I updated the function to depend on a clipboard manager:

• gpaste in this case because it keep last entries active.
• Reasons: xsel/xclip both function by running in the background and waiting to be called for pasting or clearing, the proccess try to stay even if you close the tty.
• It was hanging the closing of my tmux session and I could not open a new one with the same unit name without killing it manually.

Now it clears xsel after using it because gpaste keep the selection, and I clear gpaste history with a key binding manually when I want.

Note: GPaste does not require Gnome, it can be built light :

meson setup -Dbash-completion=true -Dgnome-shell=false -Dsystemd=true -Dgnome-shell=false -Dx-keybinder=false -Dcontrol-center-keybindings-dir=false -Dx-keybinder=true ..
