Dynamic variable names in Bash

Question

I am confused about a bash script.

I have the following code:

function grep_search() {
    magic_way_to_define_magic_variable_$1=`ls | tail -1`
    e         


        

Answer 1

An extra method that doesn't rely on which shell/bash version you have is by using envsubst. For example:

newvar=$(echo '$magic_variable_'"${dynamic_part}" | envsubst)
