Zsh copy & paste system wide for Linux (X11& Wayland with customizable paste and copy commands)

system-wide-clipboard-linux.zsh

# Forked from https://gist.github.com/varenc/e4a22145c484771f254fa20982e2cd7f

## 2024-03-30: Ported it to Linux, added display detection and customizable copy/paste commands
##             Using environment variables
## 2020-05-16: Changed `echo` to `printf` so that backslashes are not interpretted by echo
##             and so that CUTBUFFER shows up exactly in the pasteboard without modification

# Detect display server
display_server=$(echo $DISPLAY | cut -d: -f1)

# Default commands
: ${ZSHCLIP_COPY_COMMAND:="xclip -sel clip"}
: ${ZSHCLIP_YANK_COMMAND:="xclip -o -sel clip"}

# If running on Wayland, use wl-clipboard
if [ "$display_server" = "wayland" ]; then
    ZSHCLIP_COPY_COMMAND="wl-copy"
    ZSHCLIP_YANK_COMMAND="wl-paste"
