Unix get man pages

Site Logo

The most empowering information you can get is how to conduct your own research. Following this precept, we'll now tell you about the online help system that comes built in to Unix systems. It is called manual pages, or man pages for short. Actually, manual pages are not quite the boon they ought to be. This is because they are short and take a lot of Unix background for granted.

I got the "Unix And Linux System Administration Handbook" It speaks of several verisons of linux and unix, and the commands for viewing linux man pages and not specific to ubuntu.

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.

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.

The usual way to access to man pages is via the man command. For example, try:. You will see one screen of the manual followed by a Manual page prompt at the bottom of your terminal screen. You can type the characters h or? Typing q will return you from the help screen back to the manual page itself.

man command in Linux with Examples

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. Then, if you type man pwd , for example, Terminal will display the man page for the pwd command. All man pages have a common format. They begin with name the name of the command and a brief description of what it does.

Unix / Linux - Shell Manpage Help

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.

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.

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.

Use the Unix man command to read manual pages

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. We'll try to address the first three failings in this document. Man pages are the standard documentation for every Unix; you're sure to come across a reference before too long of the form:. Where N is a number from , possibly followed by a letter. Here's an example we'll pick apart note: this example does not apply to all UNIX's but should be taken as general form.

Mar 30, - man pages—abbreviation for "manual pages"—are the form of that is available on almost all UNIX-like operating systems, including Arch Linux. If you are getting a "nothing appropriate" message for every search.

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.
