The format of man page titles in Unix systems often includes a number in parentheses, which serves a specific purpose in categorizing the documentation.
For example, the title sleep(3) indicates that the sleep command is found in section 3 of the manual, which is dedicated to library functions.
Understanding this numbering system is crucial for developers and system administrators as it enhances the efficiency of navigating and referencing man pages.
