ecryptfs-rewrite-file — force a file to be rewritten (reencrypted) in the lower filesystem

Synopsis

ecryptfs-rewrite-file [file1] [file2] [file3] ...

Description

This script takes one or more files/directories/symlinks as arguments, moves each of them to a temporary file, and then moves them back to the original name. This causes the file to be rewritten (and reencrypted) in the lower filesystem.

This script may be combined with find(1) and xargs(1) to rewrite an entire eCryptfs mountpoint, unmount, and sync:

find . -xdev -print0 | xargs -r -0 /usr/bin/ecryptfs-rewrite-file
ecryptfs-umount-private
sync

It is advised that this script is executed in runlevel 1 or 3, to avoid simultaneous writes and race conditions with targeted files.

USING THIS SCRIPT WHILE GNOME, KDE, OR OTHER APPLICATIONS ARE RUNNING MAY CAUSE DATA LOSS.
