Let's say that I notice that the file referenced by the file name `quux' has more than one link:
$ ls -li quux 33059 -rw-r--r-- 2 reiter staff 172340 Jun 30 17:08 quux
To find the other links (names) of a file, you need to know the file's inode number, and in general also its filesystem (or rather the mount point of that filesystem).
You can see the inode number when you give the `-i' (or
`--inode') option to
ls. In the above example (`ls
-li'), it's the left-most field, 33059.
To find what filesystem a file belongs to, do `df file'. The mount-point of this filesystem is the last field, under the heading `Mounted on'. So in our example:
$ df quux Filesystem 1024-blocks Used Available Capacity Mounted on /dev/hda2 149806 123118 18952 87% /home
so the relevant mount point is `/home'.
Putting it all together, the general command is
mountpoint -xdev -inum inum (optionally --or necessarily,
if you don't use GNU find-- followed by `-ls', `-print' or
some such). To continue our above example:
$ find /home -xdev -inum 33059 -ls 33059 169 -rw-r--r-- 2 reiter staff 172340 Jun 30 17:08 /home/gonzo/grault 33059 169 -rw-r--r-- 2 reiter staff 172340 Jun 30 17:08 /home/reiter/corge/quux
