JQ to filter JSON by value

The article explains how to use the `jq` command-line tool to filter JSON data by a specific value. It provides the syntax `cat <filename> | jq -c '.[] | select( .<key> | contains("<value>"))'` and notes that numeric values should not be enclosed in quotes within the `contains()` function. An example filters for records where the `_id` key equals the numeric value 611.

Syntax: cat <filename | jq -c '. | select .<key | contains "<value " ' Example: To get json record having id equal 611 cat my.json | jq -c '. | select . id | contains 611 ' Remember: if JSON value has no double quotes eg. for numeric to do not supply in filter i.e. in contains 611
