(Again, depending I just want to print process info whitch have open a specific file£¨inode£©. Then if i want to delete a file in use,i can just kill the process one by one.
No kernel hacking needed for that, you can do it in userspace.
# lsof | grep /your/file/here # kill -9 ` lsof | grep /your/file/here | awk '{print $2} |uniq '`
Thank you very much for telling me those command. In fact, I want to write a rootkit check tool, I don't trust anything in user space. and I always want to known how to get the information by myself. Maybe i should check the source code of lsof, but it is really a difficult thing for me
