Automated Testing

  • Test scripts created but not yet integrated into CI (will be done in separate PR)
  • Can be run manually: cd tests/pdsh_compat && ./run_all_tests.sh

Migration Impact

This PR provides complete resources for users migrating from pdsh:

  • Drop-in replacement capability via symlink
  • Comprehensive migration guide
  • Shell integration examples
  • Verification test suite

Related Issues

Closes #99

Notes

  • Some tasks deferred to separate PRs:
    • Homebrew formula update (symlink creation)
