Description:

Currently when running ipfs dht findprovs it'll continue until a timeout or finding 20 peers. It would be helpful if we could configure the command not return just because it found 20 peers. In addition, would be helpful to be able to configure the amount of time it'll search as well.

There is global ipfs option, timeout that causes the command to timeout after some time.

Example: ipfs --timeout=1s dht findprovs /ipfs/QmVZxZgdnZ8h2L7V5bhLsE4CvAmAaGyLjBhFJHYigPE9X1

Needs to be documented -- it's not in ipfs --help

[faddat]

is this what one would use to identify the peers serving a given file?

[Kubuxu]

Yes findprovs can be used for that.

It should be very easy to do, just making https://github.com/ipfs/go-ipfs/blob/master/core/commands/dht.go#L162 a CLI parameter and adding some tests for it.
