# EVALSHA
**EVALSHA sha1 numkeys key [key ...] arg [arg ...]**
根据给定的 sha1 校验码,对缓存在服务器中的脚本进行求值。
将脚本缓存到服务器的操作可以通过 [_SCRIPT LOAD_](script_load.html#script-load) 命令进行。
这个命令的其他地方,比如参数的传入方式,都和 [_EVAL_](eval.html#eval) 命令一样。
**可用版本:**
>= 2.6.0
**时间复杂度:**
根据脚本的复杂度而定。
```
redis> SCRIPT LOAD "return 'hello moto'"
"232fd51614574cf0867b83d384a5e898cfd24e5a"
redis> EVALSHA "232fd51614574cf0867b83d384a5e898cfd24e5a" 0
"hello moto"
```
