`du` pages repeated

[witt-bit]

common/du.md and osx/du.md are highly redundant and have the same usage. It is recommended to merge them.

And there are some problems with the output of tldr du.

tldr du                                                                                                       ✔  4s 

  - List the sizes of a directory and any subdirectories, in the given unit (B/KiB/MiB):
    du -b|k|m path/to/directory

  - List the sizes of a directory and any subdirectories, in human-readable form (i.e. auto-selecting the appropriate unit for each size):
    du -h path/to/directory

  - Show the size of a single directory, in human-readable units:
    du -sh path/to/directory

  - List the human-readable sizes of a directory and of all the files and directories within it:
    du -ah path/to/directory

  - List the human-readable sizes of a directory and any subdirectories, up to N levels deep:
    du -h --max-depth=N path/to/directory

  - List the human-readable size of all `.jpg` files in subdirectories of the current directory, and show a cumulative total at the end:
    du -ch */*.jpg

  - List all files and directories (including hidden ones) above a certain [t]hreshold size (useful for investigating what is actually taking up the space):
    du --all --human-readable --threshold 1G|1024M|1048576K .[^.]* *

Hi. Thanks for creating the issue. I don't think we should merge these pages, as the commands have different options. The common page uses b|k|m, while the OSX one uses k|m|g in the first example.
Also, we have multiple situations where pages are almost the same but still haven't been merged, for example, 7z, 7za, and 7zr.

I found some differences, but Found 3 pages with the same name under the platforms: xxx needs improvement

That's an issue with the client you're using, please create an issue in the client's repository.

In general it's annoying because coreutils commands will usually have more flags than OSX commands which are based on ancient BSD utils iirc
