Assign the output of a command to a variable

  • 772

In linux it would be as easy as:

var = `command $url`
var = $ (command $url)

But in batch I am trying with a for but it is not taking me the content of the variable% URL%:

set URL=pagina.com:435435
for /f %%i in ('command  %URL%') do set TITULO=%%i

Does anyone know what's going on?

    The following works on a CMD command line and accomplishes assigning the output of a command to a variable.

    shell:

    set url=www.google.com
for /f %i in ('curl %url%') do set TITULO=%i

    bat or cmd file:

    set url=www.google.com
for /f %%i in ('curl %url%') do set TITULO=%%i

    Since you use a for there may be more than one value for the TITLE variable, if you want to keep them all in something like a list you can use the following:

    bat or cmd file:

    @echo off

set url=www.google.com

setlocal EnableDelayedExpansion

    for /f %%i in ('curl %url%') do set TITULO=!ListaTitulos! %%i
    
    echo !ListaTitulos!

endlocal
