FORMATS
RIP a.out
Archaic file format looks set to disappear from Linux.
After 30 years, it looks like a.out support will finally be removed from Linux. While the once-popular file format (which was replaced by ELF in the mid-1990s) was deprecated in 2019, a patch has been proposed (https://bit.ly/lxf286patch) to remove a.out support completely from the kernel.
