# 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.

|
## Documentation
|

|
|
- **Official Documentation**: [jqlang.github.io/jq](https://jqlang.github.io/jq)
|

|
|
|
|
## Installation
|
|
|
|
### Prebuilt Binaries
|
|
|
|
Download the latest releases from the [GitHub release page](https://github.com/jqlang/jq/releases).
|
|
|
|
### Docker Image
|
|
|
|
Pull the [jq image](https://github.com/jqlang/jq/pkgs/container/jq) 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 -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.
