Suppose I have a variable in my bash script:
conf="~/Downloads"
where Downloads is an existing directory under my home directory.
The following complains that directory does not exist:
realpath $conf
How do I expand a path stored in a variable?
Please note that, in the actual script of mine, conf contains input from user, who may or may not input tilde. Hence, writing conf=~"/Downloads" is not an option.
UPDATE: Unfortunately, the question has been marked as duplicate and I cannot reply. The solution is to transform the value by eval "conf=$conf".
