rainbow greeting

greeting.sh

# my personal implementation of @florida's https://gist.github.com/florida/1839b047792b2d58f208a0913d4b2a6e 

# DEPENDENCIES:
  # - `lolcat` is the gradienterizer: https://github.com/busyloop/lolcat
 
# SETUP:  
# this file (greeting.sh) is in ~/bin 
# my .bash_profile includes this line to make all scripts in ~/bin globally accesscible:
  # - `export PATH=$PATH:~/bin`
# at the end of .bash_profile, it includes the line 
  # - `eval "sh greeting.sh"`
    # note: could probably just do `eval "sh <path/to/file>/greeting.sh"` so you don't have to use that first setup step of making it globally accessible?
  
# THE SCRIPT:
for i in $(seq 7); do
for i in $(seq $(tput cols)); do
    printf █
done
done | lolcat --freq=0.8 --spread $(tput cols)
