12 Giu 14 How to declare a read only variable in bash
I didn’t know that it was possible to declare a read only variable in bash.
It’s as simple as to run the following statement:
declare -r a=10
This will create a read only variable called $a with value 10 that you cannot overwrite or unset.
Cool!!
