Find man page linux
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.SEE VIDEO BY TOPIC: Linux Man Pages - A Quick Tutorial

Linux find command
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.

Master the command line: How to use man 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.
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.
find(1) [v7 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. For a full listing see the section entitled "Sections of the manual pages" in man-pages 7. Man pages are usually referred to by their name, followed by their section number in parentheses. Often there are multiple man pages of the same name, such as man 1 and man 7. In this case, give man the section number followed by the name of the man page, for example:. Man pages all follow a fairly standard format, which helps in navigating them.

Search a folder hierarchy for filename s that meet a desired criteria: Name, Size, File Type - see examples. GNU find searches the directory tree rooted at each given file name by evaluating the given expression from left to right, according to the rules of precedence see Operators , until the outcome is known the left hand side is false for AND operations, true for OR , at which point find moves on to the next file name. The -H, -L and -P options control the treatment of symbolic links. That argument and any following arguments are taken to be the expression describing what is to be searched for.
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.
man command in Linux with Examples
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.

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. Following is the syntax of this command:.
On Unix-like operating systems, the find command searches for files and directories in a file system. Within each directory tree specified by the given path s, it evaluates the given expression from left to right, according to the rules of precedence see " Operators ", below until the outcome is known. At that point find moves on to the next path until all path s have been searched. It can be used on its own to locate files, or in conjunction with other programs to perform operations on those files. The -H , -L and -P options control the treatment of symbolic links. Arguments following these are taken to be names of files or directories to be examined, up to the first argument that begins with " - ", or the argument " " or "! That argument and any following arguments are taken to be the expression describing what is being searched. If no path s are given, the current directory is used.

Беккер почувствовал, что у него подкашиваются ноги. Этого не может. Росио игриво улыбнулась и кивнула на немца. - El queria que lo guardara. Он хотел его оставить, но я сказала.
