+# Count The Number Of Matches In A Grep
+
+My go to way of counting the number of matches in a `grep` of a file is to pipe
+it to another command — `wc`.
+
+Here is what that looks like with the README for [this
+repo](https://github.com/jbranchaud/til). This counts the number of lines that
+start with `###`.
+
+```bash
+$ grep '^###' README.md | wc -l
+      48
+```
+
+When `wc` is used with the `-l` flag, it gives a count of the number of lines.
+In this case the number of `grep` matches that get piped to it.
+
+There is another way to do this solely with the `grep` command — using the `-c`
+flag.
+
+```bash
+$ grep -c '^###' README.md
+48
+```
+
+When you include the `-c` (or `--count`) flag with `grep`, instead of the
+matches being output, the count of the matches is output.
+
+See `man grep` for more details.
