The script can be loaded into the server's cache using the SCRIPT LOAD command. In all other aspects, this command behaves identically to EVAL, including how arguments are passed. ### Syntax The basic syntax of the redis Evalsha command is as follows: redis 127.0.0.1:6379> EVALSHA sha1 numkeys key [key ...] arg [arg ...] Parameter Description: * **sha1**: The sha1 digest generated by SCRIPT LOAD. * **numkeys**: Specifies the number of key name arguments. * **key [key ...]**: Starting from the third argument of EVAL, these represent the Redis keys used within the script. These key name parameters can be accessed in Lua via the global KEYS array, using 1-based indexing (KEYS, KEYS, and so on). * **arg [arg ...]**: Additional arguments, accessed in Lua via the global ARGV array, similar to the KEYS variable (ARGV, ARGV, etc.). ### Available Version >= 2.6.0 ### Example redis 127.0.0.1:6379> SCRIPT LOAD "return 'hello moto'""232fd51614574cf0867b83d384a5e898cfd24e5a" redis 127.0.0.1:6379> EVALSHA "232fd51614574cf0867b83d384a5e898cfd24e5a" 0"hello moto" !(#)(#) AI is thinking...
