I was trying to find out how to get human readable timestamps from my shell history. They gave me this crazy script. It worked but it was super slow. Later I learned you could do history -i.
Turns out, a lot of the problems in nixland were solved 3 decades ago with a single flag of built-in utilities.
Apart from me not reading the manual (or skimming to quick) I might have asked the LLM to check the history file rather than the command. Idk. I honestly didn't know the history command did anything different than just printing the history file
man 3 history
info history
Also, your .bashrc file in your $HOME Dir contains env variables you can set to modify the behaviors of the history function.
I really need to alias man to man -a.
I
man -k
a lot.What's that?
The option
-k
for the commandman
allows you to search the manual pages for specific terms.Similar to the command
apropos

Oh I need to learn more
Honestly, I thought I knew lots.
Then, one day, I decided to read
man intro
Then I knew I knew I didn't know much.
I still don't.
But I now have a much better grasp of what/how.
I didn't know about this. Thank you for the knowledge fellow human!
I don't run crazy scripts in my machine. If I don't understand it's not safe enough.
That's how you get pranked and hacked
