xpaste - paste text into X windows that don't work with selections
xpaste <<EOF This text will be pasted into a window of your choosing. EOF
Some applications refuse to work with any of the three selection buffers that X/X11/Xorg has: the middle-mouse selection, secondary selection and the CTRL-(SHIFT-)V clipboard selection.
If you have to insert long or difficult to type text (generated passwords), not being able to paste can be troublesome.
xpaste will read the text to paste from standard input, keep it in memory and wait for you to press ENTER. When you do, it pastes the held text into the newly focused window.
See this before/after example where the username is pasted into the SuperMicro ipmiview Java application that doesn't accept "paste" input through the middle-mouse or CTRL-V:
The pasting of text happens through "faked" keypress events. And as you can see from the example, it works.
NOTE: xpaste does not work on Wayland because it disallows
applications to meddle with other applications. However, you
can start both applications under the Xwayland compatibility
