I need a utility that
- read from stdin, split as lines
- write to stdout json object, {"cmd": "In", "lines": [lines from stdin]}
I heard jq being quite powerful, how to acheive above with jq or similar tools.
CodePudding user response:
By default, jq
reads from stdin
. The -R
flag lets you read raw input streamed linewise. Using [inputs]
in combination with the -n
flag lets you collect the lines into an array.
… | jq -Rn '{cmd: "In", lines: [inputs]}'
