+# Count The Number Of ripgrep Pattern Matches
+
+If I run [`ripgrep`](https://github.com/BurntSushi/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:
+
+```bash
+❯ 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.
+
+```bash
+❯ rg -c taco | awk -F: '{total += $2} END {print total}'
+40
+```
+
+[Using `:` as the field
+seperator](https://www.gnu.org/software/gawk/manual/html_node/Full-Line-Fields.html),
+`awk` is able to get the number on the left side (`$2`) for each and sum that
+up.
