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

This should work:

function grep_search() {
    declare magic_variable_$1="$(ls | tail -1)"
    echo "$(tmpvar=magic_variable_$1 && echo ${!tmpvar})"
}
grep_search var  # calling grep_search with argument "var"
