elvis, ex, vi - The editor
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>elvis</STRONG> [<EM>flags</EM>] [<STRONG>+</STRONG><EM>cmd</EM>] [<EM>files</EM>...]
</PRE>
<H2>DESCRIPTION</H2><PRE>
<STRONG>Elvis</STRONG> is a text editor which emulates <STRONG>vi</STRONG>/<STRONG>ex</STRONG>.
On systems which pass the program name as an argument, such as Unix and
Minix, you may also install <STRONG>elvis</STRONG> under the names "ex", "vi", "view", and
"input". These extra names would normally be links to elvis; see the
"ln" shell command.
When <STRONG>elvis</STRONG> is invoked as "vi", it behaves exactly as though it was
invoked as "elvis". However, if you invoke <STRONG>elvis</STRONG> as "view", then the
readonly option is set as though you had given it the "-R" flag. If you
invoke <STRONG>elvis</STRONG> as "ex", then <STRONG>elvis</STRONG> 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 <STRONG>elvis</STRONG> as "input" or "edit", then <STRONG>elvis</STRONG> will start up
in input mode, as though the "-i" flag was given.
</PRE>
<H2>OPTIONS</H2><PRE>
<STRONG>-r</STRONG> To the real vi, this flag means that a previous edit should be
recovered. <STRONG>Elvis</STRONG>, though, has a separate program, called <STRONG><A HREF="../man1/elvrec.1.html">elvrec(1)</A></STRONG>,
for recovering files. When you invoke <STRONG>elvis</STRONG> with -r, <STRONG>elvis</STRONG> will
tell you to run <STRONG>elvrec</STRONG>.
<STRONG>-R</STRONG> This sets the "readonly" option, so you won't accidentally overwrite
a file.
<STRONG>-t</STRONG> <EM>tag</EM>
This causes <STRONG>elvis</STRONG> to start editing at the given tag.
<STRONG>-m</STRONG> [<EM>file</EM>]
<STRONG>Elvis</STRONG> will search through <EM>file</EM> 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
<EM>file</EM>, then "errlist" is assumed.
<STRONG>-e</STRONG> <STRONG>Elvis</STRONG> will start up in colon command mode.
<STRONG>-v</STRONG> <STRONG>Elvis</STRONG> will start up in visual command mode.
<STRONG>-i</STRONG> <STRONG>Elvis</STRONG> will start up in input mode.
<STRONG>-w</STRONG> <EM>winsize</EM>
Sets the "window" option's value to <EM>winsize</EM>.
<STRONG>+</STRONG><EM>command</EM> or <STRONG>-c</STRONG> <EM>command</EM>
If you use the +<EM>command</EM> parameter, then after the first file is
loaded <EM>command</EM> is executed as an EX command. A typical example
would be "elvis +237 foo", which would cause <STRONG>elvis</STRONG> to start editing
foo and then move directly to line 237. The "-c <EM>command</EM>" variant
was added for UNIX SysV compatibility.

<H2>FILES</H2><PRE>
/tmp/elv*
During editing, <STRONG>elvis</STRONG> 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 <STRONG>:tags</STRONG> command and the <STRONG>-t</STRONG> option.
It is usually created by the <STRONG><A HREF="../man1/ctags.1.html">ctags(1)</A></STRONG> program.
.exrc or elvis.rc
On UNIX-like systems, a file called ".exrc" in your home directory
is executed as a series of <STRONG>ex</STRONG> 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.

<H2>BUGS</H2><PRE>
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 <STRONG>elvis</STRONG> scrolls sideways.

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