 ====== BASH - Files - Read a file - Read from an interactive shell ======
+<code bash>
+read foo

+<WRAP info>
+**NOTE:**  This will store the input into a variable named **$foo**.

+====== Handling backslash interpretation ======
+<WRAP info>
+**NOTE:**  The **-r** option is often used with read:
+  * **-r**:  Prevents backslash interpretation (usually used as a backslash newline pair, to continue over multiple lines or to escape the delimiters).
+    * Without this option, any unescaped backslashes in the input will be discarded.
+    * You should almost always use the **-r** option with read.
+The most common exception to this rule is when **-e** is used, which uses Readline to obtain the line from an interactive shell.
+  * In that case, tab completion will add backslashes to escape spaces and such, and you do not want them to be literally included in the variable.
+  * This would never be used when reading anything line-by-line, though, and **-r** should always be used when doing so.
