| 3 | elvprsv - Preserve the the modified version of a file after a crash.
|

| 4 | .SH SYNOPSIS

|

| 6 | \fB\fBelvprsv\fP ["-\fIwhy elvis died\fP"] /tmp/\fIfilename\fP...

| 9 | .SH DESCRIPTION
|
|---|
| 10 | .PP
|
|---|
| 11 | \fIelvprsv\fP preserves your edited text after \fIelvis\fP dies.
|
|---|
| 12 | The text can be recovered later, via the \fIelvprsv\fP program.
|
|---|
| 13 | .PP
|
|---|
| 14 | For UNIX-like systems,
|
|---|
| 15 | you should never need to run this program from the command line.
|
|---|
| 16 | It is run automatically when \fIelvis\fP is about to die,
|
|---|
| 17 | and it should be run (via /etc/rc) when the computer is booted.
|
|---|
| 18 | THAT'S ALL!
|
|---|
| 19 | .PP
|
|---|
| 20 | For non-UNIX systems such as MS-DOS, you can either use \fIelvprsv\fP
|
|---|
| 21 | the same way as under UNIX systems (by running it from your AUTOEXEC.BAT file),
|
|---|
| 22 | or you can run it separately with the "-R" flag to recover the files
|
|---|
| 23 | in one step.
|
|---|
| 24 | .PP
|
|---|
| 25 | If you're editing a file when \fIelvis\fP dies
|
|---|
| 26 | (due to a bug, system crash, power failure, etc.)
|
|---|
| 27 | then \fIelvprsv\fP will preserve the most recent version of your text.
|
|---|
| 28 | The preserved text is stored in a special directory; it does NOT overwrite
|
|---|
| 29 | your text file automatically.
|
|---|
| 30 | .PP
|
|---|
| 31 | \fIelvprsv\fP will send mail to any user whose work it preserves,
|
|---|
| 32 | if your operating system normally supports mail.
|
|---|
| 33 | .SH FILES
|
|---|
| 34 | .IP /tmp/elv*
|
|---|
| 35 | The temporary file that \fIelvis\fP was using when it died.
|
|---|
| 36 | .IP /usr/preserve/p*
|
|---|
| 37 | The text that is preserved by \fIelvprsv\fP.
|
|---|
| 38 | .IP /usr/preserve/Index
|
|---|
| 39 | A text file which lists the names of all preserved files, and the names
|
|---|
| 40 | of the /usr/preserve/p* files which contain their preserved text.
|
|---|
| 41 | .SH BUGS
|
|---|
| 42 | .PP
|
|---|
| 43 | Due to the permissions on the /usr/preserve directory, on UNIX systems
|
|---|
| 44 | \fIelvprsv\fP must be run as superuser.
|
|---|
| 45 | This is accomplished by making the \fIelvprsv\fP executable be owned by "root"
|
|---|
| 46 | and turning on its "set user id" bit.
|
|---|
| 47 | .PP
|
|---|
| 48 | If you're editing a nameless buffer when \fIelvis\fP dies, then \fIelvprsv\fP will pretend
|
|---|
| 49 | that the file was named "foo".
