go-mtree VS snapcraft

go-mtree can take care about it. It calculates files hashes and you can use it to compare it later.

There is old unix utility called 'mtree' (there also is fully binary static compatible with mtree version on github go-mtree ) to check integrity of files. Another solution is - ZFS that do it dynamically

There is FreeBSD utility called mtree that also ported to Linux systems, that walk specified filesystem and creates hashes for all found content which later can be used to check integrity against corruption/modification. If your distribution of choice doesn't have ported version of mtree, you can use multiplatform version go-mtree that replicate the same workflow

go-mtree # Integrity

go-mtree: portable implementation of well known utility mtree) that can be used to save/test file's integrity as well directory structures. Open source, portable across most popular operation systems, no dependencies, single executable file.

There is standard utility for integrity testing mtree) that ported to linux too. Also there is multi platform version of upstream written in Go (read works everywhere from one single file) that called go-mtree

SHA1 is dead, and there is a better dedicated tool mtree(8) for such tasks (which by the way exists as implementation in Go as go-mtree ) but I believe OP wants to check versions (like fzf --version) not an integrity of files

Back in the day, I used snapd, which is similar to Mac's Homebrew.

Hopping from one distro to another with a different package manager might require some time to adapt. Using a package manager that can be installed on most distro is one way to help you get to work faster. Flatpak is one of them; other alternative are Snap, Nix or Homebrew. Flatpak is a good starter, and if you have a bunch of free time, I suggest trying Nix.

My personal favourite IDE for java is Intellej Idea. Apart from not demanding the extra extension, It was designed special for Java and Java related languages so it runs java smoothly with great compilation time. so lets install it. Make sure you have snap before installing it

Linux Mints App Store is full of GUI programs, Snap Store ist full of it, Flathub is full of it.

You are being lazy. But I recommend bringing your ass directly to snapcraft.io and reading those documents in the Learn section!!

https://github.com/snapcore/snapcraft - not sure, but looks like a building tools for snaps

Besides, there may be other ways to install them, although there doesn't seem no such Flatpak packages in Flathub. For example, some senerio to use some release channel or Docker / Podman. Additionally, when you use a different Linux distro where systemd is adopted and therefore can do Snaps (Snapd), you have another possibility.
