Compresses week-old log files in the current project four at a time. It has every shape that should worry you — a pipeline, sh -c, an argument placeholder — yet the inner command is only gzip, the path is relative, and the underscore correctly consumes $0 so filenames land in $1.
Think you can spot these under time pressure?
