Short satire about a comically upscaled spaceship. It displays the hex (and 7-bit ASCII) of the two files one above the other, with any differences highlighted. While less Other common options are -tx2, which outputs two bytes per block in hexadecimal format and reverts the byte order in each block, and -to1, which outputs one byte per block in octal format.

We could replace diff with vimdiff to navigate the file for easier comparison (in this and all previous solutions): In this last solution, we first compare the two binary files byte by byte with the cmp tool: As we were expecting, there are three locations where the two files differ. However, by inspection, we can check that the order in the block of two bytes has been inverted: With hexdump, we have 2e-41, while with xxd, we have 41-2e. Generate a test case with a single removal of byte 64: If you also want to see the ASCII version of the character: When using hexdumps and text diff to compare binary files, especially xxd, the additions and removals of bytes become shifts in addressing which might make it difficult to see.
