Get man pages

Jump to navigation. It's easy to get into the habit of googling anything you want to know about a command or operation in Linux, but I'd argue there's something even better: a living and breathing, complete reference, the man pages , which is short for manual pages. The history of man pages predates Linux, all the way back to the early days of Unix. Man pages also have a reputation of being terse and, in a way, have a language of their own. Just like Unix and Linux, the man pages have not been static, and they continue to be developed and maintained just like the kernel. Even so, users generally don't need to know the section where a particular command lies to find what they need.

Getting Help and Using the Unix Manual

The Linux command line offers a wealth of power and opportunity. If your memory is like mine then you find it hard to remember a large number of details.

Fortunately for us there is an easy to use resource that can inform us about all the great things we can do on the command line. That's what we're going to learn about in this section. I know you're keen and eager to get stuck into doing stuff, and we'll get started on that in the next section, I promise, first we need to learn how to use Manual pages however. The manual pages are a set of pages that explain every command available on your system including what they do, the specifics of how you run them and what command line arguments they accept.

Some of them are a little hard to get your head around but they are fairly consistent in their structure so once you get the hang of it it's not too bad. You invoke the manual pages with the following command:. It is possible to do a keyword search on the Manual pages. This can be helpful if you're not quite sure of what command you may want to use but you know what you want to achieve.

To be effective with this approach, you may need a few goes. It is not uncommon to find that a particular word exists in many manual pages. If you want to search within a manual page this is also possible.

A lot of being proficient at Linux is knowing which command line options we should use to modify the behaviour of our commands to suit our needs. A lot of these have both a long hand and short hand version.

Above you will notice that to list all directory entries including hidden files we can use the option -a or --all remember from last section what files and directories beginning with a. The long hand is really just a more human readable form.

You may use either, they both do the same thing. One advantage of using long hand is that it can be easier for you to remember what your commands are doing. One advantage of using shorthand is that you can chain multiple together easier. As you can see, long hand command line options begin with two dashes -- and short hand options begin with a single dash -.

When we use a single dash we may invoke several options by placing all the letters representing those options together after the dash. There are a few instance where a particular option requires an argument to go with it and those options generally have to be placed separately along with their corresponding argument. Don't worry too much about these special cases for now though. We'll point them out as we encounter them.

How to use a man page: Faster than a Google search

There are four ways to get help when using Unix: from external documentation such as this book, Web sites, and other similar materials; from the extensive Unix reference manuals that come with every version of Unix, including Mac OS X; from the built-in help that comes with most commands; and from other people via online discussion systems, e-mail, user groups, and, yes, calling your friends on the telephone. You are already taking the first approach, so this chapter concentrates on the other three. The Unix reference manual is a collection of files called man pages, which are specially formatted files intended to be viewed with the man command. Unix man pages are written for an audience of experienced programmers, not for novice users, so to understand Unix man pages, you need to understand the conventions used in them. Mac OS X comes with almost Unix man pages. Some of these pages come from Apple itself, and some come from the software that Apple acquired when it bought NeXT. As of this writing summer , Apple has made progress updating the man pages to be Darwin specific, but the job is not yet done. Fortunately, most of the man pages do not require updating; unfortunately, there is no easy way to know which ones do require it. Command-line programs almost always provide a minimal level of built-in help—usually just enough to show you the options and arguments the command expects. Still, that is often enough to remind you of the proper way to use the command.

I know you can just use help or man bash and search to find info about it, but I want them separated, so I can just do man read and get the read manpage. You may have to hit n a couple of times to get to the actual command instead of a paragraph that happens to have the command name as the first word.

Oooh, I just know I'm going to hear it in the comments for that one. But you know what?

While they're not all well-advertised, there are actually a variety of means of getting help under Unix. Man pages correspond to online manuals for programs, file formats, functions, system calls, and so forth. If you've never read one before, the best way to start is by typing 'man man ' at the command line. Of course, while man pages are a vast improvement over the online documentation of most other OSes, they suffer from many failings: some people don't like to read text on the screen not very helpful unless you already know what to look for not always accessible even when present not always present, especially under Linux frequently hard to read, as they try to be authoritative and are therefore often too technical for new users frequently out of date That said, they're still better and more comprehensive than the alternatives.

Linux man Command Tutorial for Beginners (8 Examples)

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 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. For a full listing see the section entitled "Sections of the manual pages" in man-pages 7.

man command in Linux with Examples

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.

This manual page documents the GNU version of find. GNU find searches the directory tree rooted at each given starting-point by evaluating the given expression.

Is it some kind of arcane knowledge, handed down only to initiates after grueling initiations? Well, no. Actually, anyone can learn about Terminal commands, if they know where to look. The key to Terminal wisdom is the man command.

Master the command line: How to use man pages

Section-num : Since a manual is divided into multiple sections so this option is used to display only a specific section of a manual. So this option gives the section in which the given command is present. In this example you can move through the manual pages sections i.

The manual covers various methods to use device, safety procedures and troubleshooting tips. When it comes to computers you rarely, if ever, get a physical manual.
