+# Display Output In A Vertical Format
+
+Output for tables with lots of columns can be hard to read and sometimes
+overflow the terminal window. Consider the output from [Show Indexes For A
+Table](show-indexes-for-a-table.md):
+
+```sql
+> show indexes in users;
++-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
+| Table | Non_unique | Key_name     | Seq_in_index | Column_name | Collation | Cardinality | Sub_part | Packed | Null | Index_type | Comment | Index_comment |
++-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
+| users |          0 | PRIMARY      |            1 | id          | A         |           0 |     NULL | NULL   |      | BTREE      |         |               |
+| users |          0 | unique_email |            1 | email       | A         |           0 |     NULL | NULL   |      | BTREE      |         |               |
++-------+------------+--------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+
+```
+
+We can vertically orient the output of a statement by terminating it with
+`\G` instead of `;` (or `\g`).
+
+```sql
+> show indexes in users\G
+*************************** 1. row ***************************
+        Table: users
+   Non_unique: 0
+     Key_name: PRIMARY
+ Seq_in_index: 1
+  Column_name: id
+    Collation: A
+  Cardinality: 0
+     Sub_part: NULL
+       Packed: NULL
+         Null:
+   Index_type: BTREE
+      Comment:
+Index_comment:
+*************************** 2. row ***************************
+        Table: users
+   Non_unique: 0
+     Key_name: unique_email
+ Seq_in_index: 1
+  Column_name: email
+    Collation: A
+  Cardinality: 0
+     Sub_part: NULL
+       Packed: NULL
