||
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 version
|
||
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".
