.SH NAME
|
|
elvrec - Recover the modified version of a file after a crash
|
|
.SH SYNOPSIS
|
|
.nf
|
|
\fBelvrec\fP [\fIpreservedfile\fP [\fInewfile\fR]]
|
|
.fi
|
|
.SH DESCRIPTION
|
|
.PP
|
|
If you're editing a file when \fIelvis\fP dies, the system crashes, or power fails,
|
|
the most recent version of your text will be preserved.
|
|
The preserved text is stored in a special directory; it does NOT overwrite
|
|
your text file automatically.
|
|
.PP
|
|
The \fIelvrec\fP program locates the preserved version of a given file,
|
|
and writes it over the top of your text file -- or to a new file, if you prefer.
|
|
The recovered file will have nearly all of your changes.
|
|
.PP
|
|
To see a list of all recoverable files, run \fIelvrec\fP with no arguments.
|
|
.SH FILES
|
|
.IP /usr/preserve/p*
|
|
The text that was preserved when \fIelvis\fP died.
|
|
.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
|
|
\fIelvrec\fP is very picky about filenames.
|
|
You must tell it to recover the file using exactly the same pathname as
|
|
when you were editing it.
|
|
The simplest way to do this is to go into the same directory that you were
|
|
editing, and invoke \fIelvrec\fP with the same filename as \fIelvis\fP.
|
|
If that doesn't work, then try running \fIelvrec\fP with no arguments,
|
|
to see exactly which pathname it is using for the desired file.
|
|
.PP
|
|
Due to the permissions on the /usr/preserve directory, on UNIX systems
|
|
\fIelvrec\fP must be run as superuser.
|
|
This is accomplished by making the \fIelvrec\fP executable be owned by "root"
|
|
and setting its "set user id" bit.
|
|
.PP
|
|
If you're editing a nameless buffer when \fIelvis\fP dies, then \fIelvrec\fP
|
|
will pretend that the file was named "foo".
