Thanks for this.

You are of course perfectly right. I tend not to think of this way of doing things - maybe because I originally learned Unix on HP-UX and SunOS a long time ago. I might be accused of being a little stuck in my ways!

I did think of mentioning this in the show but didn't do it because it was a "snippet" and I didn't want to go into too much detail and make the episode too long. I did link to the relevant page in the documentation (https://www.gnu.org/software/bash/manual/html_node/Quoting.html) however.

Feel free to add to the Bash Scripting series yourself. I look forward to hearing a different view from you in due course.
