Usage
To read a manual page for a Unix command, one can use
manat a shell prompt: for example, "man ftp". In order to simplify navigation through the output, man generally uses the less terminal pager.
Pages are traditionally referred to using the notation "name(section)": for example, ftp. The same page name may appear in more than one section of the manual, as when the names of system calls, user commands, or macro packages coincide. Examples are man and man, or exit and exit.
The syntax for accessing the non-default manual section varies between different man implementations. On Solaris, for example, the syntax for reading printf is:
On Linux and BSD derivatives the same invocation would be:
man 3 printfwhich searches for printf in section 3 of the man pages.

Famous quotes containing the word usage:
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
“...Often the accurate answer to a usage question begins, “It depends.” And what it depends on most often is where you are, who you are, who your listeners or readers are, and what your purpose in speaking or writing is.”
—Kenneth G. Wilson (b. 1923)
