rlwrap – there’s a rpm for that

Recently, there has been discussion about using rlwrap for Goldengate on Twitter feed.

Truthfully, I did not know there was RPM for this and I did not even know it was already installed.

It just worked, when I had set it up.

A very nice cheat sheet for using yum.

I started to investigate how was rlwrap installed on the system.

OS Version.

$ cat /etc/issue
Oracle Linux Server release 6.6
Kernel \r on an \m

$ cat /etc/oracle-release
Oracle Linux Server release 6.6

Where’s rlwrap?

$ which rlwrap
/usr/bin/rlwrap

What’s rlwrap RPM?

rlwrap-0.42-1.el6.x86_64 : Wrapper for GNU readline
Repo        : installed
Matched from:
Other       : Provides-match: rlwrap

What’s rlwrap dependencies?

$ yum deplist rlwrap

Output omitted from brevity

Configure alias using rlwrap.

Using rpm commands.
