How to echo “2” (no quotes) to a file, from a batch script?

Question

How do I echo the number 2 into a file, from a batch script?

This doesn\'t work:

Echo 2>> file.txt

because 2&g

Answer 1

If you need an accurate write, use this command

(ECHO |set /p=2)>>file.txt

the command by DMan will produce a 0x0D0A line break behind the "2"

Answer 2

escape the haracter '2'

in linux: echo \2>file.txt

in windows: echo ^2>file.txt

in windows this also will work

echo.2>file.txt no space between echo and the dot

Answer 3

echo.2>>text.txt

Yes, it's weird.

Answer 4

Use (ECHO 2)>>file.txt. This will output 2 without any spaces.

Answer 5

echo ^2>>file.txt appears to work for me.

Answer 6

To write a number to a file without a trailing line-break you could use the following:

cmd /C set /A "2">file.txt

This works, because set /A returns the (last) result (without line-break) when executed in command prompt context (hence when directly run in cmd.exe).

If you are working in command prompt anyway, you could simply use this:

set /A "2">file.txt

Though you cannot use that in a batch file, you need the extra cmd /C to force the right execution context.

Needless to say, this can of course only output numbers, or precisely said, signed 32-bit integers.
