bash script source: No such file or directory

I have a script that begin like this

#!/bin/bash
VALKYRIE=~/myProjects/valkyrie
source $VALKYRIE/cluster.conf

but when I run it it returns line 2: ~/myProjects/valkyrie/cluster.conf: No such file or directory

but the file exist and when I run source ~/myProjects/valkyrie/cluster.conf it runs fine. Any idea? I set VALKYRIE variable elsewhere so hard-code in the path isn't an option.

~ doesn't appear to be expanding properly. When I run your script with an intentionally fake path, the error doesn't say ~, but expands the path (i.e. /home/sparhawk/fakepath not ~/fakepath. You could try using $HOME instead of ~, or using the full path in the script instead.

(I'm not sure why ~ doesn't work on your system, as your script works fine for me.)
