jq

jq is a lightweight and flexible command-line JSON processor akin to sed,awk,grep, and friends for JSON data. It's written in portable C and has zero runtime dependencies, allowing you to easily slice, filter, map, and transform structured data.

Installation

Prebuilt Binaries

Download the latest releases from the GitHub release page.

Docker Image

Pull the jq image to start quickly with Docker.

#### Run with Docker

##### Example: Extracting the version from a package.json file

bash
docker run --rm -i ghcr.io/jqlang/jq:latest < package.json '.version'

##### Example: Extracting the version from a package.json file with a mounted volume

bash
docker run --rm -i -v "$PWD:$PWD" -w "$PWD" ghcr.io/jqlang/jq:latest '.version' package.json

Building from source

#### Dependencies

- libtool
- make
- automake
- autoconf

#### Instructions

console
git submodule update --init    # if building from git to get oniguruma
autoreconf -i                  # if building from git
./configure --with-oniguruma=builtin
make clean                     # if upgrading from a version previously built from source
make -j8
make check
sudo make install

Build a statically linked version:

console
make LDFLAGS=-all-static

If you're not using the latest git version but instead building a released tarball (available on the release page), skip the autoreconf step, and flex or bison won't be needed.
