-## read without -r mangles backslashes
-
-### Problematic code:
-
-    echo "Enter name:"
-    read name
-
-### Correct code:
-
-    echo "Enter name:"
-    read -r name
-
-### Rationale:
-
-By default, `read` will interpret backslashes before spaces and line feeds, and otherwise strip them. This is rarely expected or desired.
-
-Normally you just want to read data, which is what `read -r` does. All `read`s should use `-r` unless you have a good reason not to.
-
-Note that `read -r` will still strip leading and trailing spaces. `IFS="" read -r` prevents this.
-
-### Exceptions:
-
-If you want backslashes to affect field splitting and line terminators instead of being read, you can disable this message with a [[directive]].
