delete all messages from all channels older than certain date

[agilangovan]

I am trying to delete all messages from all channels/groups for all users before a certain date. How would I modify this command to achieve that?

slack-cleaner --token --message --channel general --user "*" --before 20180424

Thank you.

@agilangovan you must add '--perform' to the end.

But is it possible to target all channels?

And it is not possible to remove "RSS Feed messages". It simply cannot find them.

Do we have this option to delete from all channels?
