I want to take input from an external file(containing list of variables) and assign it to the variables in my manifest file by grepping the equivalent values.

**variables.txt** name='abc' port=404 user="xyz" **createuser.pp** $readfile = file('variables.txt'), $name = (i want the value in vaiable.txt to be read here) $readfile is getting all the contents of variables.txt into it, but i want only the subsequent values of the variables assigned to them in .pp file as it is in variables.txt. Please help if it is possible. Thanks, Anu
