Ask HN: Unix-like tools for reverse engineering

Hi, HN! Do you know of any toolkit for reverse engineering based on the Unix philosophy (i.e., specific tools for specific tasks, instead of a large application)?

While Ghidra and IDA Pro are great, a set of CLI tools for analyzing the shape of the call graph, finding program patterns (e.g., a sequence of instructions that could be a hash function), etc. might be useful, in case there isn't a toolkit yet.

If such a toolkit doesn't exist, is it an actual need in the professional reverse engineering community, or just a nice-to-have?
