have to determine all users home directories - tilde scripting problem

Question

Assume someuser has a home directory /home/someuser

NAME=someuser

In bash - what expression to I use combining tilde (~) and $NAME to return the users home d

Answer 1

Tilde ( ~ ) it's the same as $HOME so, not all the user will have as root to home the same directory.

But if you insist in using the tilde this do the work:

echo ~/../$NAME

See:

$ pwd
/home/oreyes
$ export NAME=john 
$ export DIRECTORYNAME=~/../$NAME
$ cd $DIRECTORYNAME
$ pwd
/home/john
