Currently the "opts" variable is not zero-ed and we keep on adding to it, ending up with: $ check-headers.sh 2>&1 + opts=' "-B"' + opts=' "-B" "-B"' + opts=' "-B" "-B" "-B"' + opts=' "-B" "-B" "-B" "-B"' + opts=' "-B" "-B" "-B" "-B" "-B"' + opts=' "-B" "-B" "-B" "-B" "-B" "-B"' Fix this by initializing it in the check() function, right before starting the loop.
