From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

why would i want to delete my bash history, like to refer to my old commands (and yes i semi-regularly clear the XDG_CACHE_HOME because many apps treat them as temporary locations, STATE_HOME would be better, but i also do not remember about its existence all the time, and thank you for the librewolf script, i had something similar (i did not actually specify with this granularity though)
Yeah that is why I said either CACHE or STATE.
Before XDG_STATE_HOME there was a big question on whether log files would go on DATA or CACHE, because log files could go on either depending on how you treated them. To solve that issue XDG_STATE_HOME was created.
Ever since them the shell history gets treated with similar importance to log files. The arch wiki also suggests it for the bash history to be on STATE: https://wiki.archlinux.org/title/XDG_Base_Directory
And while XDG_CACHE_HOME is technically a temporary location, it doesn't really get used as one, one example is the very shader caches get placed in them, and I don't want to regularly clear my shader caches and wait a minute every time I start a game.
For that I use this script, which moves the cache I really want to be cleared to
/tmp: https://github.com/Samueru-sama/dotfiles/blob/main/.local/scripts/tools/tmpfs.shAnd everything else stays in
$XDG_CACHE_HOMEand I don't clear it.just 1 thing, why are you moving yay/paru to tmpdir, since they often have aur builds, and if you dont have a baller setup (i definitely do not), downloading the source and the compiles are not really temporary waste, also a general tip, dont remove browser cache also (depending upon how aggressively should the cache, like i have a slow cpu, but i got a ram upgrade and fair speed, i get almost near instantaneous load time when going to pages i have cached(for configuration, please check betterfox speed setup))
I have 16 GiB of mem + zram. Nothing makes it run out of mem.
Zram gives me some insane compression ratios. Like I cannot get the system to run out of mem doing everything that I normally do at once.
Also that is old, I don't really use the aur anymore. The only aur package that I have installed is
downgradeand that is used to troubleshoot issues with the official packages lol.I also have the pacman cache in tmpfs, since I use btrfs snapshots for restoring.
Also my web pages and everything load just fine. I did mostly to reduce unnecessary writes to disk, the Gentoo wiki suggest moving the whole
$XDG_CACHE_HOMEto tmpfs which I think is extreme lolAlso my browser cache is not fully being cleared, notice that at the end of the script I have some syncing going on with rsync.
