Linux / Unix Desktop Fun: Christmas Tree For Your Terminal

Linux / Unix Desktop Fun: Christmas Tree For Your Terminal

Let us create Linux or Unix console Christmas tree just for fun and profit. First, you need to install a Perl module called Acme::POE::Tree. It is an animated Christmas tree module. I’ve tested this on Linux, OS X and Unix-like system.

Install Acme::POE::Tree

The easiest way to install any perl module is to use the cpan (Comprehensive Perl Archive Network). Open the terminal application and type the following command to install Acme::POE::Tree:

## run as root ##
perl -MCPAN -e 'install Acme::POE::Tree'

## run as root ##
perl -MCPAN -e ‘install Acme::POE::Tree’

Sample outputs:

Show Christmas tree in the shell

Simply type the following command:

perl -MAcme::POE::Tree -e 'Acme::POE::Tree->new()->run()'

perl -MAcme::POE::Tree -e ‘Acme::POE::Tree->new()->run()’

Sample outputs:

Tree customization

Here is my tree.pl:

#!/usr/bin/perl
 
use Acme::POE::Tree;
my $tree = Acme::POE::Tree->new(
{
  star_delay => 1.5,  # shimmer star every 1.5 sec
  light_delay => 2,   # twinkle lights every 2 sec
  run_for => 10,      # automatically exit after 10 sec
}
);
$tree->run();

#!/usr/bin/perl
use Acme::POE::Tree;
my $tree = Acme::POE::Tree->new(
{
star_delay => 1.5, # shimmer star every 1.5 sec
light_delay => 2, # twinkle lights every 2 sec
run_for => 10, # automatically exit after 10 sec
}
);
$tree->run();

Now can play with your tree modifying star_delay, run_for, and light_delay. And ,there you have it a a Christmas tree in your shell for fun. If you enjoyed this desktop fun app, you may also like to use the following apps on Linux:
