Bash scripts study projects.

David

David is a programming legend.

In this simple bash script, I made a tribute to him while playing with colors using ASCII escape sequences.

Making it available as command everywhere

You can run this script with the following command, provided it's in the same directory where you execute it:

./david

But this doesn't do David justice. You want to make this command available everywhere.

• Add your /home/user/bin to the PATH variable (or whichever directory you prefer) and move the script to that directory:

mkdir ~home/<user_name>/bin
vim ~/.bashrc

• Add the following lines to .bashrc:

if [ -d ~/bin ]; then   
  PATH=$PATH:$HOME/bin  
  PATH=$PATH:/home/user/bin  
fi

• Run the following command:

source ~/.bashrc

You're good to go! Just run 'david' on the terminal and enjoy!
