I'm trying to convert an object that looks like this: { "123" : "abc", "231" : "dbh", "452" : "xyz" } To csv that looks like this: "123","abc" "231","dbh" "452","xyz" I would prefer to use the command line tool jq but can't seem to figure out how to do the assignment.

I have a Linux server with Redis installed and I want to connect to it via command line from my local Linux machine. Is it possible to install redis-cli only (without redis-server and other tools)?
