By default, the reply includes all of the server’s commands. You can use the optional command-name argument to specify the names of one or more commands.

The reply includes a map for each returned command. The following keys are always present in the reply:

• summary: short command description (always present).
• since: the Redis version that added the command (always present).
• group: the functional group to which the command belongs (always present). Possible values are:
  • bitmap

  • sorted-set
  • stream
  • string

The following keys may be included in the mapped reply as well:

• complexity: a short explanation about the command’s time complexity.
• doc-flags: an array of documentation flags. Possible values are:
  • deprecated: the command is deprecated.
  • syscmd: a system command that isn’t meant to be called by users.
• deprecated-since: the Redis version that deprecated the command.
• replaced-by: the alternative for a deprecated command.
• history: an array of historical notes describing changes to the command’s behavior or arguments. Each entry is an array itself, made up of two elements:

  2. The description of the change.
• arguments: an array of maps that describe the command’s arguments. Please refer to the Redis command arguments page for more information.
