[lug] Bash shell script question

[BC]

My Go code doesn't look remotely like yours, but I do remember seeing 
an os.Cmd structure that takes the environment into account. I 
experimented and found I didn't need to use that form.  But I'll go 
back and take another gander at it, just to be sure.  Go's slices are 
wonderful, aren't they?
