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.

This is not a defense against bad actor, but defense against bugs in bash script, which is quite common. Another idea is to introduce a new trash command
xdg-trash
to replacerm
. But both of these cannot stop malicious actors removing your file.I think even if we have a security suite, it is unlikely to detect bad actor recursively enumerating the file and delete them one by one, until many files were irrversably lost.
Antivirus has never been a proper way to achieve security, I think the proper way to defend against offensive
rm
is probably sandboxing.
