-<span>Before continuing to read this post, I encourage you to get familiar with Tmux first (unless you already know the basics). You can go through the official getting started guide:</span><br />
-<br />
-<a class='textlink' href='https://github.com/tmux/tmux/wiki/Getting-Started'>https://github.com/tmux/tmux/wiki/Getting-Started</a><br />
-<br />
-<span>I can also recommend this book (this is the book I got started with with Tmux):</span><br />
-<br />
-<a class='textlink' href='https://pragprog.com/titles/bhtmux2/tmux-2/'>https://pragprog.com/titles/bhtmux2/tmux-2/</a><br />
-<br />
-<span>Over the years, I have built a couple of shell helper functions to optimize my workflows.  Tmux is extensively integrated into my daily workflows (personal and work). I had colleagues asking me about my Tmux config and helper scripts for Tmux several times. It would be neat to blog about it so that everyone interested in it can make a copy of my configuration and scripts.</span><br />
-<br />
-<span>The configuration and scripts in this blog post are only the non-work-specific parts. There are more helper scripts, which I only use for work (and aren&#39;t really useful outside of work due to the way servers and clusters are structured there).</span><br />
-<br />
-<span>Tmux is highly configurable, and I think I am only scratching the surface of what is possible with it. Nevertheless, it may still be useful for you. I also love that Tmux is part of the OpenBSD base system!</span><br />

-<span>There is a lot going on here. Let&#39;s have a detailed look at what it is doing. As a note, the function relies on GNU Date, so MacOS is looking for the <span class='inlinecode'>gdate</span> commands to be available. Otherwise, it will fall back to <span class='inlinecode'>date</span>. You need to install GNU Date for Mac, as it isn&#39;t installed by default there. As I use Fedora Linux on my personal Laptop and a MacBook for work, I have to make it work for both.</span><br />
-<br />
-<span>First, a Tmux session name can be passed to the function as a first argument. That session name is only optional. Without it, Tmux will select a session named <span class='inlinecode'>T$($date +%s)</span> as a default. Which is T followed by the UNIX epoch, e.g. <span class='inlinecode'>T1717133796</span>.</span><br />

-<br />
-<span>Note also the call to <span class='inlinecode'>tmux::cleanup_default</span>; it would clean up all already opened default sessions if they aren&#39;t attached. Those sessions were only temporary, and I had too many flying around after a while. So, I decided to auto-delete the sessions if they weren&#39;t attached. If I want to keep sessions around, I will rename them with the Tmux command <span class='inlinecode'>prefix-key $</span>. This is the cleanup function:</span><br />

-<span>The cleanup function kills all open Tmux sessions that haven&#39;t been renamed properly yet—but only if they aren&#39;t attached (e.g., don&#39;t run in the foreground in any terminal). Cleaning them up automatically keeps my Tmux sessions as neat and tidy as possible. </span><br />

-<span>This SSHs into the remote server specified and then, remotely on the server itself, starts a nested Tmux session. So we have one Tmux session on the local computer and, inside of it, an SSH connection to a remote server with a Tmux session running again. The benefit of this is that, in case my network connection breaks down, the next time I connect, I can continue my work on the remote server exactly where I left off. The session name is the name of the server being SSHed into. If a session like this already exists, it simply attaches to it.</span><br />

-<br />
-<span>To make nested Tmux sessions work smoothly, one must change the Tmux prefix key locally or remotely. By default, the Tmux prefix key is <span class='inlinecode'>Ctrl-b</span>, so <span class='inlinecode'>Ctrl-b $</span>, for example, renames the current session. To change the prefix key from the standard <span class='inlinecode'>Ctrl-b</span> to, for example, <span class='inlinecode'>Ctrl-g</span>, you must add this to the <span class='inlinecode'>tmux.conf</span>:</span><br />
-<br />
-<pre>
-set-option -g prefix C-g
-</pre>
-<br />
-<span>This way, when I want to rename the remote Tmux session, I have to use <span class='inlinecode'>Ctrl-g $</span>, and when I want to rename the local Tmux session, I still have to use <span class='inlinecode'>Ctrl-b $</span>. In my case, I have this deployed to all remote servers through a configuration management system (out of scope for this blog post).</span><br />
-<br />
-<span>There might also be another way around this (without reconfiguring the prefix key), but that is cumbersome to use, as far as I remember. </span><br />

After a busy workday, I often end up with around twenty sessions on my laptop. This is where fuzzy searching for session names comes in handy, as I often don&#39;t remember the exact session names.</span><br />

-<span>However, since I started using Tmux, I retired ClusterSSH, as it came with the benefit that Tmux only needs to be run in the terminal, whereas ClusterSSH spawned terminal windows, which aren&#39;t easily portable (e.g., from a Linux desktop to macOS). The <span class='inlinecode'>tmux::cluster_ssh</span> function can have N arguments, where:</span><br />
-<br />
-<ul>
-<li>...the first argument will be the session name (see <span class='inlinecode'>tmux::tssh_from_argument</span> helper function), and all remaining arguments will be server hostnames/FQDNs to connect to simultaneously.</li>
-<li>...or, the first argument is a file name, and the file contains a list of hostnames/FQDNs  (see <span class='inlinecode'>tmux::ssh_from_file</span> helper function)</li>

-<span>It expects at least two arguments. The first argument is the session name to create for the clustered SSH session. All other arguments are server hostnames or FQDNs to which to connect. The first one is used to make the initial session. All remaining ones are added to that session with <span class='inlinecode'>tmux split-window -t $session...</span>. At the end, we enable synchronized panes by default, so whenever you type, the commands will be sent to every SSH connection, thus allowing the neat ClusterSSH feature to run commands on multiple servers simultaneously. Once done, we attach (or switch, if already in Tmux) to it.</span><br />
