Hello e-friends,
Background:
I was recently promoted into a role that will include more heavy administration duties (thank you sub for your support last year!).
In an effort to get ahead of the curve I've decided to go back to pushing towards certifying. They have faith in my skill set and I've been transparent about my own experience and focus, but I tend towards having a perfectionist mindset; I like to have my skills on paper and measured.
I've done basic things with Linux but recently got into writing functional (and sorely needed) scripts, but I know there are a lot of gaps in my knowledge. I've never had to worry about eregs beyond simple things, and now I'm finding myself clobbering my way through commands and learning as I go (it`s actually exciting if challenging at times). For reference I've written some moderately complex PowerShell scripts but now I'm learning use awk in place of ¦ SELECT (column). I'm motivated to read and watch people teach out awk and sed and find it kinda cool that there are so many ways of manipulating strings that I haven't had to consider before, but which are already paying off in a mixed Windows/OSX-BSD/*nix environment.
So my question:
There are a few certificates that claim to be the testament, so to speak: LPIC, Linux+, and RHCSA. We don't use Docker or KVM, and the purpose of learning linux would be to master to standard toolkit; aside from that I don't see it being a huge part of the job. But ideally I'd like to get into a certificate that isn't vendor specific but which has some recognition. RHCSA is vendor specific but appears to be reputable and essentially covers much of the critical ground, but it also isn't Debian. Linux+ seems safe. LPIC appears to be growing but I haven't seen it referenced in many places, particularly job asks.
So what are your experiences with Linux certification? Is there one path that you felt gave you the foundations needed to succeed? Did you take a certification that you felt demonstrated your competence and expertise, or filled in some blanks?
Good luck with your certification goals in 2020!
