I intuitively typed saluki sniff livedata.isis.cclrc.ac.uk:31092/NDW2922_sampleEnv which sort of worked but actually listed all topics. Given how many topics exist, it would be nice for that to work and just give me the watermarks of that one topic?

| `saluki play mybroker:9092/source_topic mybroker:9092/dest_topic -t 1762209990 1762209992` - This will forward messages between the two given timestamps. |

So I think this should have worked then?

Everywhere where we support timestamps, do we also want to support passing in a human-format time and parsing it to a timestamp?
I'd kind of like to be able to saluki consume some_topic -t "2025-11-11 09:00" -m 100 to consume 100 messages after 9 o'clock on 11/11... without typing 1762851600
| `saluki consume mybroker:9092/mytopic -p 1 -o 123456 -m 10` - This will print 9 messages before (and inclusively the offset specified) offset `123456` of `mytopic` on `mybroker`, in partition 1. | ||
|
|
||
| Use the `-g` flag to go the other way, ie. in the above example to consume the 9 messages _after_ offset 123456 | ||
|
|
||
| # Install | ||
| `pip install saluki` | ||
| You can also filter out messages to specific schema(s) with the `-f` flag, like the example above for `listen`. |

Maybe this should also support timestamps - offsets are not very user friendly...

This adds
sniff,play, and filtering toconsumeandlistenas described in theREADME.md. When this is merged I'll create a new release.
