... and the reason for this is because the current directory, called
"." (dot), is not normally in the PATH environment variable.  This
variable is used to find programs that you are trying to run.  Since
"." is not in that list, it will not find the script.

Adding the "./" in front of the command name tells the shell to "look
in this directory (.) for the command"
