Hi,
We briefly discussed this on IRC, but: it would be nice if requestctl had a feature of the form "show me actions using pattern foo".
One can achieve this with a jq-based thing:
requestctl get action -o json | jq 'to_entries | .[] | select(.value.expression|test("ua/FISH")) | "action: \(.key), expression: \(.value.expression)" '
# outputs:
"action: cache-text/FISH, expression: pattern@ua/FISH"[I swapped in FISH to avoid leaking anything]
...but a proper CLI argument to achieve similar would be great.
