ELVPRSV ELVPRSV
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".
