Please, keep doing it as a regular series on the channel until there is nothing more to explain (so, forever :o)!

    I'm an experienced Linux user with quite a bit more than 15 years experience, and in kind of knew that fuser existed but have always fiddled with lsof to get things like that done - and often got frustrated. I will now use fuser for all of my laod needs because now I know it's easier and better - *thank you Veronica*

    Veronica, I find your style, your humour (which I really appreciate), and the hard work you put into your editing -- well, I find that I am absorbing what you are teaching. Rare that I can sit back and be passive and just watch a video and just absorb. Thank you for doing what you are doing.
    If imitation is the greatest form of flattery, than consider yourself being very flattered.
    Your pacing is fantastic. No, not fantastic. Sublime. You slow down, but not in a monotone way, and not in a way that sounds like you are going at 3/4 speed, and not in a way that sounds like you are talking down to us. It must be harmonics or something because your pace of talking matches my pace of listening. I think you have a special ability to slow down your talking, without going into a monotone. The flip side would be the ability to talk faster without sounding like you just went to 1.5x. Something that you do well, that I have taken especial note of, is that you pause. You take that extra beat of pausing, without sounding like you are creating white space. I do not have that talent.
    The funny thing about you shooting your videos in your unfinished basement is that there are no distractions. I think you should earmark a piece of your basement as "The Stud Room" (even if it is not really a room), and continue shooting your videos there. No LED lights, no worrying about having the right wallpaper on your screens, no worrying about keeping it clean, no worrying about what is on the wall.
    These small "L'il" videos are brilliant, and effective.
    I appreciate you recommending other RUclips creators. They should be recommending you, not the other way around.
    I am a "lazy liker", and have been remiss "liking" your videos. I will rectify this in the future with your videos.
    All my best from Toronto, Canada.

  • @MARK01986
    @MARK01986 3 месяца назад +1

    At my first job we used to use fuser.
    It was not allowed for the same user to be logged in at the same time.
    The problem was when the user was left hanging in the system and could not log in again because there was already a session started.
    We used a fuser -ku /dev/TTY
    Usually, we looked for the user's TTY within a script and passed it as a parameter to the fuser.
    By the way, I love the way you Speak English.!!!!!!

  • @alexhajnal107
    @alexhajnal107 11 месяцев назад +4

    I'm a seasoned Linux and Unix user (going back to the '90s), well over a decade of that as a sysadmin. I like watching these "basics" videos (for all kinds of topics) to get a fresh perspective on things¹. You did a really good job with this video!
    ¹ For example, simply out of habit I've usually used *lsof -n | grep PATH* . This has worked fine in the past but this is severely broken² on the latest Ubuntu release. I've been planning to look into this but as you mentioned *fuser* can be a good substitute in a lot of cases.
    ² For some reason (I suspect it's something to do with *snap* , _et al._ ) there is a substantial delay before *lsof* (without *-p* ) outputs anything. For example, on my current desktop *lsof* takes a whopping 30 seconds before outputting anything whilst *fuser -v PATH* only takes ~220 ms. (Running *lsof -p PID* runs fast, ~130 ms.)

      ​@@VeronicaExplains but Linux or rather any OS should just give you an option to 'Show details' or 'Expand' on the UI to get more information about the processes or files open and maybe even an 'X' button to close them directly from that one pop-up. Someone should create a PR for it. I could have if I knew anything about it (I am an Android app developer).
