virecover

VIRECOVER(8)						    BSD System Manager's Manual 					      VIRECOVER(8)

NAME

     virecover -- report recovered vi edit sessions

SYNOPSIS

     /usr/libexec/virecover

DESCRIPTION

     The virecover utility sends emails to users who have vi(1) recovery files.

     This email gives the name of the file that was saved for recovery and instructions for recovering most, if not all, of the changes to the
     file.  This is done by using the -r option with vi(1).  See the -r option in vi(1) for details.

     If the backup files have the execute bit set or are zero length, then they have not been modified, so virecover deletes them to clean up.
     virecover also removes recovery files that are corrupted, zero length, or do not have a corresponding backup file.

     virecover is normally run automatically at boot time using /etc/rc.d/virecover.

FILES

     /var/tmp/vi.recover/recover.*  vi(1) recovery files
     /var/tmp/vi.recover/vi.*	    vi(1) editor backup files

SEE ALSO

     vi(1), rc.conf(5)

HISTORY

     This script, previously known as recover.script, is from nvi and was added to NetBSD in 1996.  It was renamed in 2001.
