Finding Files
2.2.2 Hard Links
To find hard links, first get the inode number of the file whose links
you want to find. You can learn a file's inode number and the number of
links to it by running `ls -i' or `find -ls'. If the file has
more than one link, you can search for the other links by passing that
inode number to `-inum'. Add the `-xdev' option if you are
starting the search at a directory that has other filesystems mounted on
it, such as `/usr' on many systems. Doing this saves needless
searching, since hard links to a file must be on the same filesystem.
See section 2.10 Filesystems.
- Test: -inum n
- File has inode number n.
You can also search for files that have a certain number of links, with
`-links'. Directories normally have at least two hard links; their
`.' entry is the second one. If they have subdirectories, each of
those also has a hard link called `..' to its parent directory.
- Test: -links n
- File has n hard links.
