curl "http://index.websolr.com/solr/a0b1c2d3/update?commit=true" -H "Content-Type: text/xml" --data-binary '<delete><query>*:*</query></delete>'

I'm amused at the traction this little gist is getting on Google! I would be remiss not to point out that six+ years later I'm still helping thousands of companies on a daily basis with their search index management, by providing managed Solr as a service over at Websolr, and hosted Elasticsearch at Bonsai. Check us out if you'd like an expert helping hand at Solr and Elasticsearch hosting, ops and support!

Fire this in the browser
For deletion:
http://host:port/solr/core/update?stream.body=:&commit=true
For schema reload:
http://host:port/solr/admin/cores?action=RELOAD&core=core
Replace
host: Host name
port: Port number
core: Core Name

Through curl :

curl http://host:port/solr/core_name/update?commit=true -H "Content-Type: text/xml" --data-binary `'<delete><query>*:*</query></delete>'`

Through browser :

http://host:port/solr/core_name/update?commit=true&stream.body=<delete><query>*:*</query></delete>

single core:
curl http://localhost:8080/solr/update?commit=true -H "Content-Type: text/xml" --data-binary ':'
multiple core:
curl http://localhost:8080/solr/core_name/update?commit=true -H "Content-Type: text/xml" --data-binary ':'

None of the commands above worked for me.
LE: http://localhost:8983/solr/core_name/update?commit=true&stream.body=%3Cdelete%3E%3Cquery%3E*%3A*%3C/query%3E%3C/delete%3E this worked 💃

The command by objectivePinta is shut off at least in Solr version 7.2.0 (in the out of the box configuration). However, the curl - solution of SainathSharmadha worked (for me) in this version.

Solr version 7.2.0 doesn't allow stream body anymore.
However, SainathSharmadha code will work by using binary data type.
If you're using the Post tool provided by solr:
bin/post -c core_name -type text/xml -out yes -d $'<delete><query>*:*</query></delete>'
