How to delete keys for which the value matches a pattern in Redis?

Reading Time: 1 minute


$ redis-cli --scan --pattern "car:vw*" | xargs redis-cli del


redis-cli – the Redis command line interface. It has an interactive REPL (Read Eval Print Loop) mode where the user types Redis commands and received replies, and a command mode where redis-cli is executed with additional arguments and the reply is printed to the standard output.

We use it in command mode to run the --scan command with the --pattern option that prints all the key names that match de specified pattern “car:vw*”.

Then, using xargs we use the output of the --scan command as input for the del command that removes the specified keys.
