elvprsv

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".
