Code Review
This pull request refactors bin/idstack-learnings-search by extracting duplicated fallback search logic into a reusable shell function fallback_search(). The review feedback recommends improving the robustness and POSIX compliance of this function by using "--" to prevent option injection in grep and replacing the obsolete "tail -$LIMIT" syntax with "tail -n $LIMIT".

Robustness & Standards Compliance
- Option Injection: If
$KEYWORDor$TYPEstarts with a hyphen (e.g.,-v),grepwill interpret it as a command-line option rather than a search pattern. Using--signals the end of options and prevents this. - POSIX Compliance: The
tail -"$LIMIT"syntax is obsolete/deprecated in modern POSIX standards. Usingtail -n "$LIMIT"is the standard, portable way to specify the line limit.
if [ -n "$KEYWORD" ]; then
cat $SOURCES 2>/dev/null | grep -i -- "$KEYWORD" | tail -n "$LIMIT"
elif [ -n "$TYPE" ]; then
cat $SOURCES 2>/dev/null | grep -- "\"type\":\"$TYPE\"" | tail -n "$LIMIT"
else
cat $SOURCES 2>/dev/null | tail -n "$LIMIT"
fi

🎯 What: Extracted the duplicate fallback search logic into a reusable shell function named
fallback_search.💡 Why: Improved maintainability and readability by replacing two identical
if/elif/elseblocks with a single function, eliminating 14 lines of duplicate code.✅ Verification:
./test/smoke-test.shand./test/integration-test.sh), which all passed successfully.✨ Result: Clean, readable search logic that preserves all original functionality without modifying behavior.
