You can also view man pages in a browser. Your knee-jerk reaction when trying to study about new command or config file should be:. The argument to man is actually manpage name and the package maintainer is expected to add any manpages users would need. For many prolific packages, you can normally expect:. However the man page system is a huge, really rich resource. There are actually far more man pages that don't deal with particular command or even particular program.
For example, the manpage system typically contains documentation of:. Also, packages may provide their documentation as manpage sections. For example, perl-doc adds section 3perl where you can find all its modules, OpenSSL adds 3ssl. Not sure if it's on Ububtu, but on Fedora there is man-pages package that provides even more goods like POSIX versions of commands or system calls.

Also, some tools have more extensive manuals in info pages so info grep ; and some commands that are an internal part of the bash shell rather than being separate external files are documented on help pages for example: help echo.
And, of course, many programs have a --help option that displays the most common usages. And note that the argument doesn't have to be a package name. It can be a command, a file, a function name, Sorry, but this is IMO too inacurrate. The man argument is manpage name, not package name. The convention followed by most, but not all packages is to add a manpage per command, which is why man grep works, but there are manpages that don't describe commands.
Jobin answer is perfect, I always like to add more options so Op can know it. Braiam Hedwig Hedwig 5 5 bronze badges.
Parto Parto Your knee-jerk reaction when trying to study about new command or config file should be: man command man file. For many prolific packages, you can normally expect: one manpage per command -- named exactly as the command, at least one manpage about configuration files typically named exactly as the main configuration file.
For example, the manpage system typically contains documentation of: commands section 1 but often also pages that are not directly commands eg.

How to effectively use Man Pages under Linux
Click here to browse the author's latest version of this document. Corrections and suggestions welcome! This HOWTO explains what you should bear in mind when you are going to write on-line documentation -- a so-called man page -- that you want to make accessible via the man 1 command. Throughout this HOWTO, a manual entry is simply referred to as a man page, regardless of actual length and without sexist intention.
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.
How to Search Man Pages at the Command Line
In Unix , most programs, and many protocols, functions, and file formats, have accompanying manuals. With the man command, you can retrieve the information in the manual and display it as text output on your screen. To use the man command, at the Unix prompt, enter:. Replace topic with the name of the manual item about which you want more information. For example, to find out more about the FTP command, at the Unix prompt, enter:. If you are unsure which manual item you want to read, you can do a keyword search. At the Unix prompt, enter:. On some systems, you need to replace man -k with apropos. For example, at the Unix prompt, enter:. In both of the examples above, replace keyword with a specific topic for example, ftp , mail.

All the Unix commands come with a number of optional and mandatory options. It is very common to forget the complete syntax of these commands. Because no one can possibly remember every Unix command and all its options, we have online help available to mitigate this right from when Unix was at its development stage. Unix's version of Help files are called man pages. If there is a command name and you are not sure how to use it, then Man Pages help you out with every step.
Man pages are generally written by the developer of the corresponding program. Generally the man pages are divided into number of sections. The following is the list of all available man sections. Every section has a unique number and contains only a specific type of man pages.

On Linux and other Unix -like operating systems , man is the interface used to view the system's reference manuals. Each argument given to man is normally the name of a program , utility or function. The manual page associated with each of these arguments is then found and displayed. A section number, if provided, will direct man to look only in that section of the manual. The default action is to search in all of the available sections, following a pre-defined order and to show only the first page found, even if page exists in several sections. When viewing a pure ASCII manual page on a 7-bit terminal or terminal emulator , some characters may not display correctly when using the latin1 device description with GNU nroff.

Text shown in brackets is optional.
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.
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
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. In fact, man itself is a command, whose role is to format and display this documentation.
