A man page , acronym of man ual page , is a software documentation found in all Unix-like operating systems. Some man pages are short; some are comprehensive. A man page is divided into several parts, organized with headings for each section, such as NAME, SYNOPSIS, CONFIGURATION, DESCRIPTION, OPTIONS, EXIT STATUS, RETURN VALUE, ERRORS, ENVIRONMENT, FILES, VERSIONS, CONFORMING TO, NOTES, BUGS, EXAMPLE, AUTHORS, and SEE ALSO.
Sometimes, I find it really time-consuming when I wanted to learn a practical example of a given Unix command using man pages .

Thankfully, there are some really good alternatives out there. In this tutorial, we will be discussing 5 alternatives to man pages for Unix-like operating systems.
