted the new window). Maybe it will work for you too.

(echo. N)| cmd /c java -jar build-scripts\contrib\rhino1.7R1.jar

Keep in mind that this might cause issues with languages different than English. Nice workaround though. – Lory 12/12, 2015 at 17:45

this works great at least on windows 7 – Porterhouse 17/9, 2016 at 16:5

WOW this works gread on my Win10 machine with locale FR, smart and so userfriendly as it is memorized in the history queue as the original command...compared to patching the cmd.exe... – Sri 7/2, 2017 at 22:37

this should've been the accepted answer – Bellman 3/2, 2018 at 23:54

Oh and another thing, using (echo N) (without the .) hides the ^C. – Bellman 3/2, 2018 at 23:57

Yes, there is more elegant way than patching cmd.exe. Just put START in front of your command. For your example the line would read like: "START java -jar build-scripts\contrib\rhino1.7R1.jar"

Vilipend answered 7/9, 2009 at 20:15 Comment(7)

This seems to open a new console window and run inside that. – Ragen 12/10, 2009 at 21:53

use start /B to not get get a new window – Derain 14/4, 2014 at 8:41

@JonnyLeeds you don't get a new window this way, but then another problem comes up - when you type 'exit' in the original shell window, it just won't close. – Squish 25/6, 2014 at 5:49

@Squish How intuitive! its hard to believe how terrible the windows shell is sometimes! – Derain 25/6, 2014 at 10:12

@Jonny Leeds with start /B in addition to suppressing the prompt 'Terminate batch job' and getting a new window you suppress the Ctrl-C too. – Lactoscope 24/5, 2015 at 16:24

@AntonyHatchkins nightmare. Its a while since I messed around with this, maybe it just doesn't work at all, that seems to be what egor says aswell – Derain 27/5, 2015 at 12:3

@Jonny Leeds I ended up patching cmd.exe as described in WireGuy's answer above – Lactoscope 27/5, 2015 at 17:36

@start cmd /c java -jar build-scripts\contrib\rhino1.7R1.jar
@exit

this will make only one window

Timofei answered 28/8, 2011 at 22:41 Comment(2)

It will open a new window and close the current one. Slightly different, especially since the new window won't have any of your size settings. Also, you probably meant /k since /c will close the second window when the program exits, leaving you with no windows at the end. – Khadijahkhai 20/7, 2013 at 0:7

How to add WAIT with this command? "start /WAIT CMD /K" is not working – Glyoxaline 19/10, 2016 at 10:39

The modification below suppresses "Terminate batch job? (Y/N)" and the new console window:

start cmd /c java -jar build-scripts\contrib\rhino1.7R1.jar

Chainman answered 14/10, 2009 at 11:16 Comment(4)

Opens a new console window on my machine. (I'm on win7 but I doubt that makes a difference.) – Luminal 16/10, 2009 at 21:28

Opens 2 new console windows for me – Ragen 20/10, 2009 at 21:12

Hmm, weird. The example that's working for me is for launching a GWT in hosted mode browser: start cmd /c %JAVA_HOME%/bin/java %JAVA_OPTS% -classpath %CLASSPATH% com.google.gwt.dev.GWTShell %GWT_OPTS% This launches a console window when you double click on the BAT file but - as I mentioned above - suppresses the Terminate batch job? (Y/N)" on exit and suppresses the launch of an additional console window. Maybe this "rhino" is a console app and thus must run in a console? – Chainman 21/10, 2009 at 9:1

the trick is: start /b /wait %comspec% /c java .... – Epidermis 15/7, 2014 at 19:41

Try this. It does open a new console, but it locks the other one while it's open.

@echo off
start /WAIT java -jar build-scripts\contrib\rhino1.7R1.jar
