Variable names in bash can have underscores in them, so
you need to do something like this to draw the line between
the variable name and your delimiters.

filename=${user}_${date}_${whatever}

This trick is useful if you are using a delimiter like "x".
Otherwise, how would bash know that the x's are not part
of the variable names?  filename=$userx$datex$whatever
will not work, filename=${user}x${date}x${whatever} will.
