ffe 命令

常用示例

说明

ffe (Flat File Extractor) parses fixed-width and delimited flat files according to a structure definition provided in a configuration file. It extracts fields and can convert data to formats such as CSV or XML. Configuration files define record layouts with field names, widths, and types.
