extundelete - utility to undelete files from an ext3 or ext4 partition.
is a utility that can recover deleted files from an ext3 or
extundelete uses the information stored in the partition's journal to attempt to
recover a file that has been deleted from the partition.
There is no guarantee that any particular file will be able to be undeleted, so
always try to have a good backup system in place, or at least put one in place
after recovering your files!

the number of seconds to a readable format may be found by using either of
$ date -d@1234567890
$ perl -le "print scalar localtime 1234567890"
- --after date
- Only restore files deleted after the date specified, which
