今天给大家带来在Linux上怎么使用ext3grep恢复文件,在Linux上使用ext3grep恢复文件的方法,让您轻松解决问题。

  Linux系统操作中,有时会不小心删除重要文件,而能够恢复删除文件的软件有很多,ext3grep就是其中的一种,ext3grep在使用中需要用到不少命令,下面小编就给大家介绍下Linux使用ext3grep的方法。

  步骤:

  目前的最新版本是:ext3grep-0.10.2.tar.gz

  我系统的环境是:虚拟机

  [root@localhost bin]# uname -a

  Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux

  [root@localhost bin]# cat /etc/issue

  Red Hat Enterprise Linux Server release 5.4 (Tikanga)

     安装很简单

  tar zxvf ext3grep-0.10.2.tar.gz

  cd ext3grep-0.10.2

  。/configure --prefix=/usr/local/ext3grep

  make

  make install

  顺利安装完成。

  然后进入么安装目录看一下,只有一个bin

  [root@localhost ext3grep]# pwd

  /usr/local/ext3grep

  [root@localhost ext3grep]# ls

  bin

  进到bin里面看一下

  [root@localhost ext3grep]# cd bin

  [root@localhost bin]# ls

  ext3grep

  我们可以看一下帮助,下面是部分

  [root@localhost bin]# 。/ext3grep -h

  Running ext3grep version 0.10.2

  。/ext3grep: invalid option -- h

  No action specified; implying --superblock.

  Usage: 。/ext3grep [options] [--] device-file

  Options:

  --version, -[vV] Print version and exit successfully.

  --help, Print this help and exit successfully.

  --superblock Print contents of superblock in addition to the rest.

  If no action is specified then this option is implied.

  --print Print content of block or inode, if any.

  --ls Print directories with only one line per entry.

  This option is often needed to turn on filtering.

  --accept filen Accept ‘filen’ as a legal filename. Can be used multi-

  ple times. If you change any --accept you must remove

  BOTH stage* files!

  --accept-all Simply accept everything as filename.

  --journal Show content of journal.

  --show-path-inodes Show the inode of each directory component in paths.

  Filters:

  --group grp Only process group ‘grp’。

  --directory Only process directory inodes.

  --after dtime Only entries deleted on or after ‘dtime’。

  --before dtime Only entries deleted before ‘dtime’。

  --deleted Only show/process deleted entries.

  --allocated Only show/process allocated inodes/blocks.

  --unallocated Only show/process unallocated inodes/blocks.

  --reallocated Do not suppress entries with reallocated inodes.

  Inodes are considered ‘reallocated’ if the entry

  is deleted but the inode is allocated, but also when

  the file type in the dir entry and the inode are

  different.

  --zeroed-inodes Do not suppress entries with zeroed inodes. Linked

  entries are always shown, regardless of this option.

  --depth depth Process directories recursively up till a depth

  of ‘depth’。

  Actions:

  --inode-to-block ino Print the block that contains inode ‘ino’。

  --inode ino Show info on inode ‘ino’。

  If --ls is used and the inode is a directory, then

  the filters apply to the entries of the directory.

  If you do not use --ls then --print is implied.

  --block blk Show info on block ‘blk’。

  If --ls is used and the block is the first block

  of a directory, then the filters apply to entries

  of the directory.

  If you do not use --ls then --print is implied.

  --histogram=[atime|ctime|mtime|dtime|group]

  Generate a histogram based on the given specs.

  Using atime, ctime or mtime will change the

  meaning of --after and --before to those times.

  --journal-block jblk Show info on journal block ‘jblk’。

  --journal-transaction seq

  Show info on transaction with sequence number ‘seq’。

  --dump-names Write the path of files to stdout.

  This implies --ls but suppresses it‘s output.

  --search-start str Find blocks that start with the fixed string ’str‘。

  --search str Find blocks that contain the fixed string ’str‘。

  --search-inode blk Find inodes that refer to block ’blk‘。

  --search-zeroed-inodes Return allocated inode table entries that are zeroed.

  --inode-dirblock-table dir

  Print a table for directory path ’dir‘ of directory

  block numbers found and the inodes used for each file.
