Linux/Unix desktop fun: Christmas tree on the terminal

Create a Christmas tree for your Linux or Unix console. Before that, install a Perl module named "Acme: POE: Tree. This is a very festive Christmas tree. I have verified it on Linux, OSX, and Unix-like systems.

 

Install Acme: POE: Tree

The simplest way to install the perl module is to use CPAN (Perl integrated collection Network (Comprehensive Perl Archive Network )). Open the terminal and press the following command to install Acme: POE: Tree.

1. ### Run as root ###
2. perl -MCPAN -e 'install Acme::POE::Tree'

Sample output:

1. Installing/home/vivek/perl5/man/man3/POE::NFA.3pm
2. Installing/home/vivek/perl5/man/man3/POE::Kernel.3pm
3. Installing/home/vivek/perl5/man/man3/POE::Loop.3pm
4. Installing/home/vivek/perl5/man/man3/POE::Resource.3pm
5. Installing/home/vivek/perl5/man/man3/POE::Filter::Map.3pm
6. Installing/home/vivek/perl5/man/man3/POE::Resource::SIDs.3pm
7. Installing/home/vivek/perl5/man/man3/POE::Loop::IO_Poll.3pm
8. Installing/home/vivek/perl5/man/man3/POE::Pipe::TwoWay.3pm
9. Appending installation info to /home/vivek/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/perllocal.pod

26. Result: PASS
27. RCAPUTO/Acme-POE-Tree-1.022.tar.gz
28. Tests succeeded but one dependency not OK (Curses)
29. RCAPUTO/Acme-POE-Tree-1.022.tar.gz
30. [dependencies] -- NA

 

Display the Christmas tree in Shell

Run the following command on the terminal:

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

Sample output

Tree Customization

The contents of tree. pl in my script file are as follows:

1. #!/usr/bin/perl
2. useAcme::POE::Tree;
3. my $tree =Acme::POE::Tree->new(
4. {
5. star_delay =>1.5,# shimmer star every 1.5 sec
6. light_delay =>2,# twinkle lights every 2 sec
7. run_for =>10,# automatically exit after 10 sec
8. }
9. );
10. $tree->run();

In this way, you can modify the starDelay, runThe value of the for and light_delay parameters comes from defining your tree. A fun terminal Christmas tree was born.
