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. This gives you a summary of commands of requested section. Last but not least: information delivered in man pages is not redundant, so read carefully from beginning to end for increasing your chances to find what you need.
Then keep pressing n to get to the next item. In addition, don't be intimidated by the info pages. I know plenty of people who don't use the info pages because of the built-in navigation system.
My favorite solution is to pipe the info pages through less :. This way, I can navigate the info pages using my favorite pager. The info pages will now behave the same as man pages. The apropos utility is seriously handy for finding the appropriate manpage. The default pager for reading a man page is less.
There is documentation on less here. The commands shown under this section in info page are selectable by placing the cursor on the desired command and then pressing enter key. Frequently I find other useful commands or functions that way. I suppose, using most pager is a good idea. This pager is very powerful, but the main feature for me - displaying colored man-pages. This feature improves perception of plain text and eases searching of needed information.
Don't ignore the info pages. Many GNU tools have far more extensive info pages than man pages. Also, if you are an emacs user, don't forget you can read info and manual pages without leaving your editor: M-x info and M-x woman. In Linux man , you can do man -K string note the uppercase K to do a brute force search of a given term. From Kristof answer, if you i.

In case of the former, a lowercase n will scroll through matches forward, a capital N will go backward. The opposite is true for the latter-the question mark. Slightly more complex searches through regular expressions. The difference between man or less and VIM is that you have to use the escape character to declare metacharacters in your expression when using the latter. The good news is that when you are using the former man or less -not so much.
If your are unfamiliar with regular expressions, this means "Search for instances of words iptables OR rules ". After entering this and keeping on pressing n you will be scrolling through the alternating results of the search with the results being nicely highlighted for you with different colors two, actually. If your are trying to skim through the page and want to concentrate on specific terms or concepts-you won't miss a single thing!
In man you can use all the keys mentioned below without using Ctrl. That's for vi only. However, if you want to stay "" and "never leave the home row" like I do lol -it's the way to go. What I'm trying to say is that UNIX has two main flavors of keyboard program controls, which are both parts of the readline library: vi and emacs. Up your chops in either one but, preferably-in both and it'll make your life a lot less complicated.
BASH uses emacs controls by default, but it can easily be set to "vi mode" by typing in set -o vi. The same can be said for regular expressions, but that's going to be way off-topic. I'd even go as far as to say that both of these are the "lingua franca" of UNIX. Now vimman is an excellent manpage viewer, and :Man from within Vim or simply hitting K over a keyword is an excellent manpage browser. Most of us set the PATH variable.
This will show you how to automatically make the man search path match your command search PATH. To resolve this, I use the manpath command to automatically set the man page search path. This works for me on a hundred different systems running everything from FreeBSD 4. If you are annoyed that man printf gives you printf 1 and all you want is printf 3 , you can tell man you want the printf from section 3 by putting the section before printf, like so: man 3 printf , without having 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.
I just use grep. If i were to wonder what the -s option of the read command did, i'd try these commands in order until i got an answer:. In this case only the info command provided a clear answer. This excellent answer gives the details on the different help systems. If you find it hard to read the manpages because of all white colored text, you can colorize them.
Most man pages open with less. For less , I use the following color settings in. This is for bash and zsh. For most , fish , xterm and rxvt see the link above. Colors in Man Pages. The apropos 1 command is used for searching man pages. However, most implementations of apropos 1 just search in the NAME section, which is very limiting.
NetBSD has a full text search implementation of apropos 1 , which is capable of searching the complete content of man pages. There is also a web based interface for it: man-k.

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.

This is due in part to a complex syntax perhaps the most complex of all the standard Unix commands that aren't actually programming languages like awk ; and in part to poorly written man pages. The GNU version's man page didn't even have examples until late ! The very first thing you should do before you proceed any further is actually read your system's man page for the find command. You don't have to memorize it, or understand every part, but you should at least have looked at all the different parts of it once, so you have a general idea what's going on. Then, you might want to look at the OpenBSD man page for comparison. Sometimes, you'll understand one man page more than another.

This file documents the GNU utilities for finding files that match certain criteria and performing various operations on them. This file documents the GNU utilities for finding files that match certain criteria and performing various actions on them. This manual shows how to find files that meet criteria you specify, and how to perform various actions on the files that you find. The principal programs that you use to perform these tasks are find , locate , and xargs. Some of the examples in this manual use capabilities specific to the GNU versions of those programs.
