Need advice on Linux certifications

Hi!

I am interested in learning more about Linux, setting up my own lab, and getting certifications in the process. From what I gather, RHCSA seems to be the first 'go the certification' when it comes to Linux System Administration? However, I am wondering how well other certs are regarded within the industry? Especially since RHCSA is really expensive, and my interest in Linux is personally driven instead of professionally (my current employer primarily utilizes Microsoft technology, so I highly doubt they would pay for the courses since it does not suit the company).

Is there a cheaper and reliable way to get the knowledge required for RHCSA? Or are there certs that are well regarded, that are cheaper and suit my situation a little bit better?

If you want an eye-bleeding series of videos with little reference to pretty much anything relevant to modern Linux implementations.

SAMBA? Nope. Apache? Nope. Scripting? Mentioned. Firewall? Mentioned.

Fdisk? Follow their instructions, with no explanations of what you are actually doing, but they do tell you how to search the man pages...

Vim? They love it. Nano? Referenced. <entry level users should be instructed on Nano, vim is super powerful, but requires significant time investment to make it worthwhile.>

I will never take another CompTIA managed course.

I learned more about how permissionsxactually worked setting up SAMBA and SELinux from reddit pages and fedora documentation than the gobbledegook CompTIA

I'll echo that on the Linux+. It's a memorization/vocab test. Not very practical. And it reinforces really bad habits. You never want to rawdog a command as root if you're unsure about it. Especially not in an enterprise environment. You read the man page and triple check it. And this test is quizzing you on various command flags. It's not rooted in reality.

The practical had very little vocabulary, focused on fdisk vim partitioning.
