I drop files I want to share in ~/public_html/files/
as I have a webserver running on my desktop with the firewall open to the local network. Might be tough for a noob to setup though. But on my phone the file shows up in /~christopher/files/
and I have trouble remembering how to type the tilde.
$ info {command}
although not available for all commands will often give texts that are more tutorial in nature. If you don’t like the interface of info, you can use tkinfo instead.
