Redis import scripts

Insert hundreds of thousands of data into the key names to provide the name when the player logs on to the game for the first time. The solution is to save all namescontent in suijiming.txt text.
Script

#! /Bin/bash

While read line

Do

Echo $ line

Redis-cli lpush names $ line

Done <suijiming.txt

Blocked word

Import the shielded words to redis, and create a key,dirty_names. then, import the shielded words to the database in the pingbizi.txt text.

#! /Bin/bash

While read line

Do

Echo $ line

Redis-cli sadd dirty_names $ line

Done <pingbizi.txt
