NAME
|
||
elvis, ex, vi - The editor
|
||
|
||
SYNOPSIS
|
||
elvis [flags] [+cmd] [files...]
|
||
|
||
DESCRIPTION
|
||
Elvis is a text editor which emulates vi/ex.
|
||
|
||
On systems which pass the program name as an argument, such as Unix and
|
||
Minix, you may also install elvis under the names "ex", "vi", "view", and
|
||
"input". These extra names would normally be links to elvis; see the
|
||
"ln" shell command.
|
||
|
||
When elvis is invoked as "vi", it behaves exactly as though it was
|
||
invoked as "elvis". However, if you invoke elvis as "view", then the
|
||
readonly option is set as though you had given it the "-R" flag. If you
|
||
invoke elvis as "ex", then elvis will start up in the colon command mode
|
||
instead of the visual command mode, as though you had given it the "-e"
|
||
flag. If you invoke elvis as "input" or "edit", then elvis will start up
|
||
in input mode, as though the "-i" flag was given.
|
||
|
||
OPTIONS
|
||
|
||
-r To the real vi, this flag means that a previous edit should be
|
||
recovered. Elvis, though, has a separate program, called elvrec(1),
|
||
for recovering files. When you invoke elvis with -r, elvis will
|
||
tell you to run elvrec.
|
||
|
||
-R This sets the "readonly" option, so you won't accidentally overwrite
|
||
a file.
|
||
|
||
-t tag
|
||
This causes elvis to start editing at the given tag.
|
||
|
||
-m [file]
|
||
Elvis will search through file for something that looks like an
|
||
error message from a compiler. It will then begin editing the
|
||
source file that caused the error, with the cursor sitting on the
|
||
line where the error was detected. If you don't explicitly name a
|
||
file, then "errlist" is assumed.
|
||
|
||
-e Elvis will start up in colon command mode.
|
||
|
||
-v Elvis will start up in visual command mode.
|
||
|
||
-i Elvis will start up in input mode.

|
||
|
||
|
||
-w winsize
|
||
Sets the "window" option's value to winsize.
|
||
|
||
+command or -c command
|
||
If you use the +command parameter, then after the first file is
|
||
loaded command is executed as an EX command. A typical example
|
||
would be "elvis +237 foo", which would cause elvis to start editing
|
||
foo and then move directly to line 237. The "-c command" variant
|
||
was added for UNIX SysV compatibility.
|
||
|
||
FILES
|
||
|
||
/tmp/elv*
|
||
During editing, elvis stores text in a temporary file. For UNIX,
|
||
this file will usually be stored in the /tmp directory, and the
|
||
first three characters will be "elv". For other systems, the
|
||
temporary files may be stored someplace else; see the version-
|
||
specific section of the documentation.
|
||
|
||
tags This is the database used by the :tags command and the -t option.
|
||
It is usually created by the ctags(1) program.
|
||
|
||
.exrc or elvis.rc
|
||
On UNIX-like systems, a file called ".exrc" in your home directory
|
||
is executed as a series of ex commands. A file by the same name may
|
||
be executed in the current directory, too. On non-UNIX systems,
|
||
".exrc" is usually an invalid file name; there, the initialization
|
||
file is called "elvis.rc" instead.
|
||
|

||
BUGS
|
||
There is no LISP support. Certain other features are missing, too.
|
||
|
||
Auto-indent mode is not quite compatible with the real vi. Among other
|
||
things, 0^D and ^^D don't do what you might expect.
|
||
|
||
Long lines are displayed differently. The real vi wraps long lines onto
|
||
multiple rows of the screen, but elvis scrolls sideways.

Many other people have worked to port elvis to various operating systems.
|
||
To see who deserves credit, run the :version command from within elvis,
|
||
or look in the system-specific section of the complete documentation.
