- 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.

- ELVPRSV(8) Minix Programmer's Manual ELVPRSV(8)
- If you're editing a nameless buffer when elvis dies, then elvprsv will
- pretend that the file was named "foo".
