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".
