Banner Countdown Timer
Hello. I am pretty new to unix and shell scripting and I was wondering if there might be a way to banner a countdown timer inside a script. We currently have an existing script that does a 2 minute sleep but thought it might be fun to actually make it banner a countdown timer until it is finished. Is this possible?

dancer::timer
Dancer::Timer(3pm) User Contributed Perl Documentation Dancer::Timer(3pm)
NAME
Dancer::Timer - a timer for Dancer
SYNOPSIS
use Dancer::Timer;
my $timer = Dancer::Timer->new();
my $time = $timer->tick;
print "[$time]: Doing something
";
# (time passes)
$time = $timer->tick;
print "[$time]: Doing something else
";
# (time passes)
$time = $timer->to_string;
print "[$time]: Doing another thing
";
DESCRIPTION
Dancer::Timer provides Dancer with a timing object to clock operations. For example, you might want a logging that shows you when each
operation happened (at what time) to determine how long each operation was in order to know where to focus on for possible bugs or perhaps
unnecessary slowness.
Dancer uses Dancer::Timer in facilities that want to provide this for you. Any plugin author is more than welcome to use it as well.
ATTRIBUTES
start_time
Retains the starting time of the timer. The default value is when the object is created. It fetches that using "gettimeofday" from
Time::HiRes.
METHODS
init
This method is called when "->new()" is called. It initializes the "start_time" attribute.
tick
Creates a tick in the timer and returns the interval between the "start_time" and now.
to_string
Same as "tick", just more expressive.
