pbcopy from linux shell

Working across Mac, Windows, and Linux via SSH? Ever wished you could pbcopy from within a remote SSH session? Add this "one-liner" to your ~/.bashrc or ~/.profile:

pbcopy() {
 printf "\033]52;c;%s\033\\" "$(cat | base64 -w0)"
}

If you use tmux you will need a bit more:

pbcopy() {
  if [ -n "$TMUX" ] && command -v tmux >/dev/null 2>&1; then
    # Read stdin into tmux buffer and also copy to system clipboard via OSC 52
    tmux load-buffer -w -
  else
    # Direct OSC 52 for non-tmux shells
    # Portable base64: avoid line wraps
    printf '\033]52;c;%s\007' "$(base64 | tr -d '\n')"
  fi
}
