############################
###
### Purpose: To provide an insanely over-engineered solution for saving the 0.735 seconds
###          it takes to manually open for editing the markdown file that hugo generates on:
###          hugo new path/to/markdown.md
###
### Dependencies: $EDITOR, sh, expr, read, sed, wc, printf, column, date, hugo
###
### Written and Tested on: Ubuntu 20.10
###
### Note: While this is written in /bin/sh in an attempt to be portable, YYMV 
###       due to the fact that this is my first pure /bin/sh script. Feedback/advice
###       is always welcome.
###
