April 28, 2020From 2:32 to 2:49 I showed an example of using double-quotes and single-quotes. You need to know more though. Within double quotes variables will be interpreted; however, with single quotes they won't. So the text within single quotes will be echoed literally. Play with it on your end so this nuance sinks in and let me know here if you have questions. -Paul

April 28, 2020In the first example at 2:15, Linux took "echo – – help" literally and echoed what came after the echo command. Why is this happening? Well it won't happen on all systems, and the short answer is that it has to do with built-ins that don't pull the appropriate help, so the workaround is to call the program and option using "/path/echo – – help". I hope that helps. -Paul
