Tool, language and decoders for working with binary data.
fq is inspired by the well known jq tool and language and allows you to work with binary formats the same way you would using jq. In addition it can also present data similar to a hex viewer, transform, slice and concatenate binary data, supports nested formats and has an interactive REPL with auto-completion.
It was originally designed to query, inspect and debug codecs and metadata in media files and containers like mp4, flac, mp3, jpeg. But has since been extended to support a variety of formats like executables, packet captures including TCP reassembly and serialization formats like ASN1 BER, Avro, CBOR, protobuf and a lot more.
In summary it aims to be something like jq, hexdump, dd and gdb combined into one.
NOTE: fq is still early in development so things might change, be broken or do not make sense. That also means that there is a great opportunity to help out!
The "f" in fq originate from file(1) and format in FFmpeg terminology. I pronounce jq /‘dʒei’kju:/ so I usually pronounce fq /‘ef’kju:/.

Basic usage is fq . file.
For details see usage.md
Use one of the methods listed below or download release for your platform. Unarchive it and move the executable to PATH etc.
On macOS if you don't install using a method below you might have to manually allow the binary to run. This can be done by trying to run the binary, ignore the warning and then go into security preference and allow it. Or you can run this command:
xattr -d com.apple.quarantine fq && spctl --add fq
# install latest release
brew install wader/tap/fq
On macOS, fq can also be installed via MacPorts. More details here.
sudo port install fq
fq can be installed via scoop.
scoop install fq
fq can be installed from the community repository using pacman:
pacman -S fq
You can also build and install the development (VCS) package using an AUR helper:
paru -S fq-git
nix-shell -p fq
Use the fq port.
Currently in edge testing but should work fine in stable also.
apk add -X http://dl-cdn.alpinelinux.org/alpine/edge/testing fq
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 run and run tests from source directory:
# run all tests and build binary
make test fq
# it's also possible to use go run
go run fq.go
See TODO.md
See dev.md
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.
