Untangle Links

How to find the terminal pathname of a file/directory? For example, the file /usr/lib64/mozilla/plugins/libjavaplugin.so will be installed by IcedTea-web java plugin. It is a symbolic link to another link. The command namei enables us to untangle links by following each pathname until the endpoint is found.

Here is an example usage and its output:

%namei /usr/lib64/mozilla/plugins/libjavaplugin.so
f: /usr/lib64/mozilla/plugins/libjavaplugin.so
 d /
 d usr
 d lib64
 d mozilla
 d plugins
 l libjavaplugin.so -> /etc/alternatives/libjavaplugin.so.x86_64
   d /
   d etc
   d alternatives
   l libjavaplugin.so.x86_64 -> /usr/lib64/IcedTeaPlugin.so
     d /
     d usr
     d lib64
     - IcedTeaPlugin.so

which untangles /usr/lib64/mozilla/plugins/libjavaplugin.so by following links and gets its terminal pathname:
/usr/lib64/IcedTeaPlugin.so.
