lua io.popen run program with space in path












0















I'm trying to get this program to start but I keep getting an error.
I've already tried to make the blockquotes [====] around the string and "" around the program path but it still doesn't work.



local test = string.format([==["C:Program Files (x86)Audacityaudacity.exe" "F:Aufnahme %s.%s.%sZOOM0001.WAV"]==], tag, monat, jahr)

print(test)
io.popen(test)


error when running the lua file



If I copy the command from the print(test) and use that in cmd.exe it works.



Thanks for the help :)

          On Windows, you must enclose your command line (program + arguments) in additional outer-level quotes.



          local test = string.format([==["C:Program Files (x86)Audacityaudacity.exe" "F:Aufnahme %s.%s.%sZOOM0001.WAV"]==], tag, monat, jahr)

          test = '"'..test..'"'
          print(test)
          io.popen(test)


          When you are typing the command from keyboard in CMD.EXE window, then these additional quotes are added automatically by the code that is processing your keyboard input.

          When you're using C function system of Lua functions os.execute, io.popen then you must add additional quotes manually.

          This is how CMD.EXE works (and its design is full of not-very-logical decisions).
