How to search in man page
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.SEE VIDEO BY TOPIC: Post Malone, Swae Lee - Sunflower (Spider-Man: Into the Spider-Verse)

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frequently hard to read, as they try to be authoritative and are therefore often too technical for new users frequently out of date That said, they're still better and more comprehensive than the alternatives.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. The section may be necessary in case there are multiple man pages for the same name. In the example above there are man pages called 'mkdir' in both sections 1 and 2v. If unspecified, man will give you the first manpage it finds. The -f option will show you all the available man pages for a given name. You should be able to get a description of each section they vary from Unix to Unix by doing.
This discribes the various flags and the proper format the command requires. The flag in this instance is -p and the syntax requires a directory name to follow. This function is also available by running apropos 1 , i. It lets you search the database of man page summaries to look for a keyword that might be mentionned in them.
Suppose we were looking for utilities to manipulate postscript documents. This produces a list, with summaries, of man pages which are likely to be related to your topic. Note, these commands search the database which in most cases must be built by the system administrators, a task which is sometimes forgotten.
If you can't find what you are looking for and you believe it's there, try doing. SunOS has no such option. There can be several hierarchies of man pages, depending on the system. The command whereis may be able to help here.
For example: note: this specific example should not be taken as generic under Unix but only as a illustration of possible results. Alternatively, you can just try the quick-and-dirty method of running grep 1 in the man directories you think might contain the command you are looking for; note that man pages are not stored in plain text format so the output may not be always readable.
Ok, you have tried the suggestions given above to locate man pages, and still have not had any luck. It's quite possible there is no man page corresponding to what you're looking for - either because the tool or functionality you're searching for isn't installed on the system or because it has no man page installed the latter is far more common under Linux than elsewhere.
Let's suppose that you're especially determined because you "know" that the command exists - it does something, just not quite what you want. Rather than get irate at the undocumented command, first make sure that it is actually a program that deserves a man page; here's an algorithmic approach to looking for a command's help file.
If you are given a path, then you may be justified in being irate. Or maybe the documentation is in another format; keep reading. You have a couple of options here, depending on whether you mind wasting a full page of paper for each page of text.
We recommend printing man pages at least half-size, as you're unlikely to return to them a month later. This will produce a file called Manpage. Unfortunately, while the -t parameter is itself portable to virtually all man implementations, the output is not.
Under Linux, the above works fine. If you have trouble getting psnup to work or don't feel like fooling around with it, you can always work with text instead. Personally, I recommend previewing the output with ghostview 1 beforehand. Not all documentation is located in the manpages. The shells sometimes have online help, as do various other programs, especially graphical ones.
Info isn't really complex enough to deserve describing in detail. In brief, you can read info pages within emacs using 'C-h i' 'info' or from the command line using the command. Online help and a tutorial on the info system are available from within both interfaces. Don't discount info pages; although they are used mainly by GNU software, this includes such hugely useful info pages as gdb , gcc , emacs , gawk , and make.
Perl and bash also have info pages, though the information is available by other means as well in their cases. Only available under Linux, and often not terribly interesting, as a well-behaved package will provide documentation that can be integrated with the major help systems. Still, there is a lot there, and should definitely be considered if you cannot find what you are looking for elsewhere.
We will make the assumption that you know how to deal with these formats. Use the information in this document to find help and read up on lynx 1 , ghostview 1 , and less 1. These are more common to the servers, though they may exist on Linux machines as well. Software packages are commonly installed into. Sometimes there is documentation to be found there.
Much Perl documentation is embedded with the source modules themselves. To access it, you can usually do. While it should probably be a last resort, the source IS always the most current and sometimes the only documentation available for a particular package. Whether or not the program you are trying to learn more about is written in a compiled or interpreted language.
find(1) - Linux man page
The online Reference Manual man pages provide detailed descriptions and usage of the commands. You can use the man command to display the man page entry that explains a given command. The syntax of the man command is as follows. The online man page entries are organized into sections based on the type or usage of the command or file.

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:.
Linux Tutorial - 4. Manual Pages
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.
This guide shows how to navigate man pages using the man command. Everyone at some point in their Linux life has used it: the man command. However, while the man program itself appears to be rather simplistic in its construct, it has a few extra abilities than just simply scrolling through the page. This document hopes to help shed some light on these capabilities.

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. The files are formatted in a way that may look odd to many users today.
