$ cat some.json | j '_.map(x => x.timestamp)' --file pre.js --tab 2
$ cat some.json | j '_.map(x => x.timestamp)' > some.json
$ cat some.json | j '[_].map(x => x.some_property + '👍')[0]'
$ cat some.json | j '_.map(x => new Date(x.timestamp).toISOString())'
$ cat some.json | j --file preload.js '_.map(x => x.timestamp)'
$ http https://swapi.co/api/people/ | j 'Object.keys(_)'
$ http https://swapi.co/api/people/ | j '_.count'
$ http https://swapi.co/api/people/ | j '_.results.map(x => x.name)'
$ echo 'not json string \n !!' | j '_.split("\n")'
$ http https://swapi.co/api/people/1/ | j -r "props(['name', 'height'])"  
$ http https://swapi.co/api/people/1/ | j -ramda "props(['name', 'height'])"  
$ http https://swapi.co/api/people/1/ | j "props(['name', 'height'])(_)"

Inject script file

IIFE

// cw-oneline.js
(() => {
  const time = time => new Date(time).toISOString().slice(0, -5).replace('T', ' ')
  return _.map(x => `${time(x.timestamp)} ${x.message}`)
})()

cat downloaded-cw-log.json | j -f cw-oneline.js > deptno.latest.json

Hmm ... Is it easy to look upside down?

add _.reverse()

cat downloaded-cw-log.json | j -f cw-oneline.js '_.reverse()' > deptno.latest.json
