ffe

Extract fields from a flat database file and write to another format. A configuration file is required to interpret the input and format the output. More information: https://ff-extractor.sourceforge.net/ffe.html.

  • Display all input data using the specified data configuration:

ffe {{[-c|--configuration]}} {{path/to/config.ffe}} {{path/to/input}}

  • Convert an input file to an output file in a new format:

ffe --output={{path/to/output}} {{[-c|--configuration]}} {{path/to/config.ffe}} {{path/to/input}}

  • Select input structure and print format from definitions in ~/.fferc configuration file:

ffe {{[-s|--structure]}} {{structure}} {{[-p|--print]}} {{format}} {{path/to/input}}

  • Write only the selected fields:

ffe {{[-f|--field-list]}} "{{FirstName,LastName,Age}}" {{[-c|--configuration]}} {{path/to/config.ffe}} {{path/to/input}}

  • Write only the records that match an expression:

ffe {{[-e|--expression]}} "{{LastName=Smith}}" {{[-c|--configuration]}} {{path/to/config.ffe}} {{path/to/input}}
