12/6/2023 0 Comments Tmux rename window![]() For that, you need tmux, a single terminal that puts you in control of multiple command prompts. But sometimes you need to run commands manually. Ansible, for instance, ensures all systems are in the same state, and sometimes a simple cron job will do. ![]() There are many ways to automate tasks across systems. ![]() The default command is z to zoom and the same command un-zoom.Whether you're starting up an elaborate Raspberry Pi homelab or you're managing a building full of workstations, sometimes you need to do the same task on multiple hosts. long lines are wrapping), you can get a full screen view of a single pane without closing the others. Zooming in on a single paneĮvery time you split into a new pane, screen real estate is divided. Newly created panes while synchronize-panes is enabled are also active. To disable, do the same but with off instead of on. To enable via the statusbar run :synchronize-panes on or within a tmux shell tmux set-window-option synchronize-panes on. This can be helpful for a variety of cases such as comparing files, editing multiple files, running the same command on multiple hosts, and other one-off tasks that may take longer to script. If you have split into two or more panes, you can have your put key commands go to both panes.įor example if you have 3 panes, one in /path1/, one in /path2/, and one in /path3/, and you synchronize panes and run touch test, that will run in every pane, resulting in a /path1/touch, /path2/touch, and /path3/touch. Inside a shell that is tmux rename-session. Similarly to window renaming, the default session rename shortcut is $. As with other shell commands, quote the new name if there’s spaces. ![]() If you’re at shell inside tmux already, you could instead run the command tmux rename-window. The default shortcut to rename the current window is, then you will be prompted inside the statusbar. You can rename the windows to something more meaningful, such as “code”, “testing”, “metrics”, “notes”, etc. If you use multiple sessions and windows, they eventually become more difficult to keep track of.īy default, your tmux statusbar will display something like 0:windowname 1:windowname 2:windowname 3:windowname which may look like 0:bash 1:bash 2:vim 3:bash. Note: there are non-empty default values for status-left and status-right that the above configuration would overwrite. If you already customize your status line, be aware you can include the output of arbitrary shell commands.įor example, in your tmux config, this will print your IP address: set-option -g status-right '#(curl )' Put the tmux host’s ip address in the statusline Only set it as large as you think you’ll actually need, as tmux’s RAM usage will be increased per window, even if not utilized (lines are pre-allocated). In your tmux config, add this: set-option -g history-limit 10000 The number of lines saved in your tmux pane defaults to 2000. If there’s an error, tmux will print something like ~/.nf:18: unknown command: sset in the active pane and not apply.Īlternately, if you prefer to just type a shell command, you can run (inside your tmux session) tmux source-file ~/.nf. Then you can r and the config will be reloaded. If you are experimenting with changes in your tmux config file, you may prefer to not restart your tmux instance every time you make a change. However, if you cd /long/path/to/working/area/ and open a new tmux window or pane, you may prefer to start off in /long/path/to/working/area/.Īdding this to your tmux config file will change the behavior so every new window will be in the originating window’s path. If you are in $HOME and run tmux, every new window and pane will start in $HOME. New windows and panes start in the same path Note: the examples assume the default tmux config at ~/.nf. There’s lots of resources on tmux configuration and commands.
