hexdump

An ASCII, decimal, hexadecimal, octal dump. More information: https://manned.org/hexdump.

• Print the hexadecimal representation of a file, replacing duplicate lines by '*':

hexdump {{path/to/file}}

• Display the input offset in hexadecimal and its ASCII representation in two columns:

hexdump {{[-C|--canonical]}} {{path/to/file}}

• Display the hexadecimal representation of a file, but interpret only n bytes of the input:

hexdump {{[-C|--canonical]}} {{[-n|--length]}} {{number_of_bytes}} {{path/to/file}}

• Don't replace duplicate lines with '*':

hexdump {{[-v|--no-squeezing]}} {{path/to/file}}
