The PUT command in rest-shell keeps on asking about --data parameter. My json is big and need to get it from file. Following command does not work with the error mentioned.

> put --from /Users/sudhir/json/t.json
http://localhost:8080/tortlets/tortlets/json:> put --from /Users/sudhir/json/t.json
You should specify option (--, --data, --follow, --output) for this command

Also tried.
http://localhost:8080/tortlets/tortlets/json:> put --data "" --from /Users/sudhir/json/t.json
You should specify value for option 'data' for this command
http://localhost:8080/tortlets/tortlets/json:>
