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.

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.

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.

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. We'll try to address the first three failings in this document. Man pages are the standard documentation for every Unix; you're sure to come across a reference before too long of the form:.
