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. Then, if you type man pwd , for example, Terminal will display the man page for the pwd command. All man pages have a common format. They begin with name the name of the command and a brief description of what it does.

The pwd command I looked at above shows the following:. Next comes synopsis , which shows the command any any options, or flags, that you can use with it. For pwd , there are two options: -L and -P. These options are explained in the description section:. When you look at a man page, you do so in Terminal through another command, called a pager ; by default, this is the less command.

What a pager does is allow you to view content in Terminal page by page, or line by line. There are two ways to do this with less. If you press Return, the page will move down one line. And if you press the spacebar, the page will scroll one page the number of lines visible in your Terminal window.

Try it on your Mac: Open Terminal, type man ls , then press Return. Depending on your Terminal settings, you may be able to scroll the Terminal window. If not, press Control-B to go back a page, and the spacebar, or Control-F, to go forward a page. Press Command-O, enter the name of a command, and click Open.

ManOpen is especially useful because you can choose specific sections to view from a popup menu, and you can navigate more easily than in Terminal with the less command. But you can also find man pages on the Web. Apple has a documentation repository with man pages here. You can click Alphabetic Index to get a list of all commands, then search for the one you want. No matter which route you choose, man pages open the door to a goldmine of information about the command line.

Man up The key to Terminal wisdom is the man command. The beginning of the man page for the pwd command. The pwd command I looked at above shows the following: pwd—return working directory name Next comes synopsis , which shows the command any any options, or flags, that you can use with it.

Some shells may provide a builtin pwd command which is similar or identical to this utility. Consult the builtin 1 manual page. The options are as follows: -L Display the logical current working directory.

If no options are specified, the -L option is assumed. Paging man pages When you look at a man page, you do so in Terminal through another command, called a pager ; by default, this is the less command. ManOpen lets you view man pages in a friendlier interface than Terminal.

find(1) - Linux man page

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.

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.

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.

I'm working on a lab that is supposed to help us better navigate the command line on a Linux system, but I'm getting stuck on man pages. We are supposed to use the man command to find a list of the man page sections, adn I can't seem to figure out how to do this. I've tried entering. I've also tried looking on Google to find what command I should use, but no luck there either. This will list all manual pages.

The find utility recursively descends the directory hierarchy for each path seeking files that match a Boolean expression written in the primaries specified below. Causes the file information and file type evaluated for each symbolic link encountered on the command line to be those of the file referenced by the link, and not the link itself. If the referenced file does not exist, the file information and type is for the link itself.
