@qoomon
Both code from transfer.sh and your code return a link with a % at the end, making the link fail to open when opened by just click the link in Terminal output. I have to manually remove the % from address after pasted in address bar in a browser.
I am using zsh and add the function in ~/.zshrc. What could be the reason?

not working on bash for me from alpine or ubuntu 18.04. why? 😕
