recsel

Print records from a recfile: a human-editable, plain text database. More information: https://www.gnu.org/software/recutils/manual/recutils.html.

• Extract name and version field:

recsel -p name,version {{data.rec}}

• Use "~" to match a string with a given regular expression:

recsel -e "{{field_name}} ~ '{{pattern_regex}}' {{data.rec}}"

• Use a predicate to match a name and a version:

recsel -e "name ~ '{{pattern_regex}}' && version ~ '{{pattern_regex}}'" {{data.rec}}
