X Clipboard – How to Operate X Clipboard from Command Line

I ended up with a partial solution to the problem by installing xbindkeys and setting up the following .xbindkeysrc in my home dir:

"xclip -selection primary -o | xclip -selection clipboard -i"
mod4+c

"sh -c 'xclip -selection clipboard -o | xvkbd -xsendevent -file - 2>/dev/null'"
mod4+v

These shortcuts allow me to copy text into the X11 clipboard from a terminal emulator like urxvt, as well as paste from the X11 clipboard into the terminal emulator. Qt applications work for copying+pasting as well.

However, when using Gtk applications (like Firefox, gedit, etc.) if I tap the Mod4+V to paste, it doesn't seem to work. If I hold the keys down for a few seconds and then release, it pastes fine. Bizarre.

Yes, basically, you'd need to offer the CLIPBOARD selection either as

• text/uri-list with the content being

  /path/to/file1
  /path/to/file2
  

• application/x-kde-cutselection or x-special/gnome-copied-files with content copy\nfile://$path1\nfile://$path2\0 or cut\nfile://$path1\nfile://$path2...\0

With xclip you can achieve this with something like

find "$PWD" -name "*.pdf"| xclip -i -selection clipboard -t text/uri-list

I've also found this loliclip command that looked promising, but though I could retrieve the values, I wasn't able to store them and have them retrieved from loliclip by pcmanfm successfully.

You also should be able to implement it in a few lines of perl-tk.
