NAME
elvprsv - Preserve the the modified version of a file after
a crash.
SYNOPSIS
elvprsv ["-_w_h_y _e_l_v_i_s _d_i_e_d"] /tmp/_f_i_l_e_n_a_m_e...
elvprsv -R /tmp/_f_i_l_e_n_a_m_e...
DESCRIPTION
_e_l_v_p_r_s_v preserves your edited text after _e_l_v_i_s dies. The
text can be recovered later, via the _e_l_v_p_r_s_v program.
For UNIX-like systems, you should never need to run this
program from the command line. It is run automatically when
_e_l_v_i_s 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
_e_l_v_p_r_s_v 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 _e_l_v_i_s dies (due to a bug, sys-
tem crash, power failure, etc.) then _e_l_v_p_r_s_v 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.
_e_l_v_p_r_s_v will send mail to any user whose work it preserves,
if your operating system normally supports mail.
FILES
/tmp/elv*
The temporary file that _e_l_v_i_s was using when it died.
/usr/preserve/p*
The text that is preserved by _e_l_v_p_r_s_v.
/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 _e_l_v_p_r_s_v must be run as superuser. This is
accomplished by making the _e_l_v_p_r_s_v executable be owned by
"root" and turning on its "set user id" bit.
If you're editing a nameless buffer when _e_l_v_i_s dies, then
_e_l_v_p_r_s_v will pretend that the file was named "foo".
