Say I have an environment variable myvar:
myvar=\tapple\n
When the following command will print out this variable
perl -e 'print "$ENV{myvar}"'
I will literally have \tapple\n, however, I want those control chars to be evaluated and not escaped. How would I achieve it?
In the real world $ENV residing in substitution, but I hope the answer will cover that.
