Atomically sets multiple string keys with an optional shared expiration in a single operation.

## Required arguments

<details open><summary><code>numkeys</code></summary>

The number of keys being set.

</details>

<details open><summary><code>key value [key value ...]</code></summary>

A series of key/value pairs.

</details>

## Optional arguments

The following options modify the command's behavior. The condition options (`NX`, `XX`) are mutually exclusive, as are the expiration options (`EX`, `PX`, `EXAT`, `PXAT`, `KEEPTTL`).

<details open><summary><code>NX</code></summary>

Set the keys and their expiration time only if none of the specified keys exist.

</details>

<details open><summary><code>XX</code></summary>

Set the keys and their expiration time only if all of the specified keys already exist.

</details>

<details open><summary><code>EX seconds</code></summary>

Set the specified expiration time in seconds (a positive integer).

</details>

<details open><summary><code>PX milliseconds</code></summary>

Set the specified expiration time in milliseconds (a positive integer).

</details>

<details open><summary><code>EXAT unix-time-seconds</code></summary>

Set the specified Unix time in seconds (a positive integer) at which the keys will expire.

</details>

<details open><summary><code>PXAT unix-time-milliseconds</code></summary>

Set the specified Unix time in milliseconds (a positive integer) at which the keys will expire.

</details>

<details open><summary><code>KEEPTTL</code></summary>

Retain the time to live associated with the keys.
