The manual covers various methods to use device, safety procedures and troubleshooting tips. When it comes to computers you rarely, if ever, get a physical manual. Short for manual pages , the man pages are a type of document that provides details on using various commands and applications. Man pages are super simple to use and can help you learn without Google! A man page is a piece of documentation that is distributed and read digitally.SEE VIDEO BY TOPIC: Linux Man Pages Tips and Tricks
How to use a man page: Faster than a Google 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.
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.
In the first two years of the history of Unix , no documentation existed. The first actual man pages were written by Dennis Ritchie and Ken Thompson at the insistence [ citation needed ] of their manager Doug McIlroy in Aside from the man pages, the Programmer's Manual also accumulated a set of short papers, some of them tutorials e.
Later versions of the documentation imitated the first man pages' terseness. For the Fourth Edition the man pages were formatted using the troff typesetting package  and its set of -man macros which were completely revised between the Sixth and Seventh Editions of the Manual ,  but have since not drastically changed. At the time, the availability of online documentation through the manual page system was regarded as a great advance.
To this day, virtually every Unix command line application comes with a man page, and many Unix users perceive a program's lack of man pages as a sign of low quality; indeed, some projects, such as Debian , go out of their way to write man pages for programs lacking one. The modern descendants of 4. There was a hidden easter egg in the man-db version of the man command that would cause the command to return "gimme gimme gimme" when run at a reference to the ABBA song Gimme!
A Man After Midnight. It was introduced in  but first restricted  and then removed in  after finally being found. The default format of the man pages is troff , with either the macro package man appearance oriented or mdoc semantic oriented.
This makes it possible to typeset a man page into PostScript , PDF , and various other formats for viewing or printing. It is meant to only support of a subset of troff used in manual pages, specifically those using the mdoc macros. In February , the BSD community saw a new open source mdoc.
For Linux, a man7. Pages are traditionally referred to using the notation "name section ": for example, ftp 1. The same page name may appear in more than one section of the manual, such as when the names of system calls , user commands , or macro packages coincide. Examples are man 1 and man 7 , or exit 2 and exit 3.
The syntax for accessing the non-default manual section varies between different man implementations. On Solaris and illumos, for example, the syntax for reading printf 3C is:. Unix System V uses a similar numbering scheme, except in a different order: . Some sections are further subdivided by means of a suffix; for example, in some systems, section 3C is for C library calls, 3M is for the math library, and so on. A consequence of this is that section 8 system administration commands is sometimes relegated to the 1M subsection of the main commands section.
Some subsection suffixes have a general meaning across sections:. Some versions of man cache the formatted versions of the last several pages viewed. One form is the cat page , simply piped to the pager for display. All man pages follow a common layout that is optimized for presentation on a simple ASCII text display, possibly without any form of highlighting or font control.
Sections present may include:. Other sections may be present, but these are not well standardized across man pages. Manual pages can be written either in the old man macros, the new doc macros, or a combination of both mandoc. This information can be used to implement a semantic search for manuals by programs such as mandoc.
Although it also includes directives to directly control the styling, it is expected that the specialized macros will cover most of the use-cases. Although man pages are, to troff, text laid out using point Roman type , this distinction is usually moot because man pages are viewed in the terminal TTY instead of laid out on paper. As a result, the "small font" macro is seldom used. The BSD mandoc however only supports bold and underlined text via the typewriter overstrike-with-backspace sequence, which needs to be translated into ECMA by less.
Man pages are usually written in English, but translations into other languages may be available on the system. The GNU man-db and the mandoc man is known to search for localized manual pages under subdirectories.
Few alternatives to man have enjoyed much popularity, with the possible exception of GNU Project's " info " system, an early and simple hypertext system. There is also a third-party effort known as " TLDR pages" that provides simple examples for common use cases, similar to a cheatsheet.

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.
What are man pages?
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:. It is possible to do a keyword search on the Manual pages. This can be helpful if you're not quite sure of what command you may want to use but you know what you want to achieve.

In the absence of an expression, -print is assumed. If an expression is given, but none of the primaries -delete , -exec , -execdir , -ls , -ok , -print , or -print0 are specified, the given expression is effectively replaced by given expression -print. It is not an error to specify more than one of the mutually exclusive options -H and -L. Where more than one of these options is specified, the last option given overrides the others. If terminated by a semicolon, the utility is executed once per path.
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.

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.

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. Why do we write documentation? Silly question.

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.
