Use spawn-related function, and avoid capturing output instead. Not sure
if you need to call spawnShell (which creates a new system shell to
execute the command), it depends on whether cls is a shell builtin or an
executable.
Unsolicited spelling correction: no 'i' in "deprecated".
What's going on? The docs say that it creates a new process. I simply
want to clear the console!
`system` directly prints its output, `executeShell` returns it in a
tuple with the status code. Maybe cls works by printing some specific
clear code. If so, you have to print the output of the command.
Perhaps not exactly correct, but close enough. When you call
"executeShell", the subprocess is started with stdout/err sent to a
pipe, and no console is passed to the subprocess. Probably cls sees it's
not talking to a console and exits.
