# shell command, assuming there are not tons of files in file_path:

grep -h ^CQA_STATUS file_path/cqa_* > file_path/CQA_STATUS


# but if there are tons of files, do it like this:

find file_path -name 'cqa_*' | xargs grep -h ^CQA_STATUS > file_path/CQA_STATUS

# (update: added carets where needed)
