Answer 1

Please note that Konstantin’s answer is better.

Just use echo with redis-cli like this:

# Delete list of cores
echo DEL cores | redis-cli

# Add a new core to the list of cores
echo LPUSH cores 1 | redis-cli 

# Wait forever for a core to become available
echo BLPOP cores 0 | redis-cli

Answer 2

It's is simpler to call commands directly, without pipelines:

> redis-cli -n 0 LPUSH mylist "hello"
(integer) 1

Be shure that you pass -n option, it's like mysql use <database> statement, it's set used database (first index is zero). When you run command from cli redis don't uses default database. To get information about databases which has some keys use command:

> INFO keyspace
db0:keys=4,expires=0,avg_ttl=0
