How To Install libexpect-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libexpect-perl on Ubuntu 18.04.
What is libexpect-perl
libexpect-perl is:
The Expect module is a successor of Comm.pl and a descendent of Chat.pl. It more closely resembles the Tcl Expect language than its predecessors. It does not contain any of the networking code found in Comm.pl. I suspect this would be obsolete anyway given the advent of IO::Socket and external tools such as netcat.
Expect.pm is an attempt to have more of a switch() & case: feel to make decision processing more fluid. three separate types of debugging have been implemented to make code production easier.
It is now possible to interconnect multiple file handles (and processes) much like Tcl’s expect. An attempt was made to enable all the features of Tcl’s expect without forcing Tcl on the victim programmer :-) .
