Can somebody explain why they are using libc in the first place?
Because it's a rust implementation of coreutils, and not a rust implementation of coreutils and libc?
But why is libc necessary in the first place? Are the functions not provided by the stdlib of rust?
No, the Rust standard library only contains functions useful for standard Rust, not POSIX/Linux user-space -specific functionality from libc.
