GETEX

Syntax

GETEX key [EX seconds | PX milliseconds | EXAT unix-time-seconds | PXAT unix-time-milliseconds | PERSIST]

Time complexity: O(1)

Get the value of key and optionally set its expiration. GETEX is similar to GET, but is a write command with additional options.

Options

The GETEX command supports a set of options that modify its behavior:

• EX seconds -- Set the specified expire time, in seconds.
• PX milliseconds -- Set the specified expire time, in milliseconds.
• EXAT timestamp-seconds -- Set the specified Unix time at which the key will expire, in seconds.
• PXAT timestamp-milliseconds -- Set the specified Unix time at which the key will expire, in milliseconds.
• PERSIST -- Remove the time to live associated with the key.

When supplied with no options, GETEX is equivalent to GET.

Return

Bulk string reply: the value of key, or nil when key does not exist.
