If you need to execute many commands you can define another grouping here. Under each pane you then give the command to execute (e.g. ( even-vertical and even-horizontal are also options as defined in the tmux main page.) Next, we define the panes that get created inside each window using the layout. Within each window I set the layout to either main-horizontal, tiled, or main-vertical. You can rename these to whatever you’d like. (Adjusting the root can be useful if most of your commands start from the base of a project.) It then goes on to define three windows named status_things, io_things, and more_things. The script defines a name and an initial root directory. The structure is in a simple indented yaml format, so updating it is straightforward. This example script is quite silly, but you should be able to understand the general idea. If you want, you can also save and exit from the script and come back at a later time by running:Įdit your text file to have the following script:

You can now start to make changes to your new script. So if you’d rather open the file in a different editor or commit changes into a Git repository, you can. Running any combination of shell commands should work fine. The sample script is a very Ruby centric script, but don’t let that hold you back from using it for other things. If everything works, it should load your text editor ready to edit a new script named monitor. Also, since I’m running Zsh with Oh My Zsh I can just enable the tmuxinator plugin by adding it to my list of loaded plugins. The same alias should work if you’re using a different shell like bash. This allows me to run mux instead of the full command. Since that is way too much typing, I created an alias in my. Once complete, you should be able to run the tmuxinator command from the shell. It’s best to refer to the official instructions in the event things don’t go right.

Tmuxinator comes packaged as a Ruby Gem so installation should be as easy as: Let’s try it out! Setting up TmuxinatorĪssuming you have tmux already configured, setting up tmuxinator is pretty straightforward. The tool can create stored sessions by name and has a simple system for defining how things get positioned. Tmuxinator is a command line tool that helps to automate your tmux setup. Plus, I was still trying to be, uh, efficient. Tmuxinatorīuilding a script to talk to tmux might be fun, but it was going to take a complex configuration. You can also use C-m instead of Enter which appears to be a more standardized way of executing a command. The text Enter at the end informs tmux to send a carriage return and execute the text.

This command will execute inside your tmux session and cd to your home directory. For example, if you have a tmux session open you can issue something like: One ability of tmux is that it can receive command line requests and perform them on active sessions. The Internet has many tutorials on tmux if you’re interested. It’s a terminal multiplexer that is like Screen, but has some extra capabilities. If you haven’t used tmux before, you should definitely give it a try. Now I’m not afraid of a little setup for doing my work, but running nine services gets old and I’m lazy…eh…I mean efficient. This particular application required launching nine server instances before the website would work. Recently we inherited an existing codebase that uses a service oriented architecture.
