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.

I think it's absurd that most distros have no tools whatsoever for doing regular checksums of their own files. Windows certainly got that part right IMO.
I’m double checking this myself now, but there are plenty of tools (debsum) they’re just not part of the default implementation as of last time I looked.
Right, I'm talking about like periodic or real-time scanning and alerting, which DISM/SFC on windows does.
i'm almost 100% that debsums on apt stuff and the --verify flag in rpm distros do what sfc did. (kinda, debsums and --verify check against a list of checksums from the repo, i'm pretty sure sfc cracks open an actual known version of the files and compares em with whats on disk)
idk what dism does.
