较新版本的 SQL 支持 information_schema 中的进程列表：

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST

您可以以任何您喜欢的方式订购。

在 MySQL 5.1.7 中添加了 INFORMATION_SCHEMA.PROCESSLIST 表。您可以找出您正在使用的版本：

SELECT VERSION()

命令 

show full processlist

可以替换为：

SELECT * FROM information_schema.processlist

但如果你使用后一个版本，你可以在WHERE其中添加子句：

SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';

来自命令行界面的另一个有用的工具是 pager 命令。

例如

pager grep -v Sleep | more; show full processlist;

然后，您可以对结果进行分页。

您还可以通过这种方式使用 grep 或 sed 查找某些用户、IP 或查询。

pager 命令在每个会话中都是持久的。

您可以捕获输出并将其通过过滤器，例如：

mysql show processlist
    | grep -v '^\+\-\-'
    | grep -v '^| Id'
    | sort -n -k12

这两个 grep 去掉了标题和尾行（如果有其他行不包含有用信息，则可能需要其他行），并且根据数字字段编号 12 进行排序（我认为这是正确的）。

这适用于您的即时输出：

mysql show processlist
    | grep -v '^\+\-\-'

如果你使用旧版本的 MySQL，你总是可以使用 \P 结合一些不错的 awk 代码。有趣的例子在这里

这不正是您需要的吗？

...我们还没有更新版本的 MySQL，所以我能够做到这一点（仅适用于 UNIX）：

 host=maindb

 echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Locked

以上将查询所有被锁定的会话，并返回涉及的信息和SQL。

...所以-假设您想查询正在休眠的会话：

  host=maindb

  echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep

或者，假设您需要为 MySQL 提供额外的连接参数：

  host=maindb

  user=me

  password=mycoolpassword 

  echo "show full processlist\G" | mysql -h$host -u$user -p$password | grep -B 6 -A 1 Locked

通过一些调整，我确信可以轻松创建一个 shell 脚本来按照您想要的方式查询进程列表。

使用“|” 作为分隔符

mysqladmin processlist| sort -t\| -n -k7

来自 排序手册 ( man sort)

   -k, --key=KEYDEF
          sort via a key; KEYDEF gives location and type

  -t, --field-separator=SEP
            use SEP instead of non-blank to blank transition

   -n, --numeric-sort
          compare according to string numerical value

   -r, --reverse
          reverse the result of comparisons
