This manual page is the one provided with the nex versions of the ex text editors. nex are intended as bug-for-bug compatible replacements for the original Fourth Berkeley Software Distribution (4BSD) ex and vi programs. For the rest of this manual page, nex is used only when it's necessary to distinguish it from the historic implementations of ex.
This manual page is intended for users already familiar with ex. Anyone else should almost certainly read a good tutorial on the editor before this manual page. If you're in an unfamiliar environment, and you absolutely have to get work done immediately, read the section after the options description, entitled FAST STARTUP. It's probably enough to get you going.
The following options are available:
| |
Execute cmd on the first file loaded. Particularly useful for initial positioning in the file, although cmd is not limited to positioning commands. This is the POSIX 1003.2 interface for the historic "+cmd" syntax. nex supports both the old and new syntax. | |
| |
Start editing in ex mode, as if the command name were ex. | |
| |
Don't copy the entire file when first starting to edit. (The default is to make a copy in case someone else modifies the file during your edit session.) | |
| |
Start editing in read-only mode, as if the command name was view, or the readonly option was set. | |
| |
Recover the specified files, or, if no files are specified,
list the files that could be recovered.
If no recoverable files by the specified name exist,
the file is edited as if the
| |
| |
Run with the secure edit option set, disallowing all access to external programs. | |
| |
Enter batch mode; applicable only to ex edit sessions. Batch mode is useful when running ex scripts. Prompts, informative messages and other user oriented messages are turned off, and no startup files or environment variables are read. This is the POSIX 1003.2 interface for the historic "-" argument. nex supports both the old and new syntax. | |
| |
Start editing at the specified tag (seectags(1)). | |
| |
Start editing in vi mode, as if the command name was vi. | |
| |
Set the initial window size to the specified number of lines. | |
Command input for
ex
is read from the standard input.
In the
vi
interface, it is an error if standard input is not a terminal.
In the
ex
interface, if standard input is not a terminal,
ex
will read commands from it regardless; however, the session will be a
batch mode session, exactly as if the
vi is a screen editor. This means that it takes up almost the entire screen, displaying part of the file on each screen line, except for the last line of the screen. The last line of the screen is used for you to give commands to vi, and for vi to give information to you.
The other fact that you need to understand is that vi is a modeful editor, i.e., you are either entering text or you are executing commands, and you have to be in the right mode to do one or the other. You will be in command mode when you first start editing a file. There are commands that switch you into input mode. There is only one key that takes you out of input mode, and that is the <escape> key.
In this manual, key names are denoted with la and ra, e.g., <escape> means the "escape" key, usually labeled "Esc" on your terminal's keyboard. If you're ever confused as to which mode you're in, keep entering the <escape> key until vi beeps at you. Generally, vi will beep at you if you try and do something that's not allowed. It will also display error messages.
To start editing a file, enter the following command:
$ vi file
The command you should enter as soon as you start editing is:
:set verbose showmode
This will make the editor give you verbose error messages and display the current mode at the bottom of the screen.
The commands to move around the file are:
h | Move the cursor left one character. |
j | Move the cursor down one line. |
k | Move the cursor up one line. |
l | Move the cursor right one character. |
< cursor-arrows> | |
The cursor arrow keys should work, too. | |
/text | Search for the string "text" in the file, and move the cursor to its first character. |
The commands to enter new text are:
a | Append new text, after the cursor. |
i | Insert new text, before the cursor. |
o | Open a new line below the line the cursor is on, and start entering text. |
O | Open a new line above the line the cursor is on, and start entering text. |
< escape> | |
Once you've entered input mode using one of the a, i, o or O commands, use < escape> to quit entering text and return to command mode. | |
The commands to copy text are:
yy | Copy the line the cursor is on. |
p | Append the copied line after the line the cursor is on. |
The commands to delete text are:
dd | Delete the line the cursor is on. |
x | Delete the character the cursor is on. |
The commands to write the file are:
:w | Write the file back to the file with the name that you originally used as an argument on the vi command line. |
:w file_name | |
Write the file back to the file with the name file_name. | |
The commands to quit editing and exit the editor are:
:q | Quit editing and leave vi (if you've modified the file, but not saved your changes, vi will refuse to quit). |
:q! | Quit, discarding any modifications that you may have made. |
One final caution: Unusual characters can take up more than one column on the screen, and long lines can take up more than a single screen line. The above commands work on "physical" characters and lines, i.e., they affect the entire line no matter how many screen lines it takes up and the entire character no matter how many screen columns it takes up.
The following strings have special meanings in the ex version of regular expressions:
All buffers are either in line mode or character mode. Inserting a buffer in line mode into the text creates new lines for each of the lines it contains, while a buffer in character mode creates new lines for any lines other than the first and last lines it contains. The first and last lines are inserted at the current cursor position, becoming part of the current line. If there is more than one line in the buffer, the current line itself will be split. All ex commands which store text into buffers do so in line mode. The behaviour of vi commands depend on their associated motion command:
The ex command display buffers displays the current mode for each buffer.
Buffers named 'a' through 'z' may be referred to using their uppercase equivalent, in which case new content will be appended to the buffer, instead of replacing it.
Buffers named '1' through '9' are special. A region of text modified using the c (change) or d (delete) commands is placed into the numeric buffer '1' if no other buffer is specified and if it meets one of the following conditions:
Before this copy is done, the previous contents of buffer '1' are moved into buffer '2', '2' into buffer '3', and so on. The contents of buffer '9' are discarded. Note that this rotation occurs regardless of the user specifying another buffer. In vi, text may be explicitly stored into the numeric buffers. In this case, the buffer rotation occurs before the replacement of the buffer's contents. The numeric buffers are only available in vi mode.
bigword | |
A set of non-whitespace characters. | |
buffer | Temporary area where commands may place text. If not specified, the default buffer is used. See also BUFFERS, above. |
count | A positive number used to specify the desired number of iterations of a command. It defaults to 1 if not specified. |
motion | A cursor movement command which indicates the other end of the affected region of text, the first being the current cursor position. Repeating the command character makes it affect the whole current line. |
word | A sequence of letters, digits or underscores. |
buffer and count, if both present, may be specified in any order. motion and count, if both present, are effectively multiplied together and considered part of the motion.
