How do you split this into different files?

[dev-ardi]

This compiles to a single binary, and then you need to pass the name of the util. If I want to call cat I need to call coreutils cat or create a script for each util I want to use.

Is there a way to build each util to its own binary?

Read the fine manual :) https://github.com/uutils/coreutils#gnu-make

[dev-ardi]

my bad!! I completely missed that in the manual, I only skimmed that part

[dev-ardi]

how do you build all? pass a glob to cargo?

[sylvestre]

yeah, the make knows the list of programs and call cargo the right way
