ex(1) | ex(1) |
magic | Affect the interpretation of characters in regular expressions and substitution replace- |
| ment strings (see Regular Expressions and Replacement Strings above). Reversed by |
| nomagic. The ex, vi, and view default is magic. The edit and vedit default |
| is nomagic. |
mesg | Allows other users to use the write command (see write(1)) to send messages to |
| your terminal, possibly disrupting the screen display. Unsetting this option |
| (nomesg) blocks write permission to your terminal from other system users while |
| you are using the editor. Reversed by nomesg. The default is mesg. |
modelines (ml) | If set when the editor reads in a ®le, any ex commands embedded in the ®rst ®ve and |
| last ®ve lines of the ®le are executed after .exrc and EXINIT commands are pro- |
| cessed but before editing control is given to the user. The ex commands must be |
| pre®xed by ex: or vi: and terminated by : in a single line. Any number of other |
| characters with the exception of the colon (:) can precede or follow the embedded |
| command. Reversed by nomodelines (noml). The default is nomodelines . |
novice | Use the version of the editor available for novices, known as edit or vedit. |
| Reversed by nonovice. The ex, vi, and view default is nonovice. The edit, |
| and vedit default is novice. |
number (nu) | Cause lines to be printed with line numbers. Reversed by nonumber (nonu). The |
| default is nonumber. |
optimize (opt) | Suppress automatic carriage returns on terminals that do not support direct cursor |
| addressing. This streamlines text output in certain situations such as when printing |
| multiple lines that contain leading whitespace. Reversed by nooptimize (noopt). |
| The default is nooptimize. |
paragraphs=
The value of this option is a string whose successive pairs of characters specify the names of
| If any macros have a | |
| the missing second character in the name. To type a space character in such situa- | |
| tions, precede the space with a backslash (\) to prevent the editor from interpreting it | |
| as a delimiter. |
|
| The default is paragraphs=IPLPPPQPP\ LIpplpipnpbp. | |
prompt | When set, command mode input is prompted for with a colon (:); when unset, no | |
| prompt is displayed. Reversed by noprompt. The default is prompt. | |
readonly (ro) | Set the readonly ¯ag for the ®le being edited, thus preventing accidental overwrit- | |
| ing at the end of the session. This option is equivalent to invoking ex, edit, vi, or | |
| vedit with the | |
| noreadonly (noro). The ex, edit, vi, and vedit default is noreadonly. | |
| The view default is readonly. |
|
redraw | Simulate an intelligent terminal on a dumb terminal. During input mode, lines are | |
| continuously reprinted as text is entered. Since this is likely to require a large | |
| amount of output to the terminal, it is useful only at high transmission speeds. If | |
| noredraw is set, lines are reprinted only when input mode is terminated and | |
| deleted lines are marked with an @ in the left margin. Reversed by noredraw. The | |
| default is redraw. |
|
remap | If set, macro translation allows for macros de®ned in terms of other macros; transla- | |
| tion continues until the ®nal product is obtained. If unset, a | |
| is done. Reversed by noremap. The default is remap. | |
report=n | The value of n gives the number of lines that must be changed by a command before a | |
| report is displayed on the number of lines affected. If n is 5, then changes are | |
| reported for 6 or more lines. The ex, vi, and view default is report=5. The | |
| edit, and vedit default is report=1. |
|
scroll=n | The value of n determines the number of lines scrolled by a ÃD command and the | |
| number of lines displayed by the z command (twice the value of scroll). The default is | |
| half the value of the window option. |
