The exit code used to provide a simple reply to the calling script or process as to the result of executiing the script. Code zero means it worked. Other codes are chosen by the script writer.
A calling script will find that the value of the exit code is in the Environment Variable $?
So would it be better practice to end my script with exit 0 instead of just exit?

The awk looks for any white space between fields and outputs the first field ($1).
So the $1 in the first part of that line of code ls -log "$1" is referring to the parameter of the script (in this case, a directory name), but the $1 in the second part of that line of code awk '{print $1}' is referring to the first field (in this case, the permissions), right?

Sorry, I don't understand this command.
By using f_count=$(grep -c "-........." $TF), I was trying to say count the number of lines that start with a - (which would signify a file, as opposed to a d, for directory, of course) and are followed by any variation of rwx permissions (this is why I tried using the "dot" wildcard . nine times). Should I have instead written f_count=$(grep -c "-.*" $TF)? My thinking is still probably wrong...

f_count=$(grep -c \^\- $TF)
Could you please explain what the \^\- does?

SYNOPSIS
#include <allegro.h>
FONT *extract_font_range(FONT *f, int begin, int end)
DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this
function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the
font. Example:
FONT *myfont;
FONT *capitals;
FONT *fontcopy;
...
/* Create a font of only capital letters */
capitals = extract_font_range(myfont, 'A', 'Z');
/* Create a copy of the font */
fontcopy = extract_font_range(myfont, -1, -1);
