ELVPRSV(8) System Manager's Manual ELVPRSV(8)NAME
elvprsv - Preserve the the modified version of a file after a crash.
SYNOPSIS
elvprsv ["-why elvis died"] /tmp/filename...
elvprsv -R /tmp/filename...
DESCRIPTION
elvprsv preserves your edited text after elvis dies. The text can be recovered later, via the elvprsv program.
For UNIX-like systems, you should never need to run this program from the command line. It is run automatically when elvis is about to
die, and it should be run (via /etc/rc) when the computer is booted. THAT'S ALL!
For non-UNIX systems such as MS-DOS, you can either use elvprsv the same way as under UNIX systems (by running it from your AUTOEXEC.BAT
file), or you can run it separately with the "-R" flag to recover the files in one step.
If you're editing a file when elvis dies (due to a bug, system crash, power failure, etc.) then elvprsv will preserve the most recent ver-
sion of your text. The preserved text is stored in a special directory; it does NOT overwrite your text file automatically.
elvprsv will send mail to any user whose work it preserves, if your operating system normally supports mail.
FILES
/tmp/elv*
The temporary file that elvis was using when it died.
/usr/preserve/p*
The text that is preserved by elvprsv.
/usr/preserve/Index
A text file which lists the names of all preserved files, and the names of the /usr/preserve/p* files which contain their preserved
text.
BUGS
Due to the permissions on the /usr/preserve directory, on UNIX systems elvprsv must be run as superuser. This is accomplished by making
the elvprsv executable be owned by "root" and turning on its "set user id" bit.
If you're editing a nameless buffer when elvis dies, then elvprsv will pretend that the file was named "foo".

ELVIS(1) General Commands Manual ELVIS(1)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 com-
mand 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" vari-
ant 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 initializa-
tion 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.
