Link to a specific inode

I have a file that was deleted, but is still held open my a program. I found the inode number using lsof. How can I create a hard link back to that inode?

Any code helps, but Perl would be handy.

Solution

  • Copy from /proc/pid/fd/file descriptor

    Use lsof to find the pid and the file descriptor.
