- .TH ELVPRSV 8
- .SH NAME
- elvprsv - Preserve the the modified version of a file after a crash.
- .SH SYNOPSIS
- .nf
- fBfBelvprsvfP ["-fIwhy elvis diedfP"] /tmp/fIfilenamefP...
- fBfBelvprsvfP -R /tmp/fIfilenamefP...
- .fi
- .SH DESCRIPTION
- .PP
- fIelvprsvfP preserves your edited text after fIelvisfP dies.
- The text can be recovered later, via the fIelvprsvfP program.
- .PP
- For UNIX-like systems,
- you should never need to run this program from the command line.
- It is run automatically when fIelvisfP is about to die,
- and it should be run (via /etc/rc) when the computer is booted.
- THAT'S ALL!
- .PP
- For non-UNIX systems such as MS-DOS, you can either use fIelvprsvfP
- 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.
- .PP
- If you're editing a file when fIelvisfP dies
- (due to a bug, system crash, power failure, etc.)
- then fIelvprsvfP 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.
- .PP
- fIelvprsvfP will send mail to any user whose work it preserves,
- if your operating system normally supports mail.
- .SH FILES
- .IP /tmp/elv*
- The temporary file that fIelvisfP was using when it died.
- .IP /usr/preserve/p*
- The text that is preserved by fIelvprsvfP.
- .IP /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.
- .SH BUGS
- .PP
- Due to the permissions on the /usr/preserve directory, on UNIX systems
- fIelvprsvfP must be run as superuser.
- This is accomplished by making the fIelvprsvfP executable be owned by "root"
- and turning on its "set user id" bit.
- .PP
- If you're editing a nameless buffer when fIelvisfP dies, then fIelvprsvfP will pretend
- that the file was named "foo".
