push/pop echo state

[Václav Zeman]

Hi.

I would like to push/pop echo state similar to what `setlocal` and `endlocal` does for environment variables. Is this reasonably easily possible?

You can launch a child CMD instance, change the ECHO state to suit that
instance and when it exits the ECHO state of the original instance will
be restored. Here are two batches to demonstrate.

::This is Demo1.cmd
@echo off
echo this is %~nx0 and ECHO is OFF
cmd /c Demo2
echo control returned to %~nx0 but ECHO is still off
pause



::This is Demo2.cmd
echo control passed to %~nx0 and ECHO is ON
dir
echo this is %~nx0 and ECHO is ON

or set a variable


rem on
echo on
set noecho=off
...


rem off
echo off
set noecho=on


rem toggle
echo %noecho%
if %noecho%==off set noecho=tmp
if %noecho%==on set noecho=off
if %noecho%==tmp set noecho=on


(untested)

Hi,

it's a bit tricky to get the current echo state.
It can be done with a temp file.

Try a look at "restore the previous echo status"
