Load a script into the scripts cache, without executing it.
After the specified command is loaded into the script cache it will be callable
using [`EVALSHA`](https://redis.io/docs/latest/commands/evalsha) with the correct SHA1 digest of the script, exactly like after
the first successful invocation of [`EVAL`](https://redis.io/docs/latest/commands/eval).

The script is guaranteed to stay in the script cache forever (unless `SCRIPT
FLUSH` is called).

The command works in the same way even if the script was already present in the
script cache.

For more information about [`EVAL`](https://redis.io/docs/latest/commands/eval) scripts please see [Introduction to Eval Scripts](https://redis.io/docs/latest/develop/programmability/eval-intro).
