zzbox
zzbox is intended to be a core collection of Unix utilities that pedantically follow POSIX.1-2024.
What do we mean by pedantic?
For one example, check the
Exit Status section of the specification for false:
The false utility shall always exit with a value between 1 and 125, inclusive.
Most implementations of false will always exit 1.
zzbox's false interprets the specification literally,
and it returns a random value in that range.
How do I use it?
Build it from source for now (zig build with the current master branch of Zig).
Use it like BusyBox
or toybox:
if the basename matches a supported utility,
it is as though you executed that utility directly.
That is, if the zzbox binary is /bin/cat
or if /bin/cat is a symlink to the zzbox binary,
then the executable acts like cat.
Otherwise, the first positional argument is treated as the name of the utility to execute.
Why?
- I have, for a long time, thought it would be interesting to write several Unix utilities from scratch.
- This looked like a good excuse to try out Zig.
