How to clear all cache

and another question, how to clear all cache or redundant or junk in fedora? what command line most of apps i install with .rpm extension

best would be to use dnf install , which tries to resolve all dependencies. you can also use rpm -i install rpms but rpm will not try to solve dependencies automatically.

please explain what you are trying to achieve…

Hi, here’s some sauce:

sudo dnf clean all

Also, read the post-upgrade section here if you really have OCD. =^)

like in windows junk files temporary files prefetch, in linux they have same thing? if have how to remove them to optimize my desktop

thankyou for this, i’ll read this☺️

Fedora has had tmpfs for a long while. It does a much better job of not writing junk by default.

the temp folder resides in RAM, so when you shut down your computer, all temp files are gone. Most app caches are located in your home directory - no need to delete them.

thankyou for clearing it up, and sorry of i have many questions. This is my first linux distro i use☺️

This makes no sense. Downloaded rpms are automatically deleted once the install process succeeds and the repository metadata is re-downloaded on every dnf update process.

You don’t gain anything by running this command. I recommend using it only if dnf runs into problems.

This is true. It’s a one-line nuke command. But learning that updates take forever after doing this is just part of the natural learning process IMO.

Don’t be sorry, this place explicitly is for async communication.

this fedora distro and forum is so good. I think I made a good choice for what distro I’ll use :joy:

re-downloading if it’s duplicated it will automatically delete? for example i run that command for multiple times even though not needed

it will just update the repo metadata. don’t worry, your are not wasting any hard disk space by not running dnf clean all

okay thankyouuu for both of you. Appreciated

You can also keep your metadata while safely deleting the unused rpm packages. How can you do that?

Try:

$ man dnf > /tmp/dnf.txt

Now open /tmp/dnf.txt in your favorite editor, search for “Command: clean”, and put some wrinkles on that grey-matter.
