Just learned a new tool that has somehow escaped me the last 15 years. prep is a simple tool that lets you grep through the names of running processes, returning just the PIDs. pkill takes that a step further, killing the matched processes1. The cool thing is that both support tab-completion under zsh.
Quick Examples
To find all running processes with the name jekyll
$ pgrep jekyll
70376Using the -l switch shows the process name as well
$ pgrep Finder
463
488
$ pgrep -l Finder
463 Finder
488 FinderSynExtNote how without the -l switch we don’t know that we’re matching
FinderSyncExt. Good thing we didn’t run pkill yet!
To match exactly, the -x switch is used. This can help solve the problem of
matching too greedily, especially when using pkill.
$ pgrep -x Finder
463Perhaps the too-greedy-by-default is why must instructions found on the web use killall over pkill. Still, I am liking the tab-completion offered by zsh.

A note of warning: pkill will kill processes that match only partially. So
pkill Finderwill killFinderandFinderSynExtprocesses. Be careful! ↩

Getting Started With Docker
Speak to anybody working in DevOps today, and Docker will be one of the hot topics of interest. At its core, Docker is a modular, layered approach to vitalization that runs on top of a host system’s kernel while keeping guest processes and filesystems separated.
Welcome to Jekyll Bootstrap
Welcome to Jekyll Bootstrap, a new from-scratch iteration at a Jekyll theme,
written using Bootstrap v4. By default, the first paragraph will appear
in the index summary, complete with styling. If you define an excerpt_separator in the post’s
frontmatter, you can have more or fewer paragraphs in the index excerpts. Try it!

On Simplicity
Over the past few years I’ve fallen into the habit of trying to start blogging regularly, only to fall into the same trap over and over. While I could rattle off the reasone, it really comes down to one thing: a lack of simplicity.
Jekyll Inline Conditionals With Liquid Filters
Often times when writing Jekyll templates, we need to do some conditional matching on certain blocks of text, returning one value in one instance, and a different value in another instance. Many times only a small portion needs to be changed, such as the name of a class, or inserting a default value when a variable is nil.
