Symbol link all DLLs in a folder:: for X in *.so.*; do ln -s $X ${X/.0.0/}; done
will create libexpr.so.3 -> libexpr.so.3.0.0 links

Unwind symbolic links::

$ file /usr/lib/libOSMesa.so*
/usr/lib/libOSMesa.so:     symbolic link to `libOSMesa.so.4.0'
/usr/lib/libOSMesa.so.4:   symbolic link to `libOSMesa.so.4.0'

List library dependencies:: ldd file         Linux 
 otool -L file    Mac

Symbol table:: nm -m -g file -m modules, -g externs
