  • Cat a File Without Comments

    Share on: twitter facebook linkedin copy

    It's super handy when a Linux config file is loaded with comments to tell you precisely how to configure the thing, but all those comments can really get in the way when you're trying to review the current configuration. Next time, instead of scrolling through page after page of lengthy embedded explanations, just use: …

    K8s on vSphere: Building a Kubernetes Node Template With Packer

    I've been leveraging the open-source Tanzu Community Edition Kubernetes distribution for a little while now, both in my home lab and at work, so I was disappointed to learn that VMware was abandoning the project. TCE had been a pretty good fit for my needs, and now I needed to search for a replacement. VMware is …

    Enable Tanzu CLI Auto-Completion in bash and zsh

    Lately I've been spending some time getting more familiar with VMware's Tanzu Community Edition Kubernetes distribution, but I'm still not quite familiar enough with the tanzu command line. If only there were a better way for me to discover the available commands for a given context and help me type them correctly... …

    Script to Convert Posts to Hugo Page Bundles

    In case you missed the news, I recently migrated this blog from a site built with Jekyll to one built with Hugo. One of Hugo's cool features is the concept of Page Bundles, which bundle a page's resources together in one place instead of scattering them all over the place. Let me illustrate this real quick-like. …

    I'm preparing to migrate this blog thingy from Hashnode (which has been great!) to a GitHub Pages site with Jekyll so that I can write posts locally and then just do a git push to publish them - and get some more practice using git in the process. Of course, I've written some admittedly-great content here and I don't …

    Automatic unattended expansion of Linux root LVM volume to fill disk

    While working on my vRealize Automation 8 project, I wanted to let users specify how large a VM's system drive should be and have vRA apply that without any further user intervention. For instance, if the template has a 60GB C: drive and the user specifies that they want it to be 80GB, vRA will embiggen the new VM's …

    Setting up Linux on a new Lenovo Chromebook Duet (bonus arm64 complications!)

    I've written in the past about the Linux setup I've been using on my Pixel Slate. My Slate's keyboard stopped working over the weekend, though, and there don't seem to be any replacements (either Google or Brydge) to be found. And then I saw that Walmart had the 64GB Lenovo Chromebook Duet temporarily marked down to a …

  • Finding the most popular IPs in a log file

    Share on: twitter facebook linkedin copy

    I found myself with a sudden need for parsing a Linux server's logs to figure out which host(s) had been slamming it with an unexpected burst of traffic. Sure, there are proper log analysis tools out there which would undoubtedly make short work of this but none of those were installed on this hardened system. So this …
