Count The Number Of ripgrep Pattern Matches

If I run ripgrep with a pattern against a project with many files, I may get a bunch of matches. So many matches even that they scroll off the screen.

To get a summary of the number of matches in each file, I can include the -c flag:

❯ rg -c taco
rails/parse-query-params-from-a-url.md:6
rails/params-is-a-hash-with-indifferent-access.md:4
ruby/fetch-warns-about-superseding-block-argument.md:1
ruby/add-comments-to-regex-with-free-spacing.md:1
ruby/create-a-csv-table-object.md:2
ruby/a-basic-case-statement.md:4
ruby/triple-equals-the-case-equality-operator.md:1
ruby/build-http-and-https-urls.md:4
rspec/check-specific-arguments-to-received-method.md:2
javascript/check-classes-on-a-dom-element.md:1
javascript/spread-merging-objects-includes-nil-values.md:2
xstate/custom-jest-matcher-for-xstate-machine-states.md:1
postgres/checking-inequality.md:1
case.rb:4
python/test-a-function-with-pytest.md:6

That is still a bunch of info and I may want to further summarize by getting a count of the total number of matches. I can do this by piping these results to an awk command that totals them up.

❯ rg -c taco | awk -F: '{total += $2} END {print total}'
40

Using : as the field seperator, awk is able to get the number on the left side ($2) for each and sum that up.
