Use CON to Enter Data to File

Q

How to use CON file name to enter data to a file quickly? I don't want to use any editors.

Since CON is a special file name referring to the console including keyboard, you can use it with the "copy" command to enter data to a file.

For example, if you want to create small batch file called "random.bat" with one line of command, you can try the following:

C:\fyicenter>copy con random.bat
@echo %random%
^Z
        1 file(s) copied.

Note that Ctrl-Z was pressed to terminate the input from keyboard.

Now you can the "random.bat" batch file to generate random numbers:

C:\fyicenter>random.bat
11799

C:\fyicenter>random
4390

C:\fyicenter>random
31390

⇒ Use CON to Display Data on Screen

⇐ Use NUL to Sink Program Output
