How to escape single quotes into double quotes into single quotes

Question

Here is an example of command line that fit this description :

curl  http://dumbdomain.com/solr/collection2/update/json -H
\'Content-type:applic         


        

Answer 1

An usual workaround in such cases is to put the data in a file and post.

$ cat post.json
{ "add": { "doc": { "uid": "79729", "text" : "I've got your number"} } }

And then invoke:

curl -H "Content-type:application/json" --data @post.json http://dumbdomain.com/solr/collection2/update/json

This would obviate the need of escaping any quotes in the json.
