其实这个工具我已经知道很久了，前一段时间做试验，老是出问题。自己也解决不了。很纠结，很郁闷，很蛋疼。。。。
或许今天运气比较好，装下软件包，然后使用一下，呵呵，竟然成功了，而且删除文件的时候，使用的命令是rm -rf哦！
首先下载这个软件，下载地址：
http://code.google.com/p/ext3grep/downloads/list
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)
下面开始安装了哦。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.
