How do I compare two binary files?

If you want to compare two files byte by byte, you can use the cmp program with the –verbose ( -l ) option to show the values of each differing byte in the two files. With GNU cmp , you can also use the -b or –print-bytes option to show the ASCII representation of those bytes. See Invoking cmp , for more information.

While text files contain only textual data, binary files may contain both textual and custom binary data. Binary files typically contain a sequence of bytes, or ordered groupings of eight bits. When creating a custom file format for a program, a developer arranges these bytes into a format that stores the necessary information for the application.

How can I check if two binary files are the same?

There is a relatively simple way to check if two binary files are the same. If you use file input/output in a programming language; you can store each bit of both the binary files into their own arrays. Thanks for contributing an answer to Stack Overflow!
