Welcome to the first newsletter in 2023!

For me the “Zeit zwischen den Jahren” (“time between the years”, referring to the days between Christmas and New Year’s day plus in general some days around) was quite relaxed, and besides a one-week offline trip to Slovenia with my wife, these days were mostly working days, preparing new content, creating videos, and planning for 2023.

Since Thursday, there is the online jChampions Conference going on, a free conference with sessions by Java Champions only, for which yours truly will also give a session (Tuesday 4 pm CET) on the topic of productivity: Principles of Effective Developers. I think this is going to be a fun one, 45 minutes full of productivity tips, so join us!

This newsletter episode will also be full of productivity-focused content on command line tips and other things.

Command Line Scripts and Automation in My Setup

I’ve published a video on in which I’ve put together some command line scripts and automation helpers from my setup that are part of my everyday work. I find these type of examples helpful to watch to get some inspiration for one’s own setup, so I compiled a list for myself:

Helpful Command Line Scripts and Automation in My Setup

To give you a sneak peek, here’s one that I use to calculate time zones quickly on the command line, without opening a website:

$> timezones 18:00 # shows what my 18:00 will be in other time zones
Los Ang.: Sun, 22 Jan 09:00
Central:  Mon, 23 Jan 11:00
New York: Mon, 23 Jan 12:00
UTC:      Mon, 23 Jan 17:00
London:   Mon, 23 Jan 17:00
Berlin:   Mon, 23 Jan 18:00
Moscow:   Mon, 23 Jan 20:00
Bangkok:  Tue, 24 Jan 00:00
Tokyo:    Tue, 24 Jan 02:00

Of course, the mentioned scripts can be found on GitHub, on my dotfiles repository.

Helpful Command Line Scripts and Automation in My Setup


My Most Used CLI Commands

Similarly to the previous topic, I’ve also compiled a list of commands that I keep using all the time. I find it quite interesting to have a look at one’s shell history file once in a while, and see whether there is an easier way around, such as defining aliases or using shortcuts.

My Most Used CLI Commands

This list contains mostly Unix commands and other shell features such as piping or globbing, and I think can help even if one just seldomly uses the command line.


Quickly Extracting Html Content With xmllint

On the command line, xmllint is a helpful tool to format and extract XML, but it can also work with HTML markup. In order to extract the content of individual tags, you can use XPath expressions:

xmllint --xpath 'string(//h1)' --html index.html 2&> /dev/null

This extracts the text content of the first <h1> tag and supresses any warnings on invalid HTML.

I use this for example to quickly extract the titles of my blog posts:

curl --silent '' \
  | xmllint --xpath 'string(//h2)' --html - 2&> /dev/null

Yet another helpful tool to have in one’s command line belt.
