我正面临创建数据库的问题,并导致以下错误.

这是我的用户表.

我将空闲超时设置为 60 分钟。但是，在使用与 Python 服务器通信的 Python 客户端进行测试时，发送 POST 时，连接会在约 5 分钟不活动时由对等方重置。即使连接重置或断开后，该活动仍在服务器端发生。

我正在尝试使用 redis 服务器中的模式删除密钥，但它没有被删除。

示例按键

命令

redis-cli 密钥 *sandeep-pant* | xargs redis-cli DEL

输出

xargs: WARNING: a NUL character occurred in the input.  It cannot be passed through in the argument list.  Did you mean to use the --null option?
xargs: unmatched double quote; by default quotes are special to xargs unless you use the -0 option
(integer) 0

我试图计算文件中单词的出现次数.

如果一行中出现多次单词,我将计算为1.

以下命令将为我提供输出,但如果行有多次出现单词,则会失败

grep -c "word" filename.txt

有没有一个班轮？
