• Command 1: find . -name '*.json' | xargs -I {} jq '{"file": input_filename, "MYCOLUMN": ..|.MYCOLUMN?}' {} | jq -c 'select(.MYCOLUMN | contains("詐騙"))' to find json files which content of column MYCOLUMN contains the string 詐騙.
• Command 2 for multiple keywords using boolean OR operator: find . -name '*.json' | xargs -I {} jq '{"file": input_filename, "MYCOLUMN": ..|.MYCOLUMN?}' {} | jq -c 'select(.MYCOLUMN | contains("詐騙") or contains("詐欺"))' to find json files which content of column MYCOLUMN contains the string 詐騙 or 詐欺.
