Redis Delete key

Delete key in bulk

There is a command DEL that removes a single key in Redis, but it seems there is no instruction to delete the key in bulk, but we can do this with the Linux xargs command.

123	redis-cli keys "*"| xargs redis-cli del//如果redis-cli没有设置成系统变量，需要指定redis-cli的完整路径//如：/opt/redis/redis-cli keys "*" | xargs /opt/redis/redis-cli del

If you want to specify a Redis database access password, use the following command

1	redis-cli -a password keys "*"| xargs redis-cli -a password del

If you want to access a specific database in Redis, use the following command

12	//下面的命令指定数据序号为0，即默认数据库redis-cli -n 0 keys "*"| xargs redis-cli -n 0 del

Remove all keys

To delete all keys, you can use the FLUSHDB and Flushall commands of Redis

1234	//删除当前数据库中的所有Keyflushdb//删除所有数据库中的keyflushall

Note: The keys command can be fuzzy matched, but if the Key contains a space, it will not match, and temporarily did not find a good solution.
