    Thumbs up for cats in the video. In fact, I will thumbs up every video with cat photos on it, even though I already thumbs up all the videos. But, it's well known that cat photos increase your traffic 60% of the time, every time.

    Using cat in combination with grep in stead of just using grep on a file is often referred to as "cat abuse"!
    The more you know :)

    Very nice. I recently learned about "tac",which is cat backwards. It seems a joke, but it works

    I just took the plunge using Arch for my daily driver. Most of my career was Windows. Little things like this are refreshers of what I partially picked up from the Linux teams, but now have a much more firm understanding. Thanks!

    Good informative video
    I found two more use cases
    cat /dev/null > # clears all the contents of the file
    tac # displays the file in the reverse order

    I don't understand why people subscribe to these services. I have a VM of any OS I want on my Mac. Kali/Win10/Whois, etc. I get it takes wayyy less resources, but you get it basically for free, and the power of the entire OS. But I just use it to learn through my degree. I guess for DevOps it'd be different though.

    A good followup would be to show bash's "heredoc" feature (I'm reminded of this because I just used it with cat to extend an existing file). Looks something like this:
    cat >> old_file

    I love cats and I love Linux, but showing pictures of cats during the tutorial was a bit distracting for me. Just an opinion, but still a great video.

    cat has problems with finding files with spaces in their name. I tried (as root) cat /etc/NetworkManager/system-connections/Auto ssid.nmconnection and it was "cat: /etc/NetworkManager/system-connections/Auto: No such file or directory
    cat: ssid.nmconnection: No such file or directory" but of course ls -l found them with no problem. I tried quotes and Auto\ ssid.nmconnection, but no joy. I installed batcat and it worked finally.

    Piping cat into grep, wc, etc. is pointless most of the time as these commands can take filenames directly. To view file content in the shell it's better to use less.

    This was bad for both cat lovers and developers. Images popping up ruin the experience and you don’t really get the benefit of looking at cats 👎
