jq: How to output quotes on raw output on windows

问题

Using raw output I have to quote some values of the output.

echo [{"a" : "b"}] | jq-win64.exe --raw-output ".[] | \"Result is: \" + .a + \".\""

generates

Result is: b.

but how can I generate

Result is: "b".

Unfortunately it has to run on Windows called from inside a CMD file.

回答1:

You need to escape the slashes to escape a "

$ echo [{"a" : "b"}] | jq-win64.exe --raw-output ".[] | \"Result is: \\\"\" + .a + \"\\\".\""
Result is: "b".

回答2:

A hacky workaround with less backslashing could be:

jq -r ".[] | \"Result is: \" + (.a|tojson)"

[REVISED to reflect OP goal.]

回答3:

Since you're trying to output double quotes in a double quoted string, you need to escape the inner quotes. And to escape the inner quotes, you need to also escape the escaping backslashes. So a literal double quote would have to be entered as \\\". You can do this a little cleaner by using string interpolation instead of regular string concatenation.

jq -r ".[] | \"Result is: \\\"\(.a)\\\".\""
