  • Here is on that I actually don’t use, but want to use it in scripts. It is meant to be used by piping it. It’s simple branch with user interaction. I don’t even know if there is a standard program doing exactly that already.

    # usage: yesno [prompt]
    # example:
    #   yesno && echo yes
    #   yesno Continue? && echo yes || echo no
    yesno() {
        local prompt
        local answer
        if [[ "${#}" -gt 0 ]]; then
            prompt="${*} "
        fi
        read -rp "${prompt}[y/n]: " answer
        case "${answer}" in
        [Yy0]*) return 0 ;;
        [Nn1]*) return 1 ;;
        *) return 2 ;;
        esac
    }
    

  • For the newer version of program, that’s why we have the $PATH. You put your program into one of the directories that is in your $PATH variable, then you can access your script or program from any of these like a regular program. Check the directories with echo "$PATH" | tr ':' '\n'

    My custom scripts and programs directory is “~/.local/bin”, but it has to be in the $PATH variable too. Every program and script i put there can be run like any other program. You don’t even need an alias for this specific program in example.


  • I’m not sure what you mean with the question. If you have any alias like alias rm='ls -l' in your .bashrc in example, then you cannot use the original command rm anymore, as it is aliased to something else. I’m speaking about the terminal, when you enter the command. However, if you put a backslash in front of it like \rm in the terminal, then the alias for it is ignored and the original command is executed instead.

    Edit: Made a more clear alias example.




  • i also have the chmod one, but mine is named just x:

    alias x='chmod +x'
    

    I also have the yt-dlp "$(wl-paste)" one, but its build around a custom script. So sharing it here makes no sense. Its funny how often we do same thing in different ways (extracting or creating archives in example). Often aliases get development into function and then they turn into scripts. For some of the more simple aliases, here a selection:

    alias f='fastfetch -l none'
    alias vim='nvim'
    alias baloo='balooctl6'
    


  • With how many new Linux users we get recently, I don’t like this joke at all without a disclaimer. Yes yes, its your own fault if you execute commands without knowing what it does. But that should not punish someone by deleting every important personal file on the system.

    In case any reader don’t know, rm is a command to delete files and with the option rm -r everything recursively will be searched and deleted on the filesystem. Option -f (here bundled together as -rf) will never prompt for any non existing file. The / here means start from the root directory of you system, which in combination with the recursive option will search down everything, home folder included, and find every file. Normally this is protected todo, but the extra option --no-preserve-root makes sure this command is run with the root / path.

    Haha I know its funny. Until someone loses data. Jokes like these are harmful in my opinion.


  • I love what hobbyist are doing with these custom hardware builds. On the picture the form somehow reminds me back to the Dreamcast controller from 2000, if someone remembers. It did not have trackpad, but the form looked similar uncomfortable. But it felt great in the hands. And knowing how great the Deck in the hands feel, I am sure his creation would be very nice to hold. It’s just the image does not imply this for me.

    Very impressive he build his own trackpads, that fit the specifications of the Deck. There are no ready to use Deck trackpads one can buy at all! The entire thing is published as Open Source project to build your own. I cannot. Maybe a company takes this and makes a product to sell. I would totally buy a good and functioning one for a premium price.

    But I predict Valve will 1 year before the Steam Deck 2 hopefully release an official Steam Controller 2. A man can only dream (unless you are talented like that guy)…









    • get a dock
    • attach keyboard and mouse on the dock and connect the dock to a monitor
    • go into desktop mode on your Steam Deck
    • open up Discover and install applications

    Basically a full fledged PC. There are some limitations, but for the most part you are able to code on it. You can write text and source code files, edit videos, edit images, browse the web with regular Firefox and so on. I can’t say if the Steam Deck works well creating games with Godot, but technically it shouldn’t stop you from trying.





  • What negotiation? I have a hard time to follow what you mean. Which operating system does turn off when shutting down? If it does not, then either its configured to do so (or not to) or there is an issue that needs to be handled and resolved. You don’t want your PC turn off immediately, so it can do stuff that is needed (such as wait for all drives to write the data) or remove temporary files and unmount drives and so on. Otherwise an instant turn off is equivalent to a crash (including all background services and running applications, losing data, corrupting drives…).
