What did you learn today?

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.

Re: What did you learn today?

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

Good luck!

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.

Re: What did you learn today?

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.

@jthiatt 

Somebody told me that you need to have a typing speed of 50 WPM or more to comfortably sit Red Hat exams.

:-(  :-( [shivering with fear as exam hour approaches] but that's one word per  just a bit more than a second!

That's not going to help you when you take exams which has products administered by WebUI ;-)

Re: What did you learn today?

Isn't WebUI just a wrapper for the CLI anyway?
