fq
Tool, language and decoders for working with binary data.
In most cases fq works the same way as jq but instead of reading JSON it reads binary data. The result is a JSON compatible structure where values have a bit range, can have symbolic values and know how to be presented in a useful ways.
It was initially developed to debug, inspect and query media files but has since been extended to handle a variety of binary formats.
You can pronounce the name as you wish, I pronounce jq /‘dʒei’kju:/ so I usually pronounce fq /‘ef’kju:/.
NOTE: fq is still early in development so some things are broken or do not make sense. That also means that there is a great opportunity to help out!
Goals
- Make binary formats accessible and queryable.
- Nested formats and bit-oriented decoding.
- Quick and comfortable CLI tool.
- Bits and bytes transformations.
Hopes
- Make it useful enough that people want to help improve it.
- Inspire people to create similar tools.
Usage
Basic usage is fq . file
.
For more details see usage.md
Install
Download release for your

Alpine
Currently in edge testing but should work fine in stable also.
apk add -X http://dl-cdn.alpinelinux.org/alpine/edge/testing fq
Build from source
Make sure you have go 1.17 or later installed.
To install directly from git repository do:
# build and install latest release
go install github.com/wader/fq@latest
# or build and install latest master
go install github.com/wader/fq@master
# copy binary to $PATH if needed
cp "$(go env GOPATH)/bin/fq" /usr/local/bin
To build and run tests from source directory:
make test fq
# copy binary to $PATH if needed
cp fq /usr/local/bin
# it's also possible to use go run
go run fq.go

This project would not have been possible without itchyny's jq implementation gojq. I also want to thank HexFiend for inspiration and ideas and stedolan for inventing the jq language.
