For Wayland I just use this:
alias pbcopy='xsel --clipboard --input'
alias pbpaste='xsel --clipboard --output'
Switching between macOS for job and linux for everything else, I’ve honestly never realized any difference.
I'm confused; xsel, as you might imagine from the name, is very specifically a program for manipulating the X11 selection and clipboard. So it does work on Xorg, but I'm very confused that it would work in any meaningful capacity on Wayland. Are you somehow using Xwayland?
