Dear core os maintainers community!
Now I'm working a lot with binary data (gRPC traffic), and I found `tail
-c` / `head -c` / `hexdump -C` extremely useful. The only thing is that I
have to count offsets (limits) for tail/head manually each time relying on
hexdump's markers which are in hex numbers. It would be nice to support
something like, for instance, `tail -c +0x1a my_binary_dump.bin`. I even
could try to implement this feature myself, but first I want to get
approvals and advice from the community.
Similar suggestions have been made for other numeric inputs,
but the general advice is to use the standard shell syntax
to do the conversion, which is more generally applicable.
For example in this case it would be:
tail -c +$((0x1a)) my_binary_dump.bin
cheers,
