Ishan Chattopadhyaya commented on SOLR-13682:
---------------------------------------------

bq. I'm +1 on starting a work towards making all bin/solr commands runnable 
externally and to make the tool itself portable so you can take it with you to 
any machine with bash and Java.
+1

My 2 cents on -c vs. -url: I would prefer -url (which will work on all cases, 
local as well as external cluster). Imagine a situation where the export is 
actually running against an alias, not a real collection. Having -c do the 
export would be misleading in that case. A URL will be valid in both cases.
