Starting from a question on Discord
How do I send information from a live-dvd like ArcoLinuxD to the internet without browser?
The answer is install
sudo pacman -S pastebinit
To know any application in linux you type two things
pastebinit --help or -h
This will give you all the info you require.
Navigate to the log or file you want to put on the net and type
pastebinit -i README -b http://pastebin.com
Then you get a link where your data is.
