Accessing man pages on Ubuntu 16.04 LTS

A man page short for manual page is a form of software documentation usually found on a Unix or Unix-like operating system. Topics covered include computer programs including library and system calls , formal standards and conventions, and even abstract concepts. A user may invoke a man page by issuing the man command. By default, man typically uses a terminal pager program such as more or less to display its output. Because man pages are distributed together with the software they document, they are a more favourable means of documenting software compared to out-of-band documentation like web pages , as there is a higher likelihood for a match between the actual features of the software to the documented ones.

Command line users are undoubtedly familiar with man pages, or manual pages, that contain details, help , and documentation to specified commands and functions. Referencing a man page can be essential when trying to learn proper syntax or how a command works, but with how large some manual pages are it can be a real drag to scroll through the entire man page to try and find a relevant portion.

The command used to display them is man. In spite of their scope, man pages are designed to be self-contained documents, consequentially limiting themselves to referring to other man pages when discussing related subjects. This is in sharp contrast with the hyperlink-aware Info documents , GNU's attempt at replacing the traditional man page format. Manuals are sorted into several sections.

How to Search Man Pages at the Command Line

GNU find searches the directory tree rooted at each given starting-point by evaluating the given expression from left to right, according to the rules of precedence see section OPERATORS , until the outcome is known the left hand side is false for and operations, true for or , at which point find moves on to the next file name. If you are using find in an environment where security is important for example if you are using it to search directories that are writable by other users , you should read the "Security Considerations" chapter of the findutils documentation, which is called Finding Files and comes with findutils. That document also includes a lot more detail and discussion than this manual page, so you may find it a more useful source of information. That argument and any following arguments are taken to be the expression describing what is to be searched for. If no paths are given, the current directory is used. If no expression is given, the expression -print is used but you should probably consider using -print0 instead, anyway. These options control the behaviour of find but are specified immediately after the last path name. This is the default behaviour. When find examines or prints information a file, and the file is a symbolic link, the information used shall be taken from the properties of the symbolic link itself.
