elvprsv - Preserve the the modified version of a file after a crash.
elvprsv ["-why elvis died"] /tmp/filename...
elvprsv -R /tmp/filename...
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
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.
The temporary file that elvis was using when it died.
The text that is preserved by elvprsv.
A text file which lists the names of all preserved files, and the
names of the /usr/preserve/p* files which contain their preserved
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"
If you're editing a nameless buffer when elvis dies, then elvprsv will
pretend that the file was named "foo".
