A quick way to delete redis keys from the command line would be:
redis-cli DEL "del_key"
If you wish to delete all keys matching a certain pattern,
redis-cli KEYS "*del_pattern*" | xargs redis-cli DEL
A more easy shell script for it would be:
Save it as redis-delete.sh and you can just run it as:
./redis-delete.sh del_pattern
UPDATE:
The above code using KEYS does not scale well and so for a more performance efficient code, we can use SCAN which is a cursor-based iterator.
Just note that `KEYS` can potentially run for a long time and consume a significant amount of RAM while Redis prepares the reply. An alternative and safer approach is using `SCAN` - see here for a sample script that uses it: http://stackoverflow.com/a/23399125/3160475
ReplyDeleteThanks for the info. Learnt a new thing. I have added an update above using SCAN.
DeleteNicely done :)
DeleteI need to add space and ; to rhe code when I used it
ReplyDeletewhile [ $cursor -ne 0 ]; do
if [ $cursor -eq -1 ]; then
cursor=0
