The Red Hat Learning Subscription is such a great tool, I have learned so much this past year by having it.
Even though I have used a lot of the Red Hat products at work , going through the courses on the RHLS has made more proficient at using them.
For example, I've been using Ansible for a while now, and I am terrible about remembering all the options for each module. I would always go Google'ing for them. After spending a few days studying for the 407 exam I learned that you just have run ansible-doc <module-name> and it will give a "man page" of that module. I wish I knew when I first starting using Ansible. =)
So, what did you learn today?
Does it have to be from Red Hat courses?
I am preparing for RHCE on my own and today I learned how important it is to set the proper SELinux context on a multiuser Samba share.
Nope, any lessons learned apply.
SElinux can be a ticky to deal with. I like to use this command when hunting down SELinux denials
ausearch -m avc -ts recent | audit2allow
I learnt today that in order to preserve examples after exiting a man page, one can set the “PAGER” variable to ‘less -X’.
When you exit a man page, the content that was open remains on screen. I wish I knew this years ago.
That's a good one, super efficient use of the CLI. I'm always finding myself fighting the clock on exams because I'm not as effcient as I should be. Being able to navigate man pages is just as important as completing the task at hand.
