I'm using the jq tool to handle some JSON in bash. 
Just one problem, while using this line:

 PB_ACL="acl="`echo $IMGREQ | jq -r'.data.acl'`

Result:

 echo $PB_ACL // acl=

The expected value jq has to filter out is: "acl":"public-read"
But it's not working now. I think it has to to with the dash (-) symbol.

How do I escape such incoming string data?
