You totally missed an opportunity for that classic linux joke:

$ love
love not found
$ happiness
happiness not found
$ kill
you must specify whom to kill

The Greatest Thumbnail That's Ever Lived

[Dsamuell]

Opening fireship's videos are always like:
Come for information
Stay for the punchlines

[bjvmdxv]

"if you have few years to spare you can learn Vim and if you have no life at all you could try emacs", damn that got me

[lucasvella]

In your 96% figure, I think you grossly underestimated the number of people watching this video on their Android devices.

[eliovalentinoancivillarroe]

I'm 4 years using linux right now, and I didn't knew the existence of stat command. Always you can learn new staff from this channel. Thanks for the nice video!!!

[hclyrics]

This video cured my Linux imposter syndrome. I recognized and understood way more than I thought I would. Another Fireship banger, for sure.

[donalshijan]

This is why fireship is the best online educator / content creator, he taught everything that there is to know about linux and shell commands in just a 12 min video when others are selling month long courses.

[vannear]

Everytime I watch a intro/beginner's guide video for linux/bash cmds, there's something new I haven't used before

[franciscomagalhaes]

I think this is your best video yet, and I've followed you for years. Very entertaining and informative. Well done.

[mrt_]

4:10 Correction, as you can read in the title of the manpage: "touch" simply changes file timestamps. Though this has the side effect of creating an empty file if the path given isn't an existing file, so it often gets used to create new files.

[thahrimdon]

This was actually ridiculously informative. Wow. Great video fireship. Been getting into Linux and thought I’d know most if not all but there were definitely a few I didn’t know about. Keep doing this!

[JaceComix]

This was low-key a really good explanation of a lot of stuff that I either didn't know or struggled to figure out on my own.

[azatecas]

statistically, all fireship viewers have tried linux

[tristanreid]

On that chown stuff, when he said the stuff about 7s, it can be kind of cryptic where those numbers come from. The idea is that 7 in binary is 111. Those 3 ones are rwx (read/write/execute), the 1 means that they're all turned on. A 000 would be all turned off, or another example is 6, which in binary is 110, so read & write are turned on, but execute is turned off. Read-only is 4, which in binary is 100, so only the read bit is turned on.

[rogero]

I don't know if I have time to learn linux right now, but your courses actually look like a great idea, because you're wonderfully enunciated for this sort of content. If I do find time, that's where I'll go.

[dudeabideth]

I bet that the only people who watched this full are who use Linux day to day and know it well .

[azufendusgarendum]

3:21 "open up the terminal which is a graphical user interface"

🤣

[luay_kelani]

I always dreamt of saying this on this channel and finally:

I use Arch Btw.
