Databases using this file format can be edited using any text editor. Recfiles allow for basic relational database operations, such as typing, auto-incrementing, as well as a simple join operation.
Recutils is a collection of tools, like recfmt, recsel, and rec2csv used to work with recfile databases. [4] Various software libraries support the format. [5] [6] [7]
Syntax
Data are stored in text files with empty lines separating records. Fields within a record are lines starting with their name and a colon; it is possible to wrap long entries. Multiple record types can be maintained in a single text file.
Example
# This is a recfile document.
%rec: Text
%type: Year int
Author: Doug McIlroy
Year: 1964
Note: The Origin of Unix Pipes
Title: Unix Text Processing
Author: Dale Dougherty
Author: Tim O'Reilly
Year: 1987
Publisher: Hayden Books
Author: William Shakespeare
Title: Hamlet
Year: 1599
Year: 1600
Year: 1601
This example command would output the following three lines (of the two original entries, one having two authors):
$ recsel -e 'Year > "1900"' -p Author
