-a is like && 'and'
-e means existing at all
if -e is true it may be -d -f or fifo or socket, or such

I am using the following commands to validate a file or directory.

if [[ ! -f "$fl" && ! -d "$fl" ]]; then
printf '%s\n' "$fl: File or Directory does not exist"

But have noticed that I can use -e to see if there's something by that
name, instead of separately testing -f and -d.
Yet I am getting confused between using -a and -e.
