first off, I know that this question has been asked before, but I’m very technologically illiterate and I’m unable to understand the answers (and they’ve all been answered a couple years at least), so please forgive me if this is inconvenient. I’m trying to run an SCP command to remotely copy a linux directory (centOS)…Details
