How to Use

# Move the the folder where the fonts are available. This script supports only otf and ttf.
# Then simply run the script like
$ ./path/to/script/install-fonts.sh 

Or you can add an alias to the ~/.bashrc or ~/.zshrc

alias install-fonts='/path/to/script/install-fonts.sh'

This script currently works on Mac OSX only.

Prerequisite

Run the following command to create ~/.ssh folder if it doesn't already exist and set the right access permission.

{ { { mkdir ~/.ssh && echo "No ~/.ssh found so just created" } || { echo "~/.ssh already exists"; false }  } ; chmod 700 ~/.ssh }

Once done, please check if you have the folder with the right access permission.

fib 0 = 0
fib 1 = 1
fib 2 = 1
fib n = fib (n - 1) + fib (n - 2)
-- Get the 100th number 
fib 100
-- But it takes too long.
-- You can do it with zipWith like the following line and it works much faster
fibs = 0 : 1 : 1 : zipWith (+) (drop 1 fibs) (drop 2 fibs)
