Sometimes we mistakenly delete files under AIX.
In fact I do have such awkward experience that I run "rm foo *" although my intention is "rm foo*".
Now I want to provide my tool named j2restore which can help you if your deleted file is in a jfs2 file system.

# ./j2restore
Usage: j2restore [-r] [-i inode-number] [-v]
-r means report mode. It will report detail info for those deleted files under this file system and do nothing else.
-i inode-number means only restore/report the specific file whose inode number is inode-number
-v print j2restore version and author info file system name, for example: /home, /dev/hd1, etc.

-v print j2restore version and author info file system name, for example: /home, /dev/hd1, etc.
Examples:
1. To restore all deleted files under /home, type:
j2restore /home
2. To restore inode 81 under /usr, type:
j2restore -i 81 /usr
3. To report what files are deleted under /dev/hd3, type:
j2restore -r /dev/hd3
Note:j2restore /home
2. To restore inode 81 under /usr, type:
j2restore -i 81 /usr
3. To report what files are deleted under /dev/hd3, type:
j2restore -r /dev/hd3
1. The fs must be unmounted before run j2restore.
2. After restore files using j2restore, the fs will be corrupted unless you use "-r" option, so we must run "fsck -y ".
Then we will find the restored files under lost+found directory.
3. j2restore could not restore deleted files if their disk block is re-used by other file. So you'd better un-mount fs as soon as possible when you find some files are mistakenly deleted.
4. Pls do not test this tool in your important system. I will take NO responsibility for any possible damage caused by j2restore.
5. Pls give me recommendation or comment if you have any problem when you use j2restore.
