Automatically setting jobs (-j) flag for a multicore machine?

Question

I have a Makefile on a machine that has a ton of cores in it, but I always seem to forget to write -jX when compiling my project and it takes way longer than it

Answer 1

I would just put

alias make='make -j'

in ~/.profile or ~/.bashrc.

According to the manual:

If there is nothing looking like an integer after the ‘-j’ option, there is no limit on the number of job slots.
