Someone has to explain how rm, which doesn’t allocate any memory (as far as I can tell), isn’t memory safe ?
If I cant remember what dir I'm in, then rm is mot very memory safe is it?
[edit: spelling]

I guess
vpr -xwould be memory-safe that way then. ;)I don't know whether
rmis memory-safe or not, butvpris. By 'memory-safe alternative' I meant that this alternative is memory-safe, but not thatrmisn't.Reminds me of when they started printing "vegan" and "gluten free" on water bottles.
ive heard they've even started putting halal water in my taps!
In GNU coreutils the implementation of
rmdoesn't allocate memory however I believe alternative implementations do.Here's an example from the OpenBSD source code - https://github.com/openbsd/src/blob/222e275fb89ffb67abe0726dee2b107220092dc3/bin/rm/rm.c#L335
Presumably other *BSDs use something similar? Didn't check out FreeBSD or anything.
Edit: So I suppose if you are using a BSD-type system (maybe including macOS?), and memory safety was important to you (to the point of extreme paranoia), then you might want to look into this rust project. Or just use the GNU implementation.
