  • thank you, but I want the name of my new var to contain the content of VAR_ONE. I don't want to create _var of any other static name Commented Nov 17, 2023 at 19:50
  • So, I successfully created a var called "newvar${VAR_ONE}". This is my intention. This variable exists, I can verify with env | grep newvar. My challenge is: how do I address this new variable e.g. in an "echo" statement? – Commented Nov 17, 2023 at 19:55
  • the new variable name does contain the content of VAR_ONE, see the last echo which verifies the new variable (named as desired) exists ; in a separate comment you asked how you can go about referencing the newly created variable ... this shows how you can reference that new variable via the nameref, see echo "${_var}" Commented Nov 17, 2023 at 19:57

    I'm sorry to take so much of your time. I'm a +60y old engineer who never had any coding class in his life. I am trying to understand, but my 2 brain-cells are boiling now. I understand that last echo... but in my case, I don't know the contents of VAR_ONE (being "thisIsVarOne"). In your last echo, you are using that contents. Commented Nov 17, 2023 at 20:04

    re: nameref ... imagine you have 3 brothers (Larry, Moe, Curly), the label brother would be similar to a nameref; if you establish that brother=Moe then you can proceed to reference Moe by the label 'brother' ... brother can you spare a dime, how old are you brother; now suppose you establish that brother=Larry then you can proceed to reference Larry by the label 'brother' ... brother can you spare a dime, how old are you brother; clear as mud? :-) Commented Nov 17, 2023 at 20:16
