Стандартными средствами вроде сложновато

file <input.txt >output.txt

On linux, try this: https://github.com/daveho/EasySandbox

Don't worry about "shoutdoun" command:

shoutdoun

zsh: command not found: shoutdoun

P/S: in ubuntu, user can run shutdown or reboot iff that user has permission (default, just root account has this)

You must create a file called "input.txt" and other "output.txt" int the same place that you have the program file.exe. I recommend use ideone.com or compile the program on Sublime Text, even i did not understood your question and my answer may be wrong i just want likes please :D
