bash2js

bash2js converts bash output to JavaScript Arrays/Objects and lets you use JavaScript functions on it

Installation

# required NodeJS to work https://nodejs.org/
npm install -g bash2js

How to use

command | bash2js # converts output from "command" to an array/object and prints it
command | bash2js "map(col => col[0])" # converts output from "command", loops through it and prints column of index 0 from each line (expects output to be an array)
command | bash2js test # converts output from "command", prints property with key "test" (expects output to be an object)
command | bash2js "[0]" # converts output from "command", prints first index in the array (expects output to be an array)
command | bash2js > test.json # converts output from "command", saved output to "test.json"

ls -l # outputs
