Description:
The mysql console includes help for "SHOW COLUMNS" but "help show" does not list "SHOW COLUMNS".

How to repeat:
Type "help show" and try to find "SHOW COLUMNS"

mysql> help show
Name: 'SHOW'
Description:
SHOW has many forms that provide information about databases, tables,
columns, or status information about the server. This section describes
those following:

SHOW CHARACTER SET [like_or_where]
SHOW COLLATION [like_or_where]
SHOW [FULL] COLUMNS FROM tbl_name [FROM db_name] [like_or_where]
SHOW CREATE DATABASE db_name
SHOW CREATE FUNCTION funcname
SHOW CREATE PROCEDURE procname
SHOW CREATE TABLE tbl_name
SHOW DATABASES [like_or_where]
SHOW ENGINE engine_name {LOGS | STATUS }
SHOW [STORAGE] ENGINES
SHOW ERRORS [LIMIT [offset,] row_count]
SHOW FUNCTION CODE sp_name
SHOW FUNCTION STATUS [like_or_where]
SHOW GRANTS FOR user
SHOW INDEX FROM tbl_name [FROM db_name]
SHOW INNODB STATUS
SHOW PROCEDURE CODE sp_name
SHOW PROCEDURE STATUS [like_or_where]
SHOW [BDB] LOGS
SHOW MUTEX STATUS
SHOW OPEN TABLES [FROM db_name] [like_or_where]
SHOW PRIVILEGES
SHOW [FULL] PROCESSLIST
SHOW PROFILE [types] [FOR QUERY n] [OFFSET n] [LIMIT n]
SHOW PROFILES
SHOW [GLOBAL | SESSION] STATUS [like_or_where]
SHOW TABLE STATUS [FROM db_name] [like_or_where]
SHOW TABLES [FROM db_name] [like_or_where]
SHOW TRIGGERS [FROM db_name] [like_or_where]
SHOW [GLOBAL | SESSION] VARIABLES [like_or_where]
SHOW WARNINGS [LIMIT [offset,] row_count]

like_or_where:
    LIKE 'pattern'
  | WHERE expr

The SHOW statement also has forms that provide information about
replication master and slave servers and are described in [HELP PURGE
MASTER LOGS]:

SHOW BINARY LOGS
SHOW BINLOG EVENTS
SHOW MASTER STATUS
SHOW SLAVE HOSTS
SHOW SLAVE STATUS

If the syntax for a given SHOW statement includes a LIKE 'pattern'
part, 'pattern' is a string that can contain the SQL "%" and "_"
wildcard characters. The pattern is useful for restricting statement
output to matching values.

Several SHOW statements also accept a WHERE clause that provides more
flexibility in specifying which rows to display. See

"SHOW COLUMNS" is listed but I did not see it,

SHOW [FULL] COLUMNS FROM tbl_name [FROM db_name] [like_or_where]
