Before you run a pipeline, use this command to check whether Redis has loaded the scripts you need. For missing scripts, use [`SCRIPT LOAD`](https://redis.io/docs/latest/commands/script-load); then use [`EVALSHA`](https://redis.io/docs/latest/commands/evalsha) instead of [`EVAL`](https://redis.io/docs/latest/commands/eval) in the pipeline to save bandwidth.\n\nFor more information about [`EVAL`](https://redis.io/docs/latest/commands/eval) scripts see [Introduction to Eval Scripts](https://redis.io/docs/latest/develop/programmability/eval-intro)."
