[claudex]

This seems already implemented https://github.com/uutils/procps/blob/main/src/uu/free/src/free.rs#L84

is it correctly implement? i am not sure :)

I don't see the difference, maybe I'm missing something:

$ /bin/free -w
               total        used        free      shared     buffers       cache   available
Mem:        64992236    17611088     1450392     1235384      444840    47442396    47381148
Swap:        1048572        4864     1043708
$ target/release/free -w
               total        used        free      shared     buffers       cache   available

I think this feature should be implemented correctly
