How do I delete all data from a Solr collection?

I'd like to delete all of the indexed data in my Solr collection, preferably via a shell command on one of the nodes itself. How can I do that?

you can use below command for command prompt

curl http://<ip_address>:8983/solr/<collection_name>/update --data '<delete><query>*:*</query></delete>' -H 'Content-type:text/xml; charset=utf-8';

If you have access to the shell, use the solrctl command with the following options:

solrctl collection --deletedocs <collection-name>

Here's the full usage output from solrctl --help for reference:

usage: /usr/bin/solrctl [options] command [command-arg] [command [command-arg]] ...

Options:
    --solr solr_uri
    --zk   zk_ensemble
    --help
    --quiet

Commands:
    init        [--force]

    instancedir [--generate path]
                [--create name path]
                [--update name path]
                [--get name path]
                [--delete name]
                [--list]

    collection  [--create name -s <numShards>
                              [-c <collection.configName>]
                              [-r <replicationFactor>]
                              [-m <maxShardsPerNode>]
                              [-n <createNodeSet>]]
                [--delete name]
                [--reload name]
                [--stat name]
                [--deletedocs name]
                [--list]

    core        [--create name [-p name=value]...]
                [--reload name]
                [--unload name]
                [--status name]

If you don't have direct access, you can use Solr's update services as described here, here, and here.
