I know from the document that tilde expansion only works if the string
is unquoted (see below)

~$ cd '~/..'
-bash: cd: ~/..: No such file or directory
~$ cd ~/..
/Users$

I'm wondering if I already have a string variable, is there a bash
native to do tilde expansion on it.

var='~/..'
cd $var#how to change this line?

  eval "cd $var"
