Question

I have made a batch file that call another one program.bat, the first batch do its commands and then call the second one program.bat like this,

    @echo off
    bla bla bla
    ....
    ...
    ...
    call program.bat

But in this way, it will execute the second bat showing its output, however I want it to hide the program.bat output and show instead the phrase please wait ...and when program.bat finish his job, I want the first bat to return to do its other commands

Answer 1

Use:

echo Please wait ...
call program.bat >nul 2>&1

the >nul redirects standard output of program.bat to nul (to nothing), meaning it is not displayed. 2>&1 redirects other errors (yes, they are considered a different output) to the standard output, which is redirected to nul.
