I'm waiting for initial feature approval before adding tests/making a PR to the docs repo

Still not sure it should be there. But leaving for others to decide.

@shtripat @harshavardhana Hello ! Would it be possible to review this PR please ? Thank you

I am confused about the value add of this feature. If we really need such a thing, we can use --json output and then sort as and when needed. Something like mc ls ALIAS/BUCKET -r --json | jq -s 'sort_by(.size) | .[] | {key, size}'

[iTrooz]

We could do that, but but the --json | jq -s 'sort_by(.size) | .[] | {key, size}' part is a bit cumbersome (I personally wouldn't be able to pull it off in a reasonable time), which is why I added the --sort. It is purely a QoL feature

IIUC this kind of sorting is needed when we are programmatically processing the output and --json is meant to be used for this purpose. But lets hear from Harsha as well.

My use case was "I want to see what the biggest files are in this bucket" (not in the context of a script, purely me out of curiosity)
Maybe there is already a way to do that that I missed ?

But lets hear from Harsha as well.

Ok !
