---
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`]({{< relref "/commands/evalsha" >}}) with the correct SHA1 digest of the script, exactly like after
the first successful invocation of [`EVAL`]({{< relref "/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`]({{< relref "/commands/eval" >}}) scripts please refer to [Introduction to Eval Scripts]({{< relref "/develop/programmability/eval-intro" >}}).
