Os.capture nil value

gelbi123 · October 28, 2025, 6:30am

Hi there!

I am trying to call the freesound api via

os.capture(“curl ‘https://freesound…‘“, 1)

On Linux it works fine, but when I am using
this command under Windows it doesn’t work due
to the fact that

os.capture = nil

Ok, when I look at the functions of os “capture” is not listed but the terminal
suggests it to me (see screenshot).

I will try this outputs on Linux if I have more time.

Have anyone some suggestions how to deal with that or what
causes this to work on linux but nor on win (any security things?)

Greetings
Gelbi

Maybe give this method a try instead:

Here is an example code:

github.com/Jurek-Raben/DawProject-Tool

ffx.tools.DawProject.xrnx/lib/GeneralHelpers.lua

12d76d4d3


      
          end
          
          function Helpers:prepareNameForXML(string)
            return string:gsub('[%p%c]', '')
          end
          
          function Helpers:round(number, numDecimals)
            return math.floor(number * (10 ^ numDecimals)) / (10 ^ numDecimals)
          end
          
          function Helpers:captureConsole(cmd, raw)
            local handle = assert(io.popen(cmd, 'r'))
            local output = assert(handle:read('*a'))
          
            handle:close()
          
            if raw then
              return output
            end
          
            output = string.gsub(

Ok thanks!

Tried it under LInux - it works. In the evening I will try it on win…lets see

Yep,

io.popen() works in win.

Thanks
