fq - Tool, language and decoders for working with binary data

[Zeokat]

Personally i find this tool very handly and maybe is usefull for you too.

fq is inspired by the well known jq tool and language that allows you to work with binary formats the same way you would using jq. In addition it can present data like a hex viewer, transform, slice and concatenate binary data. It also supports nested formats and has an interactive REPL with auto-completion.

It was originally designed to query, inspect and debug media codecs and containers like mp4, flac, mp3, jpeg. But since then it has been extended to support a variety of formats like executables, packet captures (with TCP reassembly) and serialization formats like JSON, YAML, XML, ASN1 BER, Avro, CBOR, protobuf. In addition it also has functions to work with URLs, convert to/from hex, number bases, search for things etc.

In summary it aims to be jq, hexdump, dd and gdb for files 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!
