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.
