UNIX for Dummies Questions & Answers

No particular reason, except that it is quicker to write "21" than "${#var_arr[@]}" and less chance of a typo...
Also arrays give you the ability to hop about in any order with relative ease.
If the list can do that then it is an unknown to me...

Hope this makes sense...

True, but you don't need to hop about in any order here, so why change from a list ($var) to arrays if all you do is enumerate?
If you are using "21" then if the number of items in $var changes you need to als change that number too, which you would not need to do with ${#var_arr[@]}

Because as is so often the case an example shown is a starter and there is very often a qualifier further into the thread.

However with my methods I put it down to two things:-

1) As an amateur without formal training I have a different thought approach to solving problems.
2) I code to work, not work to code.

Apart from stuff I never get involved with and consequently no nothing about, much of the stuff I have put on here is the result of stretching the shell as far as possible to achieve a result.

What reaslly surprises me though is if I can do a solution, (good or bad), how is it some _professionals_ are incapable of doing so?

As the saying goes "there is more than one way to skin a cat"...

I will say at this point though, I do thank you big guns for steering me to _better_ways_ of doing things...

Apologies for deviating from the thread and veering OT...
