# tmux tmux maintains its own copy buffer; when mouse support is turned on, highlighted text will be saved there rather than the system clipboard. However, it's relatively easy to access this data. ```bash # Output current save buffer to STDOUT. # tmux save-buffer - # Push tmux save buffer to system clipboard on Linux. # tmux save-buffer - | xclip -selection clipboard # Push tmux save buffer to system clipboard on macOS. # tmux save-buffer - | pbcopy ```
