Linux Tutorial Series – 192 – while and until loops

Here is the video version, if you prefer it:

while and until loops are used for iteration, the same as for loops. However, I won’t teach you these. Why? Because, as (Ward, 2014)⁠ says, if you ever need a while loop (or an until loop), it’s a good time to move to another programming language. I agree.

I will tell you that (“Bash While Loop Examples,” n.d.)⁠ and a Google search will teach you, if you really must use them. But again, I will repeat myself: If you need to use a while or an until loop, switch to another programming language.

Thank you for reading!
