How do I copy a file to the clipboard with the terminal?

I'm aware of how to copy the **contents** of file:

xsel -b < myfile.txt

But this is **not** what I want. I would like something like this:

./file2clip.sh myfile.txt

Which would copy myfile.txt to the clipboard so then I could ctrl + v (paste) or right click and paste **the file** anywhere (on the desktop, in the file explorer, etc.). How can I copy a file/files to the clipboard so that I can paste it with ctrl + v anywhere in the gui? Windows equivalent: (powershell)

Set-Clipboard -Path myfile.txt

Macos equivalent: (applescript)

#!/usr/bin/osascript
on run args
    set the clipboard to POSIX file (first item of args)
end

./file2clip.applescript myfile.txt
