Stupid bash scripting question

[Cole Tuininga]

Ok - I'm sure the answer to this is simple, but I can't seem to figure
the darned thing out.  In my defense, it's extremely rare that I do any
shell scripting.  8)

Basically, the deal is that I have a variable that contains a string
such as "~username".  I'd like to actually expand that to the user's
home directory.

In other words, if I have something like:

user="username"
f="~${user}"

I'd like $f to end up with the path to username's actual home.  As it
is, it just has the value "~username".  What magic do I need to do on my
f assignment line?!
