You can use the jq command to parse JSON strings in a shell.<\/p>\n

jq is a highly powerful command-line tool used for manipulating JSON data. It supports various operations such as selecting, filtering, transforming, modifying, and formatting JSON data.<\/p>\n

Here are some examples of parsing JSON strings using jq:<\/p>\n

    \n
  1. Install the jq command (if not already installed):<\/li>\n
  2. # On Ubuntu, run the command “sudo apt-get install jq”
    \n# On CentOS, run the command “sudo yum install jq”<\/li>\n
  3. Parse JSON string.<\/li>\n
  4. Use jq to parse the JSON string located in a file named data.json containing the following data:
    \n{
    \n “name”: “John”,
    \n “age”: 30,
    \n “city”: “New York”
    \n}<\/li>\n
  5. Output results:<\/li>\n
  6. {
    \n “name”: “John”,
    \n “age”: 30,
    \n “location”: “New York”
    \n}<\/li>\n
  7. Choose specific attributes:<\/li>\n
  8. Selecting specific attribute using jq:
    \njq ‘.name’ data.json<\/li>\n
  9. Output:<\/li>\n
  10. The name of the person is John.<\/li>\n
  11. Filtering data:<\/li>\n
  12. Use jq to filter data where the age is greater than 25 in data.json file.<\/li>\n
  13. The output result:<\/li>\n
  14. {
    \n “name”: “John”,
    \n “age”: 30,
    \n “city”: “New York”
    \n}
    \ncan be paraphrased as:
    \n{
    \n “name”: “John”,
    \n “age”: 30,
    \n “residence”: “New York”
    \n}<\/li>\n<\/ol>\n
