是否有办法显示一个命名空间的所有命令?例如，所有的命令都是教条吗?
这真的很好，因为我有很多命令和很多命令命名空间。
我知道
| grep <namespace>，但寻找一个内置的symfony选项，如果它存在假设我使用symfony2.0
只输入命名空间的开头，列出可用的命令:
$ php app/console doctrine
[InvalidArgumentException]
Command "doctrine" is not defined.
Did you mean one of these?
doctrine:query:sql
doctrine:query:dql
doctrine:schema:drop
doctrine:mapping:info
[…]
但是如果数字很低，它不会显示所有的命令:
$ php app/console doctrine:cache
[InvalidArgumentException]
Command "doctrine:cache" is ambiguous (doctrine:cache:clear-result, doctrine:cache:clear-query and 1 more).
也可以使用list命令，它将对命令进行排序并添加描述:
$ php app/console list doctrine
Symfony version 2.3.28 - app/dev/debug
Usage:
command [options] [arguments]
Options:
--help -h Display this help message
[…]
