Shell script check

Finds typical shell script defects without running the code: unquoted variables and command substitutions, legacy backticks, cd without an error check, cat in a pipeline, unquoted $@, an unknown or missing shebang, and variables that are assigned but never used. Each finding lists the rule code, level and line, plus a summary by level.
