.SH NAME
|
||||
extundelete \- utility to undelete files from an ext3 or ext4 partition.
|
||||
.SH SYNOPSIS
|
||||
.B extundelete
|
||||
.RI [ options ] " device-file" ...
|
||||
.br
|
||||
.SH DESCRIPTION
|
||||
.PP
|
||||
.\" TeX users may be more comfortable with the \fB<whatever>\fP and
|
||||
.\" \fI<whatever>\fP escape sequences to invode bold face and italics,
|
||||
.\" respectively.
|
||||
\fBextundelete\fP is a utility that can recover deleted files from an ext3 or ext4 partition
|
||||
.br
|
||||
extundelete uses the information stored in the partition's journal to attempt to recover
|
||||
a file that has been deleted from the partition.
|
||||
.br
|
||||
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!
|
||||
|
||||
.SH OPTIONS
|
||||
.TP
|
||||
.B \-\-version
|
||||
Prints the version number of extundelete.
|
||||
.TP
|
||||
.B \-\-help
|
||||
Print a brief usage summary for extundelete.
|
||||
.TP
|
||||
.B Partition name
|
||||
Name of the partition that has deleted files, such as /dev/sda3.
|
||||
.br
|
||||
Could also be the file name of a copy of the partition, such as that made with dd.
|
||||
.TP
|
||||
.B \-\-superblock
|
||||
Prints information about the filesystem from the superblock.
|
||||
.TP
|
||||
.B \-\-journal \-\-superblock
|
||||
Prints information about the journal from the journal's superblock.
|
||||
.TP
|
||||
.B \-\-inode #
|
||||
Prints the information from the inode number of the filesystem given, such as "\-\-inode 2".
|
||||
.TP
|
||||
.B \-\-block #
|
||||
Prints the contents of the block, called as "\-\-block 9652".
|
||||
.TP
|
||||
.B \-\-restore\-file path/to/deleted/file
|
||||
Attempts to restore the file which was deleted at the given filename, called as "\-\-restore-file dirname/filename".
|
||||
.TP
|
||||
.B \-\-restore\-inode #
|
||||
Used to restore inodes by number, called as "\-\-restore-inode 2569".
|
||||
.br
|
||||
Also accepts a list of inodes separated by only commas, such as "\-\-restore-inode 2569,5692,6925".
|
||||
.TP
|
||||
.B \-\-restore\-files filename
|
||||
Restores a list of files. First, construct a list of files in the same style as would be
|
||||
.br
|
||||
used in the \-\-restore\-file option, and save it to the file "filename".
|
||||
.br
|
||||
Then, this option may be used to attempt to restore those files with a single call to extundelete.
|
||||
.br
|
||||
This form also reduces redundancy from multiple calls parsing the journal multiple times.
|
||||
.TP
|
||||
.B \-\-restore\-all
|
||||
Restores all files possible to undelete to their names before deletion, when possible.
|
||||
Other files are restored to a filename like "file.NNNN".
|
||||
.TP
|
||||
.B \-\-restore\-directory path/of/directory
|
||||
Restores all files possible to link to specified directory to their names before deletion, when possible.
|
||||
.TP
|
||||
.B \-j journal_dev
|
||||
Specifies the device that is the external journal of the file system.
|
||||
.TP
|
||||
.B \-b block_number
|
||||
Specifies the block number of the backup superblock to be used when opening the file system.
|
||||
.TP
|
||||
.B \-B block_size
|
||||
Specifies the block size of the partition to be used when opening the file system.
|
||||
.TP
|
||||
.B \-\-before date
|
||||
Only restore files deleted before the date specified, which should be in the form of the number of seconds since the UNIX epoch.
|
||||
Use a shell command like
|
||||
.br
|
||||
$ date \-d "Aug 1 9:02" +%s
|
||||
.br
|
||||
to convert a human-readable date to the proper format. The conversion from the number of seconds to a readable format may be found
|
||||
by using either of the following:
|
||||
.br
|
||||
$ date \-d@1234567890
|
||||
.br
|
||||
$ perl \-le "print scalar localtime 1234567890"
|
||||
.TP
|
||||
.B \-\-after date
|
||||
Only restore files deleted after the date specified, which should be in the form of the number of seconds since the UNIX epoch.
|
||||
.br
|
||||
See the notes for the \-\-before option for more information.
