GNU Recutils is a set of tools and libraries to access human-editable, plain text databases called recfiles. The data is stored as a sequence of records, each record containing an arbitrary number of named fields

I'm amused that, while I use the *format* and edit it in my $EDITOR, I almost never use the actual recutils recsel(1) for querying because it's quicker to just use the search functionality in my editor to find the records of interest, compared to remembering the recsel query syntax.
About all I use is recfix(1) to sanity-check…it occasionally catches duplicate IDs, broken foreign-key references (such as my address-book having familial links like "father: johnsmith"), or malformed field-values.
