@Krysztal112233 #6482 fixes the clippy errors in shuf.rs but there is also a clippy error shown in your code, see https://github.com/uutils/coreutils/actions/runs/9580690912/job/26415846170?pr=6483

the coverage isn't ideal: "62.08% of diff hit (target 87.45%) " could you please improve it a bit ? thanks

[Krysztal112233]

I need some help XP. @sylvestre @cakebaker

It looks like Codecov is not testing the tests in the process.rs file correctly, what should I do?

[sylvestre]

it isn't a coverage issue but a test:
