A dictionary? I mean, that's neat and all, but not all that useful is it? I might check the weather once a day, tops. This is better solved by having a widget on my smartphone. Same for the dictionary, and same for short google searches too (Firefox Focus).
I had a twinge of hope that this might have been more of an introduction to using the terminal effectively on Linux for diagnoses.
I'm new to Linux, and every time I have an issue and find a thread addressing it, they ask for me to run a whole bunch of commands and paste a bunch of logs. I'm happy to do that, don't get me wrong, but I rarely have the faintest idea of what it is that I'm typing in.
Usually when the internet says "Run these commands", they either don't tell you what they do, or tell you to just check `man`. The problem is that man pages can be super long, can have a somewhat intimidating syntax, and 1,000 flags that arent your flag. Running `tldr program_name` gives you a way simpler manual with common flags and actual examples.
