Just finished a 12 hour bash class and started writing this program to get some practice. I would like to continue but not sure that Bash is capable of much more. I may take a "C" class soon but my instructor suggested Python as the next step.

Any suggestions are appreciated.

#!/bin/bash
# NOTE this worked as a simple display of one hand and dealing the deck

# Sets array1 to the numbers 0 to 51
deck_numbers=( $( seq 0 51 ) )

# Bash's command substitution syntax to store the results of the tput command
term_clear=$(tput clear)

# Stores the number of lines or rows on the terminal display
max_lines=$(tput lines)

# Stores the number of columns on the terminal display
max_cols=$(tput cols)

# Clear the screen
echo $term_clear

I tried uploading the script but that didn't happen for some reason. Sorry that the indenting was lost on the copy paste.
