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 Author: Doug McIlroy Author: Dale Dougherty Author: Tim O'Reilly
