Returns information about the existence of the scripts in the script cache.
This command accepts one or more SHA1 digests and returns a list of ones or
zeros to signal if the scripts are already defined or not inside the script
This can be useful before a pipelining operation to ensure that scripts are
loaded (and if not, to load them using
SCRIPT LOAD) so that the pipelining
operation can be performed solely using EVALSHA instead of EVAL to save
Please refer to the EVAL documentation for detailed information about Redis Lua scripting.
Array reply The command returns an array of integers that correspond to the specified SHA1 digest arguments. For every corresponding SHA1 digest of a script that actually exists in the script cache, an 1 is returned, otherwise 0 is returned.
