- Extract name and version field:
|
|
|
|
`recsel {{[-p|--print]}} name,version {{data.rec}}`
|
|
|
|
- Use "~" to match a string with a given `regex`:
|
|
|
|
`recsel {{[-e|--expression]}} "{{field_name}} ~ '{{regex}}' {{data.rec}}"`
|
|
|
|
- Use a predicate to match a name and a version:
|
|
|
|
`recsel {{[-e|--expression]}} "name ~ '{{regex}}' && version ~ '{{regex}}'" {{data.rec}}`
