I need to automate the following command that runs on win xp (from CMD window )

     D:\Documents and Settings\muser>  erase_disk.exe 

after 10 minutes I get the question:
are you sure to erase disk(y/n)

Is it possible by using dos xp commands to send “y” character to command line? so I will not need to wait and type “y”

  • I have tried the following but its not works

           echo y| erase_disk.exe 

other different example

     D:\Documents and Settings\muser>  scan_virus_on_my_email.exe

after 1 hour I get:

                                       proccess ended to you want to exit (y/n)

This question came from our site for professional programmers interested in conceptual questions about software development.

The question seems valid, but thought I might suggest; lots of Linux programs I know of have an option to disable confirmations so they can be automated. I don't know if yours does. (entering "erase_disk.exe /h" might give you more information) – Katana314 Jul 12 '13 at 13:24
yes but this is only example , what I want is to know if we can to auto CLI command in one line , I try many options to lunch the "y" argument in to the command line so it will be automate the proccess , but as you see I not succeed – maihabunash Jul 12 '13 at 13:31
You might want to check out the unix yes command (possibly getting the source and compiling it for dos). – user220438 Jul 12 '13 at 14:06
I am not sure if we can to it ( yes is linux/unix command ) - how to compile it to WIN ENV? – maihabunash Jul 12 '13 at 14:11
@maihabunash you get a complier and compile the code. One version of it on google code. It should be trivial to write a similar program in a scripting language present on the machine if you don't have a compiler. – user220438 Jul 12 '13 at 14:16

It's been a really long time since I've done this, but in the past to automate some things we had a Y in a text file, like y.txt, and then in our batch files had statements like:

erase_disk < y.txt

That do work on Unix/Linux, but remember to insert an <kbd>ENTER</kbd> at the end of the line – user61852 Jul 12 '13 at 13:58
how ? , if I put the "y" in y.txt how to edit the enter in the y.txt file? – maihabunash Jul 12 '13 at 14:01
@maihabunash just hit enter after the "y". I used that technique once but I just needed the ENTER, so I created a file with just a new line character. – user61852 Jul 12 '13 at 14:03
yes - I did it but still I get the question - are you sure to erase disk(y/n) – maihabunash Jul 12 '13 at 14:05
I dont sure but maybe need to create soome .bat file that send the "y" string to CLI - am I right? – maihabunash Jul 12 '13 at 14:22
