How can oracle flip through history commands like the Linux command line?

If you enter a piece of code or sql in oracle, you will find a syntax error after execution, or you may want to view the previously entered command.

Download rpm package rlwrap (32-bit and 64-bit rpm packages are provided in the attachment)

Http://rpmfind.net/linux/rpm2html/search.php?query=rlwrap

Install rlwrap-0.30-1.el5.i386.rpm

Rpm-ivh rlwrap-0.30-1.el5.i386.rpm

Modify the environment variables of the ORACLE user to generate rlwrap-related command aliases

Su-oracle

Vi .bash _ profile

# add at the end

Alias sql='rlwrap sqlplus'

Alias sqlplus='rlwrap sqlplus'

When alias lsnrctl='rlwrap lsnrctl'## is used to manage the monitoring service, you can turn over the history command with the up and down keys.

Alias rman='rlwrap rman'## for rman can flip the history command up and down

Reload .bash _ profile

Source .bash _ profile

If you have already started oracle or entered the instance, ask exit,shoutdown to restart oracle to enter the instance.
