Executing cmd commands in texstudio

Question

I'm trying to execute some cmd command in textstudio. In particular i would like to create a new folder where i will put some files after compiling finishes. In "option -> build -> precompile" I add the following:

But after a while a receive the rerror Error: Command crashed: "C:/Windows/System32/cmd.exe" "mkdir out"

I have solved with: cmd.exe /C mkdir out > nul 2> nul But the command output continues to be shown.

I have changed the command with cmd.exe /C mkdir out > nul 2> nul and now works. My problem now is that the command shows the output even if redirection is used. – Marjorie

What would be the equivalent in Linux? I want to run export LC_ALL="en_US" as a user command. – Peruke
