bash_ct Changelog

V4.3.0

Added

Conflict Analysis Mode (-c)

  • Introduced ct -c for environment-wide command name collision analysis

  • Scans:

    • aliases
    • functions
    • builtins
    • keywords
    • external $PATH commands (presence-only detection)

  • Reports resolution hierarchy (what wins in Bash precedence order)

  • Detects shadowing relationships across all categories

External command integration in conflict mode

  • External binaries are reported as:

    • external(shadowed)

  • No full $PATH resolution is performed in -c mode (intentional simplification)

  • Reduces:

    • output noise
    • false positives from PATH ordering ambiguity
    • runtime overhead in large environments

Changed

Output semantics

  • Conflict mode reports name collisions only
  • Trace mode remains responsible for full resolution + filesystem inspection

Improved

Code cleanup

  • fixed nameref usage for cleaner internal references

  • Reduced reliance on global variables

  • _ct_resolve optimized for reuse in both trace and conflict modes

    • now caches compgen results
    • reduces repeated shell calls
    • improved performance for -c mode in large environments
