libtree

A tool that:

  • 🌳 turns ldd into a tree
  • ☝️ explains how shared libraries are found or why they cannot be located

Screenshot of libtree

Output

By default, certain standard dependencies are not shown. For more verbose output use

  • libtree -v Show libraries skipped by default
  • libtree -vv Show dependencies of libraries skipped by default
  • libtree -vvv Show dependencies of already encountered libraries

Use the --path or -p flags to show paths rather than sonames:

  • libtree -p $(which tar)

Use --max-depth to limit the recursion depth.

Install

  • Prebuilt binaries for v3.1.1
