How to Install rlwrap on Linux

Great utility to arrow UP/DOWN to choose the history commands as in DOS environment.

rlwrap is an utility that allows you to use up and down arrows like in DOS environment. For Oracle commands like sqlplus, rman, adrci, we can do the same as in DOS environment to choose one of the history command instead of type the same command again.

1) Downloand and install as a package from “http://rpm.pbone.net/” or an alternative web sites.

2) Yum install automatically.

alias impdp=”rlwrap impdp”
alias expdp=”rlwrap expdp”
# For GoldenGate
