hexdump

The blog explains the use of `xxd -r -p` in Linux to convert hexdumps back to binary, primarily focusing on formats without line breaks. A hexdump, frequently used in debugging, displays binary data in hexadecimal format. The `xxd` utility facilitates reversing hexdumps to binary, with `-r` for reversing and `-p` to output without whitespace, helping in data forensics or software development. The guide also includes script examples, installation, and execution steps for practical application.
