A quick trip through Zsh, Oh-my-zsh, and other power tools to make the command-line-based workflow smooth and&nbsp;cool.</p><p>The purpose of this post is to be my quick, copy-paste source of the commands that I use to set up my terminal on a new *nix system. However, if someone else finds it useful, that&rsquo;d be some cherries on&nbsp;top.</p> <p>This command prompt in the below image is the end&nbsp;goal.</p> <p><img alt="The end goal of this post" src="https://i.imgur.com/oZahIog.png"></p> <p>Assuming, I&rsquo;m on a standard pc/server with Ubuntu Linux and I have <span class="caps">CLI</span> access with <code>sudo</code>.

Also, whenever you want, you can invoke the config-wizard by executing <code>p10k configure</code> on the&nbsp;shell.</p> <p>Now is the time to enable the changes by restarting Zsh and enjoy the new config and the powerful&nbsp;prompt.</p> <div class="highlight"><pre><span></span><code><span class="linenos" data-linenos="1 "></span><span class="gp">$ </span><span class="nb">exec</span> zsh </code></pre></div> <h2 id="optional">Optional<a class="headerlink" href="#optional" title="Permanent link">&para;</a></h2> <p>Also, I usually install this very useful, but external plugin <code>zsh-syntax-highlighting</code> for&nbsp;oh-my-zsh.</p> <p><div class="highlight"><pre><span></span><code><span class="linenos" data-linenos="1 "></span><span class="gp">$ </span>git clone https://github.com/zsh-users/zsh-syntax-highlighting.git <span class="si">${</span><span class="nv">ZSH_CUSTOM</span><span class="k">:-</span><span class="p">~/.oh-my-zsh/custom</span><span class="si">}</span>/plugins/zsh-syntax-highlighting </code></pre></div> Don&rsquo;t forget to activate the plugin by including it in ~/.zshrc.
