您只需捕获输出并将其通过过滤器，如：
mysql show processlist
| grep -v '^\+\-\-'
| grep -v '^| Id'
| sort -n -k12
mysql show processlist
| grep -v '^\+\-\-'
| grep -v '^| Id'
| grep -v '^[0-9][0-9]* rows in set '
| grep -v '^ '
| sort -n -k12
较新版本的SQL支持信息模式中的进程列表：
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST
SELECT VERSION()
…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）： 上面将查询所有锁定的会话，并返回所涉及的信息和SQL …因此-假设您想查询正在睡眠的会话：
host=maindb
echo "show full processlist\G" | mysql -h$host | grep -B 6 -A 1 Sleep
host=maindb
user=me
password=mycoolpassword
echo "show full processlist\G" | mysql -h$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，以您想要的方式查询processlist。如果您使用旧版本的MySQL，您可以将\p与一些漂亮的awk代码结合使用。 这里有一个有趣的例子
这不正是您所需要的吗？命令行界面中的另一个有用工具是pager命令 乙二醇 然后你可以翻阅结果 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 寻呼机命令在每个会话中都是持久的。该命令
show full processlist
SELECT * FROM information_schema.processlist
WHERESELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';
mysqladmin processlist| sort -t\| -n -k7
人工分拣这很好，但它与
显示完整流程列表信息grepsedsed'/^\+\-\-/d；/^Id/d/^[0-9][0-9]*集合中的行'/d；/^/d这对一个程序（不是四个）进行一次调用，它更快、更干净、更简单，而且运行速度也更快。不需要，但可以。如果这是你想每秒做很多次的事情，那么，是的，担心性能。否则这不是问题，特别是考虑到数据集的大小。伙计，你可以在上面的代码示例中使用caroline****@****.com的电子邮件。
SELECT * FROM information_schema.processlist WHERE `INFO` LIKE 'SELECT %';
mysqladmin processlist| sort -t\| -n -k7
-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
