hexdump: file viewer in ASCII, decimal, octal, or hexadecimal
hexdump is part of util-linux [1], simple and easy to use in terminal. `-C` probably is the common use, providing hex and ASCII views.
Not only it can display in ASCII and three different number bases, it can also display by 2-byte rather than just 1-byte.
Also, it has a fairly flexible formatting, `-e` and `-f`. If only a small portion is needed, then `-s` offset and `-n` length would be helpful to display the only part you need.
Recorded with hexdump from util-linux 2.22.2
