ADMINISTERIA

Learning Linux skills has a problem: there are just so many tools and technologies to choose from. Stuart Burns is your guide to success.

The great thing about Linux is that it is inexpensive and you can get the skills from books such as those by Sander Van Vugt. These books cover what would be in the Linux administrator exam. RHEL certification is still the hot ticket.

Oracle offers a certification that is very similar to RHEL and covers Oracle Enterprise Linux. RHEL and OEL are extremely similar. The interesting thing is that the OEL exam is less than half the price of the RHEL one.

Unfortunately, very few Debian exams exist. There is the LPIC series of certifications but we have not known one person who held the LPIC certification. We would recommend this direction only if there is some explicit reason that RHEL certification isn’t enough.

As companies prioritise automation, containerisation and scalable cloud-native infrastructure, Linux DevOps roles are central to modern IT operations. It’s critical to build a focused skill set that marries with real-world tools and workflows. The trick is identifying those useful skills from the hype.

Bash Scripting

Shell scripting is key to automation in any Linux-based role. Being able to write simple but effective scripts to automate tasks saves time and reduces errors in repetitive operations. Pretty much every DevOps role need competency in writing and debugging Bash scripts.
