The rule “nolonglines” provides a warning if the source line is longer than 80 characters. You may wish to customize the ‘80’ for your environment and editing tools.
It is sometimes difficult to understand programs with lines longer than your editor can support. Many unix editors are set to the emulator’s width, and typically that is 80.
How to solve this:
Reformat your code to <80 characters.
How to suppress these warnings:
Disable the rule or change the width.
