ELVREC                                                     ELVREC




          NAME
               elvrec  - Recover  the modified  version of  a file  after a
               crash

          SYNOPSIS
               elvrec [preservedfile [newfile]]

          DESCRIPTION
               If  you're  editing  a  file  when  elvis dies,  the  system
               crashes,  or power  fails, the most  recent version  of your
               text will  be preserved.  The preserved text  is stored in a
               special  directory; it  does  NOT overwrite  your text  file
               automatically.

               The elvrec program  locates the preserved version of a given
               file, and writes it over the  top of your text file -- or to
               a new  file, if  you prefer.   The recovered file  will have
               nearly all of your changes.

               To see  a list of all recoverable files,  run elvrec with no
               arguments.

          FILES
               /usr/preserve/p*
                    The text that was preserved when elvis died.

               /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
               elvrec is  very picky about filenames.  You  must tell it to
               recover the file using exactly the same pathname as when you
               were editing it.  The simplest way  to do this is to go into
               the same directory  that you were editing, and invoke elvrec
               with the same filename as elvis.  If that doesn't work, then
               try running  elvrec with no arguments,  to see exactly which
               pathname it is using for the desired file.

               Due to  the permissions  on the /usr/preserve  directory, on
               UNIX  systems elvrec  must  be run  as  superuser.  This  is
               accomplished  by making  the elvrec  executable be  owned by
               "root" and setting its "set user id" bit.

               If you're  editing a nameless  buffer when elvis  dies, then
               elvrec will pretend that the file was named "foo".
