<p>Terminology:</p>
<ul>
<li><code>session</code> is a collection of pseudo terminals which can have multiple
<code>windows</code></li>
<li><code>window</code> uses the entire screen and can be split into rectangular <code>panes</code></li>
<li><code>pane</code> is a single pseudo terminal instance</li>
</ul>
<h1><a class="header" href="#tmux-cli" id="tmux-cli">Tmux cli</a></h1>
<pre><code class="language-markdown"># Session
tmux                        creates new session
tmux ls                     list running sessions
tmux kill-session -t &lt;s&gt;    kill running session &lt;s&gt;
tmux attach -t &lt;s&gt; [-d]     attach to session &lt;s&gt;, detach other clients [-d]
tmux detach -s &lt;s&gt;          detach all clients from session &lt;s&gt;

# Environment
tmux showenv -g             show global tmux environment variables
tmux setenv -g &lt;var&gt; &lt;val&gt;  set variable in global tmux env

# Misc
tmux source-file &lt;file&gt;     source config &lt;file&gt;
tmux lscm                   list available tmux commnds
tmux show -g                show global tmux options
tmux display &lt;msg&gt;          display message in tmux status line
</code></pre>
<h2><a class="header" href="#scripting" id="scripting">Scripting</a></h2>
<pre><code class="language-markdown"># Session
tmux list-sessions -F '#S'           list running sessions, only IDs

# Window
tmux list-windows -F '#I' -t &lt;s&gt;     list window IDs for session &lt;s&gt;
tmux selectw -t &lt;s&gt;:&lt;w&gt;              select window &lt;w&gt; in session &lt;s&gt;

# Pane
tmux list-panes -F '#P' -t &lt;s&gt;:&lt;w&gt;   list pane IDs for window &lt;w&gt; in session &lt;s&gt;
tmux selectp -t &lt;s&gt;:&lt;w&gt;.&lt;p&gt;          select pane &lt;p&gt; in window &lt;w&gt; in session &lt;s&gt;

# Run commands
tmux send -t &lt;s&gt;:&lt;w&gt;.&lt;p&gt; &quot;ls&quot; C-m    send cmds/keys to pane
tmux run -t &lt;p&gt; &lt;sh-cmd&gt;             run shell command &lt;sh-cmd&gt; in background and report output on pane -t &lt;p&gt;
</code></pre>
<p>For example cycle through all panes in all windows in all sessions:</p>
<pre><code class="language-bash"># bash
for s in $(tmux list-sessions -F '#S'); do
    for w in $(tmux list-windows -F '#I' -t $s); do
        for p in $(tmux list-panes -F '#P' -t $s:$w); do
            echo $s:$w.$p
        done
    done
done
