The command "ascii -d" is used to display the decimal ASCII values of characters. ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns unique numeric codes to represent characters in computers and communication systems.
When you execute the "ascii -d" command, it will list the decimal values of ASCII characters. For example, it may display something like:
Dec Char
65 A 66 B 67 C ... 97 a 98 b 99 c ...
It sequentially lists the decimal values for both uppercase and lowercase letters, numerals, punctuation marks, and other ASCII characters. This can be useful to identify the corresponding decimal value of a character, or to understand the character set being used by a system or program.
