The syntax is as follows:

Stores, lists, executes, edits of the commands

Entered during the current SQL*Plus session.

HIST [ORY] [N {RUN | EDIT | DEL [ETE]}] | [CLEAR]

N is the entry number listed in the history list.

Use this number to recall, edit or delete the command.

Example:

HIST 3 RUN-will run the 3rd entry from the list.

HIST [ORY] without any option will list all entries in the list.

The process is as follows:

[oracle@cjcos ~] $sqlplus / as sysdba

SQL > hist

SP2-1650: History is off, use "SET HIST [ORY] ON" to enable History.

SQL > set hist on

SQL > show pdbs
