Write that down
TIL what dnf is finally.
Did not finish. Used a lot in racing after an accident…oh wait…
I’m not seeing any smitty love
I do both. If I know exactly what I want to install, I’ll install it from the terminal because it’s often more direct. If I go “I need an app that does thing, what’s available?”
paruYay!
Non of those.
sudo zypper dupAnother on Tumbleweed?? Hi!
indeed :)

LoL
mommy install <package> --sudoDuh. Why do you think I switched to Linux the moment I learned it existed
This one hurts.
I don’t get it. Looks like a script that runs all these things, but I don’t get the one dollar.
The
$1is a positional variable. So if you run./script.sh arg1$1 would be arg1 in that example, $0 would be the ./script.sh. It’s the simplest way to pass an argument to a script.So… huh? What role does this play, since all the lines in the picture have $1? If you run it with arg1, won’t it run them all? And if you left out arg1 and also didn’t add $1 to each line, wouldn’t it also just run all of them?
So the joke is, you’ve got something you want to install, be it a Python module, Java library, steam game, desktop application, whatever. You want it installed, figuring out which package manager has it and remembering the exact command syntax starts getting to be a pain, so just use this script to try installing it from a variety of sources.
You would evoke it by running
./install.sh packageand it will replace all instances of $1 with the string “package” at runtime. The ampersand at the end of each line will run that line as a separate background process rather than in the foreground process, so effectively this will attempt to install “package” or whatever you put in as an argument from a half dozen sources simultaneously in parallel.These include the old and new Python package managers, the old and new Red Hat package managers, debian/Ubuntu’s APT with and without sudo, cloning a git repo and building from source, and the icing on the cake is curling directly into bash.
Don’t curl directly into bash. You’ll catch genital rabies.
Remember that this is an XKCD comic, it’s a joke. The alt-text says “The failures usually don’t hurt anything and if it installs multiple versions it increases the chance one of them is right. (the ‘yes’ command and ‘2>/dev/null’ are recommended additions.)” “Yes” is a bash command that will spam ‘y’ in the terminal, the point of it is to answer yes to any questions an automated system asks, and 2>/dev/null will stop it from displaying errors. These add an even deeper level of Yolo-ing.
Ah alright. Pretty sure I get it now. Thank you for explaining!
If you run it with arg1, won’t it run them all?
Yes, that is the intention. When you’re following some guide online and it requires you use some “software”, you may not know how to install that software.
This install.sh script tries package managers, because one of them will probably work. Others will fail.
For example, installing numpy (python package): pip install succeeds and all the other ones (hopefully) fail.
Installing libcurl4-openssl-dev (curl with openssl library file): apt-get install works and all other ones (hopefully) fails.
Longer and more thorough explanation:
https://www.explainxkcd.com/wiki/index.php/1654:_Universal_Install_Script
Never thought about it, but wouldn’t that just fail after the first one it fails to find? I think most install commands return nonzero if nothing is installed
Should probably use or instead of and
Nope, this launches all those commands in parallel. Logical and is
&&.
ujust update
I use Bazzite BTW
I’ll keep making Debian users aware that they can do it all in one command since Trixie.
sudo apt --update --autoremove --with-new-pkgs upgradeFirst they changed apt-get to apt. Now this.
I can’t keep up with all the sudden changes.
I also like topgrade for this.
I love you. Thanks for sharing 😌
Ok now that’s pretty good. Can we use this with dist-upgrade/full-upgrade?
Yes, it’s a command from apt-get that apt only passes through:
–auto-remove, --autoremove
If the command is either install or remove, then this option acts like running the autoremove command, removing unused dependency packages. Configuration Item: APT::Get::AutomaticRemove.–with-new-pkgs
Allow installing new packages when used in conjunction with upgrade. This is useful if the update of an installed package requires new dependencies to be installed. Instead of holding the package back upgrade will upgrade the package and install the new dependencies. Note that upgrade with this option will never remove packages, only allow adding new ones. Configuration Item: APT::Get::Upgrade-Allow-New.-U, --update
Run the update command before the specified command. This is supported for commands installing, removing, or upgrading packages such as install, remove, safe-upgrade, full-upgrade. This can be useful to ensure a command always installs the latest versions, or, in combination with the –snapshot option to make sure the snapshot is present when install is being run.Excellent! Feel like I’ve been continuously learning new things about Aptitude for the better part of 20 years lmao
sudo apt update && sudo apt upgrade -y && sudo flatpak update -yflatpak is only “flatpak update -y” from what i remember
Sure, if you want to type your password 17 times.
it’s not supposed to ask for any password at all
Aren’t you supposed to do
apt full-upgradeinstead ofapt upgrade?Also wtf is
pkconfor?It is what Sailfish OS uses as default package manager even though it can also use zypper.
For extra fun, there’s also
dist-upgrade
If that’s the game we’re gonna play:
yay
I’m old enough to
yum
RIP in peace yellow dog linux
Yum was used on way more than Yellow Dog Linux. CentOS, Fedora, RHEL, etc all did
I was annoyed when i discovered cachyos used paru.
I understand defaulting to prompting a code review is a good idea, especially now, but i was very used to typing yay (yes I installed yay instead of making an alias)
paru is based, Rust >> Go lol
