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

/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"
