|Simplified Manual Pages
The standard set of manual pages (often called man pages) which are available in most flavours of Linux, BSD and Unix tend to be long and they can be cryptic. Manual pages tend to list what options are available without explaining why we might use them. Further, many manual pages do not provide examples.
The TLDR-pages project has compiled a collection of simplified manual pages which present commands with a clear explanation of what each command does and lists examples of how the command is most often used. These simplified pages are available below.
