Enough to do what?

just to have a general knowledge of how things work. for example if you were in devops or security would you need to know more of linux?
To just feel comfortable yeah it's enough. You'd want a stronger understanding for any legitimate role though.

Could you expound on this more?
I can really only speak towards being a developer, but like if I asked you to tell me if an application is listening on a port, could you do it? Tell me what IP and address us resolving to? SSH into a server or transfer a file between two servers? Tell me what version of Python is installed and if its not 3, install it alongside Python 2? None of this stuff is all that complicated but it goes beyond the basics. When you get on the job you can Google to your heart's content, but if you get asked in an interview, stack overflow can't save you.

I see. You can easily find the commands on the internet to find these answers.
2 questions:
where did you learn linux?
How do you memorise the commands?
Tidbits in school, my first class she made us connect to the school network and submit our projects to her validator. One professor taught us how to spin up Ubuntu in VirtualBox, so I played with that for a while. Eventually I installed Linux on my laptop because it decided it didn't want to run Windows anymore. Partly on the job and through Google.
Repetition. See an error enough times, have to do the same action repeatedly, you learn what to do. Is my application running the right args? ps -ef and grep for the application name. Is it listening on the right port? netstat -a and grep for the port. Script not executing? ls -l and look at the permissions, chmod or chown as necessary. When it's daily life it becomes second nature.

breh. I was considering handwriting it all down and memorising all.That don't seem like the best idea, seems like I have to incorporate linux to my everyday life. Do you also know python?
Best way to ease in is VirtualBox and just use the VM in place of your main OS unless you NEED to. I know enough Python to get around but I'm not fluent in it. I made touch up to a script this morning written in Python I have a couple of Python scripts I've written for internal use, same with Bash.

Did you learn python the same way you learn't linux? Seeing as it's not an operating system how do you memorise the python language?
I picked up Python along the way. Our DBA needed an auditing script and I decided on Python because I thought I'd pick it up quicker than Bash. I already knew Java, so it wasn't a big jump to learn another language. Anything I didn't know, I just searched for. A big thing was opening a sub process, I Googled that. The more you use it, the more it sticks. In Bash I still have to look up how to do loops every now and then since most of my scripts are simple if/else logic. If you have other code to reference, that's also helpful.

after you picked up python bit by bit, where did start learning to create python scripts? There's a difference between learning functions, loops, tuples, maths on python and actually create a script from the beginning. it seems that's where most falter.
I learned as I scripted. First step was opening a file, next was scraping a directory for all files of a certain type, then parsing the file for what I need, then running some queries against a database. When there is a task to complete it's easier than just learning in isolation. For example, I'm trying to learn Japanese right now but I don't have a way to put the skills to proper use, so I'm finding difficulty learning and retaining it. The only method I have currently is repetition.
Just passed the CySa+ with a 750 (the lowest passing score you can get is a 750) By the half way point I was 100 percent sure I failed.
I could've done way better but I'm just burnt out on reading through the book and I start school on Friday and didn't want to keep having this hovering over my head. I completed Jason Dion's course weeks ago.
Did it online at home which was interesting, I was super nervous because I had a sleeping 4 month old who could wake up crying at any minute (your exam would end if you leave the desk) and my fukking dog kept barking outside. I don't feel as proud of this one as my other certs that I worked super hard on, but I definitely know I will need to keep learning the material.
