day 01
learning linux bash is like learning a language.
sometimes it whispers. sometimes it yells.
today, i focused on 5 low noise, high-signal commands that quietly flex terminal mastery.
file open-source.txt
wanna know what a file really is?
don’t trust the extension ask the kernel.
file is like that friend who always knows what’s inside your mystery bag. (think: dora the explorer with strace energy.)
type grep
shell: “is this a real command or just some alias magic?”
type = the bouncer at the club of your terminal. no fake ids. no nonsense.
ls
the classic. the god.
shows you what’s inside a directory.
but don’t be fooled it’s not just “list stuff.”
it’s the gateway drug to flags like -alh, --color, and beyond.
history | tail -n 5
because sometimes, your past self was smarter than you think.
history is like time travel for developers. revisit your genius (or your chaos).
clear
wipes everything. no questions asked.
it’s like that dad who said he’d go buy milk. never came back. clean exit.
but hey, at least the terminal looks peaceful now.
đź’Ş doing this to build real muscle for my az-204 prep.
not just for the cert but to actually get it.
