Option |
Default |
Description |
backup |
|
A string describing a backup filename to use. The current contents of a
file are saved in this file before writing the new data out.
For example,
a value of "N%.bak" causes nvi to
include a version number at the end of the file; version numbers are
always incremented. |
cdpath |
environment variable CDPATH,
or current directory |
A search path for the :cd command. |
cedit |
|
When the first character of this string is entered on the colon
command line, nvi opens a new window on the command
history that you can then edit. Hitting RETURN
on any given line executes that line.
ESC is a good choice for this option.
(Use ^V ^[ to enter it.) |
comment |
nocomment |
If the first non-empty line begins with /*,
//, or #, nvi
skips the comment text before displaying the file. This
avoids displaying long, boring legal notices. |
directory (dir) |
environment variable TMPDIR,
or /tmp |
The directory where nvi puts its temporary files. |
extended |
noextended |
Searches use egrep-style extended regular expressions. |
filec |
|
When the first character of this string is entered on the colon
command line, nvi treats the blank delimited word
in front of the cursor as if it had an * appended
to it and does shell-style filename expansion.
ESC is a also good choice for this option.
(Use ^V ^[ to enter it.)
When this character is the same as for the cedit option,
command line editing is performed only when the character is entered
as the first character on the colon command line. |
iclower |
noiclower |
Make all regular expression searches case insensitive, as long
as the search pattern contains no uppercase letters. |
leftright |
noleftright |
Long lines scroll the screen left to right, instead of wrapping. |
lock |
lock |
nvi attempts to get an exclusive
lock on the file. Editing a file that cannot be locked
creates a read-only session. |
octal |
nooctal |
Displays unknown characters in octal, instead of in hexadecimal. |
path |
|
A colon-separated list of directories in which nvi
will look for the file to be edited. |
recdir |
/var/tmp/vi.recover |
The directory where recovery files are stored. |
ruler |
noruler |
Displays the row and column of the cursor. |
searchincr |
nosearchincr |
Searches are done incrementally. |
secure |
nosecure |
Turns off access to external programs via text filtering
(:r!, :w!), disables
the vi mode ! and
^Z commands, and the ex mode
!,
shell,
stop,
and
suspend
commands.
Once set, it cannot be changed. |
shellmeta |
~{[*?$''"\ |
When any of these characters appear in a filename argument to an
ex command, the argument is expanded by the
program named by the shell option. |
showmode (smd) |
noshowmode |
Displays a string in the status
line showing the current mode. Displays an *
if the file has been modified. |
sidescroll |
16 |
The number of columns by which the screen is shifted left or right
when leftright is true. |
taglength (tl) |
0 |
Defines number of characters that are significant for tags.
Default (zero) means that all characters are significant. |
tags (tag) |
tags /var/db/libc.tags /sys/kern/tags |
The list of possible tag files. |
tildeop |
notildeop |
The ~ command takes an
associated motion, not just a preceding count. |
wraplen (wl) |
0 |
Identical to the wrapmargin option,
except that it specifies the number of characters from the
left margin at which the line will be split.
The value of wrapmargin
overrides wraplen. |
