This is like a re-post of a question from askubuntu.com. To get to that post, I usually had to google it. So, I’ll post it here so I know where to look for when I need it again.

Early last year I started a blog post about the preparation for Red Hat Certified System Administrator (RHCSA) exam. My intention back then was to have more posts follow suit about the exam topics. Like many things in life, things don’t always go according to plan. That was the only post, but I passed the RHCSA exam. Today, I’m going to start another new post about the preparation for the Red Hat Certified System Engineer (RHCSE) exam. I already booked an exam which is taking place on September 12. The exam is 3.5 hours long and cover a broader range than before. ...

If your search engine take you to this page, chances are you get used to use chsh to change user’s shell. On Fedora (28 at least), chsh is not available by default. You can install util-linux-user according to this post to get the chsh command. However, there is another alternative which I didn’t even think of - use usermod command.

Tonight, I tried to setup this extension on a brand new laptop running Fedora 28. For some reason, it doesn’t work at all. Luckily, I found another perl extension which works quite well. Here’s how I got it working on this Fedora 28, with Sway tiling windows manager (instead of i3 because I run Wayland with this Fedora 28). ...
