Abhi from Linux Handbook: LHB Linux Digest #25.24: Learning Corners, apropos, Proxmox Monitoring, Handling Huge Log with Docker

Hey there,

Have you checked the "learning corner" on the redesigned Linux Handbook website? It's a page from where you can access collections of tutorials on a specific topic, like Nano or Vim.

Learning Corner

Start learning in a more organized and streamlined manner

Linux Handbook •Abhishek Prakash

This is different from our courses, as those are more hands-on in approach and they teach you things in a sequence. The collections in Learning Corner are different as they are more of an assortment of tutorials on a specific topic organized in a sequence but not as cohesive as a course. I will be adding more collections in the Learning Corner in coming days.

By the way, ~~I use Arch~~ what do you think of the term "learning corner"? If you have a better suggestion, please let me know. If I like your suggestion and use it, you will get 1 year of Pro subscription for free (if you don't have it already) 😄

Man pages are good but some times you want something quicker. That's where apropos command comes in handy.

💡Quick terminal tip

If you are searching for a specific set of patterns using grep command repeatedly, better use a pattern file, than providing it as inline options.

$ grep -f patterncheck.txt agatha.txt
The Sittaford Mystery
Peril at End House
Lord Edgware Dies

Where, for example, patterncheck.txt will be:

Mystery
Lord
House
