The OP talks about transferring from a PC to a phone (and vice versa). I have no idea how to use scp on my phone or how to move a file from my PC to my phone with scp.
Honestly, if you can teach me how to do that in less than a minute, I would (no sarcasm) really appreciate it.
where the only trick part is how Android managed storage, but it's just more letters (/data/user/0/com.arachnoid.sshelper/SDCard/<path>).
Once I found Termux I embraced it since it's a nifty linux thing straight on my phone with it's own configurable sshd and it's exactly the same as above except with a different path and lots more options.
That's fair, the duopoly on the mobile platform is such that you are only allowed to do what google or apple deigns to allow, so I suppose one must take it up with them
It also requires running a ssh server on the PC, and the even harder issue of having an externally accessible IP address that will allow ssh connections to the PC from the internet - I can do the former but I'm not entirely sure if the latter is even possible with my ISP.
