In my setup, the info command shows me the following:
[keys] => 1128 [expires] => 1125 I'd like to find those 3 keys without an expiration date. I've already checked the docs to no avail. Any ideas?

Normally Redis keys are created without an associated time to live. The key will simply live forever, unless it is removed by the user in an explicit way, for instance using the DEL command.
To list the keys in the Redis data store, use the KEYS command followed by a specific pattern. Redis will search the keys for all the keys matching the specified pattern. In our example, we can use an asterisk (*) to match all the keys in the data store to get all the keys.
Now technically you could just use the get command and if it returns an element then it means that the key exists and if it returns nil then it means that key did not exist.
Modified from a site that I can't find now.
redis-cli keys "*" | while read LINE ; do TTL=`redis-cli ttl "$LINE"`; if [ $TTL -eq -1 ]; then echo "$LINE"; fi; done; edit: Note, this is a blocking call.

@Waynn Lue's answer runs but uses the Redis KEYS command which Redis warns about:
Warning: consider KEYS as a command that should only be used in production environments with extreme care. It may ruin performance when it is executed against large databases.
Redis documentation recommends using SCAN.
redis-cli --scan | while read LINE ; do TTL=`redis-cli ttl "$LINE"`; if [ $TTL -eq -1 ]; then echo "$LINE"; fi; done; If you want to scan for a specific key pattern, use:
redis-cli --scan --pattern "something*" If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
