Linux man Command Tutorial for Beginners (8 Examples)

Site Logo

A very useful aspect of the Linux command line is that the documentation for almost all command line tools is easily accessible. These documents are known as man pages, and you can easily access them through the command line using the man command.

In this tutorial, we will discuss the basics of man using some easy to understand examples. But before we do that, it's worth mentioning that all examples in this article have been tested on Ubuntu The man command gives users access to manual pages for command line utilities and tools.

Following is the syntax of this command:. The basic usage of man is very simple - just run the command with the name of the tool whose reference manual you want to access. As already mentioned in the beginning, all available manual pages are segregated into sections, and there are sections that contain man page entries of same name. Well, you don't have to do that as there exists a command line option 'f' that allows man to display all manual pages that match the name in the input.

So you can see all entries with name 'printf' - along with section numbers - were displayed in the output. Now, what if you want man to display one by one all manual pages corresponding to a given input? Well, that's possible, and you'll have to use the -a command line option for it. For example, if you want to serially view all man pages for 'printf', you can do that in the following way:.

The above command will first open the printf man page from section 1, and when you quit it, the command will ask you if you want to view the next 'printf' man page.

In case you want the man command to search and list manual pages by considering input as a regular expression, you can do that using the -k command line option. In case the requirement is to only know the location of manual pages, you can force man to do this by using the -w command line option. By default, the man command ignores case while searching for manual pages. However, if you want, you can enable case-sensitivity using the -I command line option.

So you can see man is an extremely important command that users - both newbies and pros - should know how to use. We've just scratched the surface here, as the tool offers a lot of features.

Accessing man pages on Ubuntu 16.04 LTS

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. Note the flag is a capital -K, the string can be anything. Any matches to the syntax in the current man page will be highlighted. And for those who use Terminal app, remember you can also search and launch manual pages from the Terminal Help menu directly, which would then allow you to use the aforementioned string search to look within a help doc to get further details.

A very useful aspect of the Linux command line is that the documentation for almost all command line tools is easily accessible. These documents are known as man pages, and you can easily access them through the command line using the man command.

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

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. In the first two years of the history of Unix , no documentation existed. The first actual man pages were written by Dennis Ritchie and Ken Thompson at the insistence [ citation needed ] of their manager Doug McIlroy in Aside from the man pages, the Programmer's Manual also accumulated a set of short papers, some of them tutorials e.

GUI Methods

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.
