Thank you for the page @xiaolong-666! I've left a comment below for you to review.

@xiaolong-666 this page is very nicely written! Instead of parenthetically putting the flags in the example descriptions, please remove those and change the short flags to long flags in the commands, including the ones for ssh.

For example -azvhP should be --archive --compress --verbose --human-readable --partial --progress.

@bl-ue: regarding rsync's short arguments, we're tried to offset that with the description in english:

- Transfer file in [a]rchive (to preserve attributes) and compressed ([z]ipped) mode with [v]erbose and [h]uman-readable [P]rogress

...obiously, this syntax doesn't translate into other languages though, which is rather awkward. But in this particular instance expanding on all the short arguments would result in an extremely long command which should be difficult to type, so I'm not sure.

[bl-ue]

Then maybe we should remove some of the options entirely. I think it would be best to use long options and save description space for something else.

Hi @xiaolong-666, it looks like you missed some periods...

[bl-ue]

It looks like you delete a necessary newline—maybe you were confused by @navarroaxel's comment? Apply my suggestion below to fix it.

[bl-ue]

Darn, now it looks like there's two newlines...let me take a look...

[bl-ue]

There we go. LGTM!

@bl-ue This format detection is not smart... ha ha
