Listing and Switching Between Sessions
To list all active tmux sessions, use the command tmux ls․ This displays a list of sessions with their names and attached clients․ To switch between sessions, press the keybinding prefix + s (default is Ctrl+b s), which opens a menu to select the desired session․ This feature allows efficient navigation and management of multiple sessions, enhancing workflow and productivity for users working with multiple tasks simultaneously․
Renaming Sessions
To rename a tmux session, use the command tmux rename-session -t new_name․ This updates the session’s name for easy identification․ Additionally, press prefix + $ (default is Ctrl+b $) to rename the current session interactively․ This feature helps organize and manage multiple sessions efficiently, making it easier to distinguish between different tasks or projects․
Killing Sessions
To terminate a tmux session, use the command tmux kill-session -t target_session․ Replace “target_session” with the name or number of the session you wish to terminate․ This command will close all windows and panes within the specified session․ Alternatively, you can use the shortcut prefix + d (default is Ctrl+b d) to detach and kill the current session․ This feature is useful for cleaning up unused or completed tasks efficiently․
Window Management
Tmux allows efficient management of multiple terminal windows within a single session․ Users can create, navigate, and rename windows using keyboard shortcuts, enhancing productivity․
Creating New Windows
In tmux, new windows can be created within a session using keyboard shortcuts or commands․ Pressing Ctrl-b c opens a new window, while tmux new-window achieves the same via command line․ This feature allows users to manage multiple tasks simultaneously, improving workflow efficiency․ New windows can be easily navigated using Ctrl-b n for next or Ctrl-b p for previous, streamlining multitasking within a single session․
Navigating Between Windows
Navigating between windows in tmux is seamless with keyboard shortcuts․ Use Ctrl-b n to switch to the next window and Ctrl-b p for the previous one․ You can also use Ctrl-b l to move to the last visited window․ Additionally, the tmux select-window command allows switching windows by number, enhancing navigation flexibility and enabling efficient multitasking within sessions․
Renaming Windows
Renaming windows in tmux helps organize your workflow․ Use the keyboard shortcut Ctrl-b , (comma) to rename the current window․ Alternatively, you can use the command tmux select-window -t
Closing Windows
To close a window in tmux, use the keyboard shortcut Ctrl-b c․ This command terminates the current window and all its panes․ Alternatively, you can use the command tmux kill-window to close the current window․ If you want to close a specific window, use tmux kill-window -t
Panes Management
Panes allow splitting a tmux window into multiple views․ Use Ctrl-b % to split vertically and Ctrl-b ” for horizontal splits․ Navigate panes with arrow keys or Ctrl-b followed by direction keys․ This feature enhances multitasking efficiency․
Splitting Panes Vertically and Horizontally
In tmux, you can split panes vertically using Ctrl-b % and horizontally using Ctrl-b “․ Vertical splits are ideal for side-by-side comparisons, while horizontal splits help manage multiple tasks․ Use arrow keys or Ctrl-b followed by direction keys to navigate between panes․ This feature allows efficient multitasking and organized workspace management within a single session․
Navigating Between Panes
Navigate between panes using Ctrl-b followed by arrow keys (up, down, left, right)․ This allows seamless switching between split panes․ Press Ctrl-b and the corresponding direction key to move focus․ You can also use Ctrl-b 1, 2, etc․, to directly switch to pane numbers․ This feature enhances multitasking by enabling quick access to different terminal instances within a single window․
Resizing Panes
Resize panes using keyboard shortcuts for efficient layout adjustments․ Press Ctrl-b followed by : to enter command mode, then type resize-pane with directional arrows (e․g․, Up, Down, Left, Right) to adjust size․ Alternatively, use Ctrl-b Z to toggle pane zoom․ These commands allow precise control over pane dimensions, optimizing your workspace for better multitasking and visibility․ Resize panes effortlessly to suit your workflow needs․
Closing Panes
To close a pane in tmux, use the keyboard shortcut Ctrl-b x or type Ctrl-d to exit the current pane․ You can also use the command tmux kill-pane to close the active pane․ To close all other panes except the current one, press Ctrl-b : and enter kill-pane -a․ For additional control, use kill-pane -o to close all panes except the last one․ These commands help manage your workspace efficiently by allowing quick pane closures․
