Jsawk is a command-line tool that works like awk but for JSON, filtering and transforming arrays of JSON objects read from stdin using JavaScript snippets. It is a shell script that relies on the SpiderMonkey js interpreter and can pipe results to other processes or load JavaScript libraries.

Use cases

• filter JSON arrays from a REST API in a shell script
• transform JSON data into other text formats on the command line
• modify fields of JSON objects fetched via curl or resty before PUT requests
• query and extract values from JSON in bash pipelines
• preprocess or postprocess JSON arrays with custom JavaScript snippets

When to choose

• you need awk-style JSON filtering in shell scripts
• you want a lightweight single-script tool with no heavy dependencies beyond a js interpreter
• you pipe JSON between REST endpoints and other command-line tools

When to avoid

• you need actively maintained software with recent updates or a license
• you prefer modern tools like jq with richer query syntax
• you work in environments where installing SpiderMonkey is impractical
