This tool is one of the coreutils which outputs the amount of available processor cores/threads.
Once I had to deal with the 'Raptor Lake' bug of Intel processors,
which caused segmentation faults ('Speicherzugriffsfehler') when
I compiled some projects (with the gcc).
I didn't find out how to adapt the core/thread count (this was a thing
of the apt util, not the regular MAKEFLAGS or so), and I already
knew the compilation worked with less cores/threads, so I implemented
this tiny helper (for my purposes).
Either it'll print out the real core/thread count as usual, or it can
also print a value you select for yourself by setting the NPROC
environment variable to your needs.
Unset this variable in your environment to see the original/real values again. If value is lower than 1, it'll fallback to the real ones. That's all.. :-)
I choosed regular ANSI C as programming language.
