Recursive implementation of List Dynamic Dependencies (LDD)
Recursive LDD (recursive-ldd) is a Perl script that allows displaying a tree-like hierarchy of shared library dependencies. The script calls on the standard Linux ldd utility in a recursion for every listed binary and library. It completes running when no matches are found in the current branch. It can also print unique values only as well as environment variables that affect the loading of libraries: LD_LIBRARY_PATH and LD_PRELOAD. Same limitations to standard ldd apply. Recursive-ldd cannot check libraries without read permissions.
