SYNOPSIS

ascii

DESCRIPTION

The ascii command is a simple utility for displaying an ASCII character chart in the terminal. It provides a quick reference for ASCII values, including decimal, hexadecimal, and octal representations. It also shows the corresponding character representation where applicable. The command is useful for programmers, system administrators, and anyone who needs to quickly look up ASCII values or characters. It can also be useful for understanding the mapping between characters and their numerical representation in computer systems, which is fundamental to many programming tasks such as character encoding and data interpretation. The output is typically formatted as a table, making it easy to read and understand.
While ascii is straightforward to use, the displayed output may vary slightly based on terminal settings and character encoding.

CAVEATS

The displayed output might vary slightly based on the user's terminal settings and character encoding.

OUTPUT FORMATTING

The output of the ascii command usually displays the decimal, hexadecimal and octal values along with the ASCII characters in a table format.

USE CASES

This tool is extremely useful for quick lookups of character mappings, especially in situations where encoding or character conversion becomes a concern.

HISTORY

The ascii command has been a part of Unix-like systems for a long time. It's a simple tool that provides quick ASCII reference. Its simplicity and ease of use contributed to its longevity.
