* This is the meaning of the flags:

|

|
* w: write command (may modify the key space).

|
* r: read command (will never modify the key space).

|
* a: admin command, like SAVE or SHUTDOWN.
|

|
* p: Pub/Sub related command.
|
||||||
|
* f: force replication of this command, regarless of server.dirty. */
