+## In Dash, echo flags besides -n are not supported.
+
+### Problematic code:
+
+```sh
+#!/bin/dash
+echo -e "Name:\t$USER"
+```
+
+### Correct code:
+
+```sh
+#!/bin/dash
+printf 'Name:\t%s\n' "$USER"
+```
+
+### Rationale:
+
+Your script uses a shell feature not supported by the shebang. Either rewrite the script to be portable, or change the shebang to explicitly require a shell like Bash.
+
+In this case, you can rewrite your use of `echo` using `printf`, which behaves the same across shells.
+
+### Exceptions:
+
+None
