Line 1: {{draft task}} A [~~https~~[wp:~~//en.wikipedia.org/wiki/~~Hex_dump \|hex dump]] is a textual representation of bytes in a file, and ''hexdump'' is a command-line tool that can dump bytes from a file in a variety of formats, including [[wp:Hexadecimal\|hexadecimal]], [[wp:Octal\|octal]] and [[wp:ASCII\|ASCII]]. [https://man.freebsd.org/cgi/man.cgi?query=hexdump hexdump]'s canonical format displays, on each line:▼ ~~''hexdump'' is a command-line tool that can dump bytes from a file in a variety of formats, including hexadecimal, octal and ASCII.~~ ▲hexdump's canonical format displays, on each line: * a byte offset in hexadecimal, * up to 16 bytes in hexadecimal, separated by spaces, with an extra space between the 8th and 9th byte, * the same 16 bytes interpreted as ASCII characters, with non-printing and non-ascii characters replaced with a dot (<code>.</code>), surrounded by pipes (<code>\|</code>). The last line of output shows a final byte count, also in hexadecimal. For example, the string "Rosetta Code is a programming chrestomathy site 😀." encoded in [[wp:UTF-16\|UTF-16]] (little-endian - the first two bytes are the [[wp:Byte_order_mark\|byte order mark]]), displayed in the canonical format is: <pre>
