Find in man pages

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.

New sentences should be started on new lines. This makes it easier to see the effect of patches, which often operate at the level of individual sentences. For those few man-pages pages in Sections 1 and 8, probably you just want to write GNU. For system calls, just write Linux. However, this was never done consistently, and so was probably worse than including no version number.

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frequently hard to read, as they try to be authoritative and are therefore often too technical for new users frequently out of date That said, they're still better and more comprehensive than the alternatives.

Pay attention to the section number: Suppose you want help on printf. The bash version of printf is in section 1, the C version is in section 3 or 3C. If you don't know which one you want, type man -a printf , and all manual pages will be displayed. You may find something like formats 5 , which suggests you to type man 5 formats. If you are annoyed that man printf gives you printf 1 and all you want is printf 3 , you have to change the order of scanned directories in the MANPATH environment variable and put the ones for C language before the ones for shell commands.

How to Search Man Pages at the Command Line

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.

How to use a man page: Faster than a Google search

Command line users are undoubtedly familiar with man pages, or manual pages, that contain details, help , and documentation to specified commands and functions. Referencing a man page can be essential when trying to learn proper syntax or how a command works, but with how large some manual pages are it can be a real drag to scroll through the entire man page to try and find a relevant portion. Note the flag is a capital -K, the string can be anything. Any matches to the syntax in the current man page will be highlighted.

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.
