+# Apply Multiple Substitutions To The Input
+
+You can apply multiple substitutions to the input of a `sed` command a couple
+ways.
+
+One of those ways is to use the `-e` flag multiple times to define
+substitutions that should be _appended_ to the `sed` script.
+
+```bash
+$ echo 123 | sed -e 's/3/three/' -e 's/1/one/'
+one2three
+```
+
+Another way is to define a single string as the `sed` script and separate each
+substitution with a `;` (semicolon).
+
+```bash
+$ echo 123 | sed 's/3/three/; s/1/one/'
+one2three
+```
+
+Each of these will run each substitution in the `sed` script sequentially for
+each line in the input.
