emacs Editor.
emacs [<command command-line switches>] [<file1>
								<file2>...]

emacs is a powerful editor that can actually do more than edit files. It has an extensive information system, which can be accessed in emacs with the key sequence <Ctrl+h i> (holding the Control key and h then i). The information system can be navigated using the arrow keys to move around and pressing the Enter key to make a selection.
emacs has an interactive help facility, <Ctrl+h>. The information facility is one of the types of help available. A help tutorial is available with <Ctrl+h t>. Help Apropos <Ctrl+h a> helps the user find a command given its functionality. Help character <Ctrl+h c> describes a given character's effect.
The following are emacs options of general interest:
<file> Edits the specified <file>.
+<number> Moves the cursor to the line number specified by <number>. (Do not include a space between + and <number>.)
-q Does not load an init file.
-u <user> Loads the init file of the specified <user>.
-t <file> Uses the specified <file> as the terminal instead of using stdin/stdout. This must be the first argument specified in the command line.
-nw Tells emacs not to use its special X interface. If this option is given when invoking emacs in an xterm(1) window, the emacs display is done in that window. This must be the first option specified in the command line.
The following are basic emacs key sequences:
Ctrl+x Ctrl+s Saves the file.
Ctrl+x Ctrl+c Exits emacs.
