How do you reverse a hex dump?
You can use xxd to dump binary files just like hexdump and od, but you can also use it to do the reverse: turn a hex dump back into binary. If you run xxd with just a file name it dumps the data in a fairly standard hex dump format: # xxd bdata 0000000: 0001 0203 0405 ……
What can you do with a hex dump?
Hexdump is a utility that displays the contents of binary files in hexadecimal, decimal, octal, or ASCII. It’s a utility for inspection and can be used for data recovery, reverse engineering, and programming.
What is xxd command?
DESCRIPTION. xxd creates a hex dump of a given file or standard input. It can also convert a hex dump back to its original binary form. Like uuencode(1) and uudecode(1) it allows the transmission of binary data in a ‘mail-safe’ ASCII representation, but has the advantage of decoding to standard output.

When to add a trailing null byte to hexdump?
The sed part converts hexdump ‘s format into xxd ‘s format, at least so far that xxd -r works. A trailing null byte is added if the original file was of odd length (e.g. 1, 3, 5, 7., byte long). Repeating sections of the original file are not restored correctly if they were hexdump ed using a *.
