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.

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. The above command helps you with the complete information about the pwd command.

Try it yourself at your command prompt to get more detail. Man pages are generally divided into sections, which generally vary by the man page author's preference. Lists other commands that are directly related to the command in the man page or closely resemble its functionality.

To sum it up, man pages are a vital resource and the first avenue of research when you need information about commands or files in a Unix system. The following link gives you a list of the most important and very frequently used Unix Shell commands.

If you do not know how to use any command, then use man page to get complete detail about the command. Previous Page. Next Page. Previous Page Print Page. BUGS Explains any known issues or bugs that exist with the command or its output.

Master the command line: How to use man pages

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:.

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 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.

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. This means that the MKDIR command is documented under that name, in section 1 given within parentheses.

man command in Linux with Examples

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?

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.

Unix / Linux - Shell Manpage Help

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.

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.

Still, they are critical. Commands can vary slightly on different Unix systems, and the manual pages are the most reliable way to find out what your system does.
