In redis, there is no command to delete keys directly according to regular expressions, only the Del key1 command

However, redis has a command to obtain keys through regular expressions: keys “regular expressions”

You can delete keys in batches with the help of xargs command, and pass the found key value to del as a parameter

redis-cli keys “xxxx*” | xargs del

Full command

redis-cli -h 192.169.1.71 -p 7001 -a 123456 keys xxxx* | xargs -r -t -n1 redis-cli -h 192.169.1.71 -p 7001 -a 123456 del

[note]

The xargs command needs to be followed by the parameter – R, otherwise when the number of keys is 0, an error will be reported err wrong number of arguments for ‘del’ command

The parameter – N1 should be added after the xargs command. Otherwise, when the number of cluster keys is greater than 1, an error may be reported: crosslot keys in request don’t hash to the same slot

It is OK not to add – T. adding – t will output the content deleted each time. If not, the deleted content will not be output, but the number of keys deleted each time will still be output
