Escape Single Quotes Ansible 2.1

Question

Using Ansible 2.1,

ansible all -i 127.0.0.1, -m lineinfile   -a    "dest=/etc/engine/engine.json state=present regexp=\"rpc_json\" line='\"rpc_json\": \"127.0.0.1:54321\"'," 

That commands works but adds

'"rpc_json": "127.0.0.1:54321"',

Please how do i remove the single quote, so i can have

"rpc_json": "127.0.0.1:54321",

Answer 1

It is more bash question than ansible:

ansible all -i 127.0.0.1, -m lineinfile -a 'dest=/etc/engine/engine.json state=present regexp=rpc_json line='\''"rpc_json": "127.0.0.1:54321",'\'

In '\'' first ' closes string, then \' glues escaped single quote, then ' starts next string to be glued.
