Master essential Tmux commands to create, manage, and navigate sessions. Use tmux new to start a session and tmux ls to list existing sessions. Detach with Ctrl+b d and reattach using tmux attach -t [session-number]. These commands form the foundation for efficient terminal multiplexing. Tmux sessions are created using the tmux new command. To start a named session, use tmux new -s [session-name]. This allows easy identification and management. Listing all sessions is done with tmux ls, which displays active sessions. Attach to a session using tmux attach -t [session-number] or tmux attach -t [session-name]. Detaching is achieved with Ctrl+b d, leaving the session running. Use tmux kill-session -t [session-name] to terminate a session. These commands provide full control over session lifecycle, enhancing workflow efficiency. Detaching from a session allows you to leave it running while returning to the shell. Use Ctrl+b d to detach without closing the session. To reattach, use tmux attach -t [session-number] or tmux attach -t [session-name]. Listing sessions with tmux ls helps identify the session to reattach to. Detaching preserves processes, enabling seamless resumption of work. This feature is ideal for managing long-running tasks or sharing sessions across devices. Create new windows with Ctrl+b c and switch between them using Ctrl+b n or Ctrl+b p. List windows with Ctrl+b w. Split panes vertically with Ctrl+b % and horizontally with Ctrl+b ‘”. Switch panes using arrow keys or Ctrl+b o. Merge panes with Ctrl+b ‘” and Ctrl+b ‘:. To create a new window in Tmux, press Ctrl+b c or use the command tmux new-window. Each window acts like an independent terminal tab, allowing you to run separate processes. Switch between windows using Ctrl+b n for the next window or Ctrl+b p for the previous one. List all windows with Ctrl+b w or tmux list-windows. You can also switch directly to a specific window by its number using Ctrl+b [window-number]. Rename a window with Ctrl+b , for better organization. Close a window by typing exit or pressing Ctrl+b &. Use tmux kill-window to close a specific window remotely. These commands enhance multitasking and workflow efficiency in Tmux. To split a pane vertically, press Ctrl+b %, and horizontally with Ctrl+b “. Switch between panes using Ctrl+b arrow-keys. Resize panes with Ctrl+b :resize-pane -U/D/L/R to adjust height or width. Use Ctrl+b x to close a pane or tmux kill-pane to close it remotely. These commands allow efficient multitasking and customization of your terminal workspace. Enter copy mode with Ctrl+b [, navigate with Ctrl+b [, copy with Ctrl+b Space, and paste with Ctrl+b ]. Buffers store copied text for quick access. To enter copy mode, press Ctrl+b [. Navigate using arrow keys or PgUp/PgDn for scrolling. Highlight text with movement keys and copy with Ctrl+b Space. Exit with Ctrl+c. This feature is essential for managing terminal outputs efficiently. To copy text in Tmux, enter copy mode with Ctrl+b [. Use arrow keys to navigate and Space to start selection. Press Enter to copy. Paste copied text with Ctrl+b ]. For buffering, use Ctrl+b : to access the command line and manage buffers. This feature simplifies text manipulation across sessions, enhancing productivity in terminal workflows. Customize Tmux to suit your workflow by altering key bindings and personalizing the status bar. Modify configurations to enhance efficiency and tailor your terminal experience. Customize Tmux key bindings to streamline your workflow. Modify the default prefix from Ctrl-b to Ctrl-a or another combination for easier access; Use the bind-key command in your tmux.conf file to redefine shortcuts. For instance, bind a key to quickly split panes or switch windows. This feature allows you to tailor Tmux to your preferences, enhancing productivity and efficiency in managing multiple terminal sessions. Refer to the cheat sheet for common key binding examples and best practices. Enhance your Tmux experience by personalizing the status bar. Use the status bar to display session information, memory usage, or system time. Modify its appearance and content in the tmux.conf file. Set the update interval with status-interval or toggle visibility with status. Customize colors and format using variables like status-bg and status-fg.Popular themes and scripts can further extend its functionality, making your workflow more efficient and visually appealing.
