I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look at it.

The Linux common command hexdump command is generally used to view the hexadecimal encoding of "binary" files, but in fact it can view any file, not just binary files.

Hexdump display file hexadecimal format

Syntax hexdump [options] [file]... Option-n length formats only the first length bytes of the input file. -C outputs hexadecimal and ASCII codes of the specification. -b single-byte octal display. -c single byte character display. -d double-byte decimal display. -o double-byte octal display. -x double byte hexadecimal display. -s outputs from the offset. -e specifies the format string, which is contained in a pair of single quotation marks, such as:'a format1 b', "format2"'. Each format string consists of three parts, each separated by spaces, the first shape, such as a _ 4. Format strings similar to printf can be used in format1 and format2, such as:

D: two-digit decimal x: three-digit hexadecimal o: two-digit octal% c: single character, etc. There are also some special uses:

% _ ad: marks the sequence number of the next output byte, expressed in decimal. % _ ax: marks the sequence number of the next output byte, expressed in hexadecimal. % _ ao: marks the sequence number of the next output byte, expressed in octal. % _ p: for those that cannot be displayed in regular characters. Instead. If you want to display multiple format strings on the same line, you can follow multiple-e options.
