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 or VMS, 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  sepa-
       rately  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 pre-
       serve the most recent version of your text.  The preserved
       text  is  stored in a special directory; it does NOT over-
       write your text file automatically.  (If the  preservation
       directory  hasn't been set up correctly, then elvprsv will
       simply send you a mail message descrining how to  manually
       run elvprsv.)

       elvprsv  will  send  mail  to  any user whose work it pre-
       serves, 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".
