+# `read`
+
+`read` is primarily used to capture `stdin` from the user and automatically parse it as variables. It has a secondary use case as a command that the `stdout` is piped to. This enables you to capture the output of a command as one or more variables which you can then execute subsequent operations on.
+
+## `stdin`
+
+```bash
+$ read var1 var2
+$ thomas bishop # user inputs this
+$ echo $var2
+$ bishop
+```
+
+> If you don't specify variables, `read` will automatically parse using whitespace
+
+## `stdout`
+
+```bash
+find -type -f  -not -path "./.git/" | read $fname
+```
