Redis batch deletes keys with specific prefixes

The methods usually given are as follows

./redis-cli -a password keys "test*" | xargs ./redis-cli -a password del

But this can be deleted in the case of a single machine , If it's in Redis Errors will be reported in the cluster ;

The experiment is as follows ：

Make numbers ：

for x in {1..100};do echo $x;redis-cli -h 127.0.0.1 -p 6379 set k$x v$x;done
 ~]# redis-cli -h 127.0.0.1 -p 6379 keys "k*"   
 1) "k52"
...
37) "k75"
38) "k3"
39) "k79"

  Delete

~]# redis-cli -h 127.0.0.1 -p 6379 keys "k*" | xargs redis-cli -h 127.0.0.1 -p 6379 del  
(error) CROSSSLOT Keys in request don't hash to the same slot

We can write a for Cycle to delete ;

for x in `redis-cli -h 127.0.0.1 -p 6379 keys "k*"`;do echo $x; redis-cli -h 127.0.0.1 -p 6379 del $x;done
