SQL Injection Vulnerable Code Scanning Shell Command

heinous-shell-sqli-scanner.sh

# This heinous command searches for SQL injection vulnerable code:
# 1. Use awk to convert multiline strings into a single line
# 2. Fix things up with sed to make line endings normal again
# 3. Search for SQL-related statements
# 4. Search for lines where there are two or more $ variable indicators
#
# This is a hack. Please don't let this be my legacy.
