Certainly NOT the best solution, but it works (emergencies) My redis database contains only 1213 entries, so the processing time is acceptable.
I use a bash script (commented out the line that actually deletes the entry, dry run before you uncomment that line). #!/bin/bash mapfile -t keysArray < <(redis-cli --scan) for (( i=0; i<${#keysArray[@]}; i++ )); do data=$(echo "dump ${keysArray[i]}" | redis-cli | tr -d '\0') if [[ "${data}" == *"accounts"*"google"*"com"* ]]; then echo "${keysArray[i]}" # redis-cli del "${keysArray[i]}" fi done In order to look at the redis database, I use a web interface ( https://packagist.org/packages/erik-dubbelboer/php-redis-admin) My install script for this (into /var/www/html), using lighttpd #!/bin/bash sudo apt-get -y install libtool sudo apt-get -y install php7.4-dev sudo apt-get -y install php-redis sudo apt-get -y install php-mbstring cd /var/www/html sudo git clone https://github.com/ErikDubbelboer/phpRedisAdmin.git cd phpRedisAdmin sudo git clone https://github.com/nrk/predis.git vendor
