In the previous lesson, we explored regular expressions to create a Bash one-liner to extract words from Thunderbird email subject lines.
While it worked well for a simple task, residue was not filtered, and this required manual editing.
Can we improve it further to handle inconsistencies and reduce the manual edits? Yes! This article demonstrates using sed and regular expressions to eliminate any manual editing.

Do you use the Thunderbird email client for your emails? Do you want to grab words from a large list of subject lines?
There are times when we might want to get a single word from each subject line in a collection of emails. Sure, we could look and type by hand into a text file, but that is too tedious. Let’s use a computer to perform the task using Bash!
This article describes how to create a Bash one-liner that will grab a word from each subject line of each Thunderbird email and store the sorted result into a text file.

What? You say a 3.5″ 7200 RPM hard drive generating heat from its loud whirring noise is not fast enough? Then, why not upgrade to faster, smaller storage in the form of NVMe in an M.2 slot?
In my attempt to develop a faster system, I tried the 500GB and the 1TB Samsung 970 EVO Plus NVMe M.2 stick in Linux Mint 19.1 to replace a slow, outdated, out-of-warranty 7200 RPM hard drive from 2008.
Here are my results and thoughts about this fantastic stick of silicon the size of a stick of gum used with Linux Mint.

It blinks! I pulsates! It offers high precision! It’s back!
The Mad Catz R.A.T.7 and the M.M.O.7 are without a doubt the best computer mice that I have ever used, and they continue to work to this day.
However, after a few years of constant use, buttons are becoming loose, and plastic is becoming sticky. What better excuse to acquire a new mouse?
Mad Catz is back with an improved RAT line of eight different models. With the Mad Catz RAT 8+ being closest to the original R.A.T.7 that I adore so much, I decided to purchase the 8+ for myself and see how well it performs with today’s Linux Mint 19.1.
Wow! Am I glad I did!

“A microSD card is a microSD card, right?”
With so many microSD cards available, what features could one card offer that are superior to another? That depends upon the application.
Needing a microSD card upgrade for write-intensive purposes, I tried the Samsung PRO Endurance 64GB and 128GB microSD cards that are designed especially for continuous writing and supposedly offer better protection against the elements.
These are newer cards, so do they work with Linux?

Need more space for backups using an external USB drive? The Seagate Expansion offers 4TB of unformatted room to grow, and it is compatible with Linux!
Parkinson’s Law of Data states that data expands to fill the available space. A 10MB hard drive was deemed a phenomenal amount of storage space in the early 1980’s with the IBM PC XT.
“Who would possibly fill up 10MB?”
But people managed to fill up that space, and then beg for more. Now, we measure hard drive storage space in gigabytes and terabytes as the demand for more storage space increases.
With all of this data, it is important to back it up, and this is best accomplished on an external medium, such as cloud storage or an external hard drive.
The Seagate Expansion 4TB Portable Hard Drive is an external USB 3.0 drive that offers plenty of room to grow in a fairly small package.
How well does it perform with Linux Mint 19.1? Let’s see…
